This patch series introduces two new services;

 - seatd-service-type: simple seat management daemon
 - greetd-service-type: simple login daemon

Both services are very minimalistic in nature. Simple seatd daemon could
be said as replacement for elogind-service-type. greetd daemon is simple
replacement for mingetty/agetty.

In addition to the base services, special build of pam-mount module is
included as seatd-pam-mount. It is used to provide auto-(mounting/unmounting)
of XDG_RUNTIME_DIR. Special build is required to avoid interference with
default pam-mount if used in the system.

greetd provides agreety terminal greeter out of the box. Current
greetd-service-type includes configuration for greetd-agreety-session
variations, i.e. only terminal are supported at the moment.

Next step would be adding gtkgreet and/or wlgreet alternatives for
graphical greeter.

This package inherits pam-mount in the way that it is compiled
specifically for use with seatd daemon. It uses different
configuration location and name space for storing data in PAM.

seatd-pam-mount is used in configuration of seatd to provide
auto-(mounting/unmounting) of XDG_RUNTIME_DIR in the way that
it will not interfere with default pam-mount configuration.

A seat management daemon, that does everything it needs to do.
Nothing more, nothing less. Depends only on libc.

This patch series introduces two new services;

 - seatd-service-type: simple seat management daemon
 - greetd-service-type: simple login daemon

Both services are very minimalistic in nature. Simple seatd daemon
could be said as replacement for elogind-service-type. greetd daemon
is simple replacement for mingetty/agetty.

In addition to the base services, special build of pam-mount module is
included as greetd-pam-mount. It is used to provide
auto-(mounting/unmounting) of XDG_RUNTIME_DIR. Special build is
required to avoid interference with default pam-mount, if used in
the system.

greetd provides agreety terminal greeter out of the box. Current
greetd-service-type includes configuration for greetd-agreety-session
variations, i.e. only terminal are supported at the moment.

Next step would be adding gtkgreet and/or wlgreet alternatives for
graphical greeter.

This package inherits pam-mount in the way that it is compiled
specifically for use with greetd daemon. It uses different
configuration location and name space for storing data in PAM.

greetd-pam-mount is used in configuration of greetd to provide
auto-(mounting/unmounting) of XDG_RUNTIME_DIR in the way that
it will not interfere with default pam-mount configuration.

A seat management daemon, that does everything it needs to do.
Nothing more, nothing less. Depends only on libc.

greetd is a minimal and flexible login manager daemon that makes
no assumptions about what you want to launch.

Currently, only agreety configuration is provided.

The synopsis should not end with a period.  “This” doesn’t really bring
anything, maybe something like

  Rust library that quotes, unquotes, and unescapes strings

See “16.4.4 Synopses and Descriptions” in the manual for more details.

The synopsis should not end with a period.

The description should contain one or more complete sentences, see
“16.4.4 Synopses and Descriptions” in the manual.

No need to ‘mkdir-p’ if you will call ‘install-file’ on the directory.

Why not put these four lines inside the (with-directory-excursion "man"
…) form, and remove the "man" prefix?

Phases don’t need to return #t once the ‘core-updates’ branch gets
merged.

The synosis is a bit long, maybe

  Minimal and flexible login manager daemon

“what you want to launch” sounds a bit vague, is it referring to desktop
environment, window manager, or something else?

It might be a good idea to put this in a comment in the code too.  :-)

The description should also be updated.

‘documentation’ field is missing.

Missing ‘description’ field.

It might also be a good idea to write a system test for the service, you
can look at the (gnu tests …) modules for examples.

I am not familiar with how seatd works, so I can’t really comment too
much.  :-)

/gnu/store/....-missiles-1.01/bin/launch why not? :D

in next update, i will try to put some more sentences from greetd
description, it might be more useful may be.

This patch series introduces two new services;

 - seatd-service-type: simple seat management daemon
 - greetd-service-type: simple login daemon

Both services are very minimalistic in nature. Simple seatd daemon
could be said as replacement for elogind-service-type. greetd daemon
is simple replacement for mingetty.

In addition to the base services, special build of pam-mount module is
included as greetd-pam-mount. It is used to provide
auto-(mounting/unmounting) of XDG_RUNTIME_DIR. Special build is
required to avoid interference with default pam-mount, if used in
the system.

greetd provides agreety terminal greeter out of the box. Current
greetd-service-type includes configuration for greetd-agreety-session
variations, i.e. only terminal are supported at the moment.

Next step would be adding gtkgreet and/or wlgreet alternatives for
graphical greeter.

This patch series introduces two new services;

 - seatd-service-type: simple seat management daemon
 - greetd-service-type: simple login daemon

Both services are very minimalistic in nature. Simple seatd daemon
could be said as replacement for elogind-service-type. greetd daemon
is simple replacement for mingetty.

In addition to the base services, special build of pam-mount module is
included as greetd-pam-mount. It is used to provide
auto-(mounting/unmounting) of XDG_RUNTIME_DIR. Special build is
required to avoid interference with default pam-mount, if used in
the system.

greetd provides agreety terminal greeter out of the box. Current
greetd-service-type includes configuration for greetd-agreety-session
variations, i.e. only terminal are supported at the moment.

Next step would be adding gtkgreet and/or wlgreet alternatives for
graphical greeter.

+greetd is a minimal and flexible login manager daemon that makes no
+assumptions about what you want to launch.
+
+If you can run it from your shell in a TTY, greetd can start it. If it
+can be taught to speak a simple JSON-based IPC protocol, then it can
+be a greeter.
+
+@code{<greetd-service-type>} provides necessary infrastructure for
+logging in users, including:
+
+@itemize @bullet
+@item
+@code{greetd} PAM service
+
+@item
+Special variation of @code{pam-mount} to mount @code{XDG_RUNTIME_DIR}

+
+@item @code{allow-empty-passwords?} (default: @code{#t})
+Allow empty passwords by default so that first-time users can log in when
+the 'root' account has just been created.

+
+@item @code{terminal-vt} (default: @samp{"7"})
+The VT to run on. Use of a specific VT with appropriate conflict avoidance

This patch series introduces two new services;

 - seatd-service-type: simple seat management daemon
 - greetd-service-type: simple login daemon

Both services are very minimalistic in nature. Simple seatd daemon
could be said as replacement for elogind-service-type. greetd daemon
is simple replacement for mingetty.

In addition to the base services, special build of pam-mount module is
included as greetd-pam-mount. It is used to provide
auto-(mounting/unmounting) of XDG_RUNTIME_DIR. Special build is
required to avoid interference with default pam-mount, if used in
the system.

greetd provides agreety terminal greeter out of the box. Current
greetd-service-type includes configuration for greetd-agreety-session
variations, i.e. only terminal are supported at the moment.

Next step would be adding gtkgreet and/or wlgreet alternatives for
graphical greeter.

Also adds greetd-next which is built from master that includes
configurable terminal switch flag, required for smooth operation.

+This package inherits pam-mount in the way that it is compiled specifically

+This package inherits pam-mount in the way that it is compiled specifically
+for use with greetd daemon. It uses different configuration location and
+name space for storing data in PAM.

+greetd-pam-mount is used in configuration of greetd to provide
+auto-(mounting/unmounting) of XDG_RUNTIME_DIR in the way that it will not

Currently, only agreety greeter and its configuration is provided.

* gnu/services/base.scm (greetd-service-type): New variable
* gnu/services/base.scm (pam-limits-service-type): Should be
aware of greetd PAM service
* gnu/services/pam-mount.scm (pam-mount-pam-service): Should be
aware of greetd PAM service.

Thanks for working on these patches!

I just applied them to the current master branch and tried building all
the new packages, but libseat fails to build like this:

------

Sorry if I forgot about how to apply the patch series... does it need to
go on another branch besides master?

Hi,

Ah yes, on master you will need to set:

    (arguments
     `(#:meson ,meson-next

I was testing the patches on both core-updates-frozen and master. 
For me both
braches was applicable without change. Except on master, meson 
should be next.
Sorry for forgetting that.

Thanks in advance,
muradm

Hello,
I would be looking to use this, seems unfortunate the merge has halted at a very advanced point -- any chance it gets picked up again? :)
Would be trying to package the QtGreet application that i use on my other system/partition, if it was.
Thanks,
Florian

Hi,

overall this works quite well for me, thanks!

A few comments:

> +                  #:log-file
> +                  (string-append "/tmp/greetd." #$greetd-vt ".log")))
Why log to /tmp and not /var/log here?

> +                   #:log-file "/tmp/seatd.log"))
Same.

> * gnu/packages/admin.scm (libseat): New variable
> * gnu/packages/admin.scm (seatd): New variable
> * gnu/packages/freedesktop.scm (seatd): Remove variable
(gnu packages wm) references seatd, but does not use (gnu packages admin),
thus `guix pull` fails.

Only a single independent change per patch.

Most likely not a native input but a non-native input that needs to be
cross-compiled when rust-pam-sys is cross-compiled.

Description is missing, this just repeats the synopsis.

Greetings,
Maxime.

Fixing as suggested:
* splitting rust packages to commit per package
* linux-pam should be in 'inputs
* varying description

Thanks in advance,
muradm

Hi, is there anything else needed to be updated for merging?

Thanks in advance,

Hi,

any chance of getting that system test working? It currently backtraces for me:
