guix fail to reconfigure the system

[Maitja Obid]

Hi,

I have freshly installed guixsd distribution. Afer running guix pull and
system build i was trying to switch into newly built system with
system reconfigure which gives me next error:

  root@hostname ~# guix system reconfigure /etc/config.scm
  guix system: error: stat: No such file or directory: "system"

What can be wrong?

No idea at first sight.  Could you share your config.scm?

Thanks,

The meaning of 'device' depends of 'title', whose default value is
'device.  So right now Guix looks for a node under /dev, but there is no
/dev/system.

You probably forgot to add (type 'label), if "system" refers to the file
system label name.  Or alternatively you could use (device "/dev/sdaX").

You can have a look at
https://www.gnu.org/software/guix/manual/guix.html#index-file_002dsystem
for more details.

Good luck!
Clément

In general I think `guix system` error feedback tends to be a tad too
shy.  Are there some plans to make them more explicit and precise?

Did you know that you can ask for more verbose feedback with the
--on-error option?  See (guix) Invoking guix system for details.

No I had missed that!  Thanks for pointing it out!

Never tell a lie unless it is absolutely convenient.

According to the manual this is the default strategy:

|nothing-special|

    Report the error concisely and exit. This is the default strategy.

Which in the case of Matija reports:

    guix system: error: stat: No such file or directory: "system"

Maybe we should add to this error message an information about the 
ability to choose another error strategy (to have more information about 
what went wrong), e.g.:

    guix system: error: stat: No such file or directory: "system"
    Note: More information on the error is availiable by choosing another error strategy.
    See (guix) Invoking guix system for details.

Cheers

For the record, this error was really a bug.  Ironically, the bug was
introduced as we added more sanity checks to ‘guix system’ that would
prevent users from doing ‘init’ or ‘reconfigure’ for a system that would
fail to boot.   :-)

Anyway, this commit fixes it:

Thanks,

I like it.  Any plan to implement this idea?
