Could it be that these are dependencies of wacom which is a dependency
of libinput? In that case you can try replacing libinput with libinput-minimal.

I soc that doesn't support an sd card won't support linux either ;-)

Generally flash is used for the bootloader and then linux or guixsd is
loaded from an sd card...

Thanks for the hint, I got the following during libinput -> libinput-minimal
transition, not sure it is a real problem, though:

/tmp/guix-build-libinput-minimal-1.4.0.drv-0/libinput-1.4.0/libtool: line 1734:
ldconfig: command not found

Size of bare-bones guixsd

[Vincent Legoll]

Hello,

I'm wondering if there's interest in reducing the bare-bones system
footprint, there are some X / GUI stuff in there that may / could /
should be trimmed IMHO...

And what would be the way to do this ?

Like what?

I would take a look at gnu/system.scm which, if I understand correctly,
implements the core of GuixSD.

Variables like %base-packages and %base-firmware might be interesting to
look at.

By the way, people usually ask about *adding* things to the bare-bones
example :)

I know these probably come from indirect dependencies of other tools,
for advanced features... (please remember that I come with a long
background of gentoo negated use flags)

libXpm, cairo, libxcb, randrproto, glibmm, randrproto, mkfontscale,
inputproto, imagemagick, xtrans, gtk+, compositeproto, cups*, inkscape,
xextproto, freetype, libXrender, gdk-pixbuf, libxcb, libXdmcp, libXaw,
xcb-proto, pixman, netpbm, libvorbis, libcddb, openjpeg, atkmm, libxmu,
libx11, etc...

And I may have missed some...

Some come probably as "guix graph" deps...

I was thinking of bare-bone just as what that name implies, just what is
needed for booting, guix dependencies, and nothing more...

As if I was designing an embedded system with no place in the flash
for anything superfluous, maybe that was a bad assumption...

I'll first try to remove some from the %base-packages list and see what is
trimmable...

Maybe make a real bare-bones, and then based upon this one, a more "usable"
CLI-system, with more stuff added.

Hi!

Sorry for the late reply.  This would be interesting, and the starting
point would be to look at the output of:

  guix size $(guix system build gnu/system/examples/bare-bones.tmpl)

I think the X stuff is pulled by lsh.
