[bug#31360] [PATCH 0/5] 'guix pack --relocatable'

Hello Guix!

This is the cleaned up version of what we discussed at:

Part of the work here is to use relative symlinks in profiles and in
links created with ‘guix pack -S’ such that, if you run:

  guix pack -R -S /mybin=bin bash-static

you can then unpack the result and run:


For ‘guix pack -R’ I started providing the framework so that ‘guix pack
--bootstrap’ would use the bootstrap C compiler, which in turn would
allow us to add a unit test.  Unfortunately, since ‘glibc-bootstrap’
lacks ‘libc.a’, we cannot do that.

Anyway feedback welcome!  I invite you to give it a try if you have a
non-Guix machine at hand, it’s pretty fun.  :-)

What remains to be seen is the implications for the binary installation
tarball: what if we created it with -R?  Would it be of any use?  I
guess ‘guix-daemon’ would still need to run with --disable-chroot
because build users would be missing.  Maybe we should change
‘guix-daemon’ to do something sensible in that case?


Ludovic Courtès (5):
  union: Add 'relative-file-name'.
  profiles: Optionally use relative file names for symlink targets.
  profiles: Allow lowerable objects other than packages in
  search-paths: Add 'set-search-paths'.
  pack: Add '--relocatable'.                               |   3 +-
