[bug#58812] [PATCH 0/5] Add --symlink option to 'guix shell'.

[Maxim Cournoyer <maxim.cournoyer@gmail.com>]

Hi,

I've wanted this enough times now to finally get around implementing it :-).
My main use case for it will be creating a /usr/bin/env symlink in 'guix
shell' environments for portability with the #!/usr/bin/env
shebang.

While at it, I've improved error reporting and made it fail early when a
symlink would point to a nonexistent file (dangling symlink).

The test suite passes, and I've run the basic system test as well as the
'btrfs-root-os' one successfully.

Thanks,

Maxim Cournoyer (5):
  Makefile.am: Sort EXTRA_DIST entries.
  tests: Add a tests/utils.sh support file.
  install: Validate symlink target in evaluate-populate-directive.
  guix: shell: Add '--symlink' option.
  shell: Detect --symlink spec problems early.
