[bug#75810] [PATCH v7 00/16] Rootless guix-daemon

[Ludovic Courtès]

Hello,

Changes compared to v6 (all suggested by Reepca):

  • Canonicalize the builder’s file name before ‘execve’
    and add the “builder is outside the store” test in
    ‘tests/derivations.scm’ (though the test would already
    succeed before due to the ELF interpreter being unavailable
    in the chroot).

  • Explicitly close both ends of the ‘readiness’ pipe.

  • Use ‘mkdir -p’ to create /var/log/guix in ‘guix-install.sh’.

Thoughts?

Ludo’.

Ludovic Courtès (16):
  daemon: Use ‘close_range’ where available.
  daemon: Close the read end of the logging pipe.
  daemon: Bind-mount /etc/nsswitch.conf & co. only if it exists.
  daemon: Bind-mount all the inputs, not just directories.
  daemon: Remount inputs as read-only.
  daemon: Remount root directory as read-only.
  daemon: Allow running as non-root with unprivileged user namespaces.
  daemon: Create /var/guix/profiles/per-user unconditionally.
  daemon: Drop Linux ambient capabilities before executing builder.
  daemon: Move comments where they belong.
  linux-container: ‘unprivileged-user-namespace-supported?’ returns #f
    on non-Linux.
  tests: Add missing derivation inputs.
  tests: Run in a chroot and unprivileged user namespaces.
  etc: systemd services: Run ‘guix-daemon’ as an unprivileged user.
  guix-install.sh: Support the unprivileged daemon where possible.
  DRAFT gnu: guix: Update to f447941.
