[Group.of.nepali.translators] [Bug 1771858] Re: /snap/bin not in default PATH for units, snapd should ship system-environment-generators to inject /snap/bin into $PATH

[Launchpad Bug Tracker]

This bug was fixed in the package systemd - 237-3ubuntu10.24

---------------
systemd (237-3ubuntu10.24) bionic; urgency=medium

  [Dimitri John Ledkov 🌈]
  * core: export environment when running generators.
    Ensure that manager's environment (including e.g. PATH) is exported when
    running generators. Otherwise, one is at a mercy of running without PATH 
which
    can lead to buggy generator behaviour. (LP: #1771858)

Bug description:
  [Impact]

   * This means that software installed via snap isn't transparently
  available for units to use.  As snaps are first-class citizens in
  Ubuntu, we should update the PATH.

   * When a generator started to be provided by systemd, it was
  recognized that $PATH is not correctly set, nonetheless, due to an
  environment bug that systemd generators run in.

  [Testcase]

  # make snapd-env-generator executable if it is not
  $ sudo chmod +x 
/usr/lib/systemd/system-environment-generators/snapd-env-generator

  # reboot, then test the effect of the fix
  $ systemd-run /usr/bin/env
  $ journalctl -e | grep PATH

  Output should contain /snap/bin

  Output should contain a complete and a valid PATH, i.e.
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin" 
or similar.

  [Regression Potential]

   * snapd generator was already fixed separately to cause no harm, when
  running under a broken systemd. With the corrected environment,
  generators will now run with a correct PATH out of the box. A slight
  change of PATH will be observed by all generators, when running in
  containers/initramfs-less boots. However most generators will not be
  affected as they typically do not execute external binaries.
