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