Comment 38 for bug 1771858

When we disabled the generator in snapd we added a regression test (tests/main/snap-system-env):
https://github.com/snapcore/snapd/pull/6470/files

With the current systemd (not the one in -proposed) I get:
```
grep error: pattern not found, got:
LANG=C.UTF-8
PATH=/sbin:/usr/sbin:/bin:/usr/bin:/snap/bin
```
which is expected and shows that the generator is broken.

When running the same regression test with the systemd in -proposed I get no error so the update looks fine (as far as our test case goes). I heard some concerns from xnox about systems with initrd that need to be explored too.
