Comment 23 for bug 1771858

Just noticed what might be a regression from this fix. `/usr/local/sbin:/usr/local/bin` are now missing from unit on newest ubuntu bionic ami (us-east-1: ami-012fd5eb46f56731f)

ubuntu@ubuntu:~$ dpkg-query -W systemd
systemd 237-3ubuntu10.11
ubuntu@ubuntu:~$ sudo systemd-run /usr/bin/env
Running as unit: run-r6c6668bf9774455dbb628d2d79de5949.service
ubuntu@ubuntu:~$ journalctl -e | grep PATH=
Feb 01 20:46:24 ubuntu env[6051]: PATH=/sbin:/usr/sbin:/bin:/usr/bin:/snap/bin

The prior ami (us-east-1: ami-0b86cfbff176b7d3a) doesn't have this issue. So I checked for differences. I noticed that if I remove `/usr/lib/systemd/system-environment-generators/snapd-env-generator` and reboot then I get better output:

ubuntu@ubuntu:~$ sudo systemd-run /usr/bin/env
Running as unit: run-r6c6668bf9774455dbb628d2d79de5949.service
ubuntu@ubuntu:~$ journalctl -e | grep PATH=
