[Bug 1659719] Re: ssh can't call a binary from a snap without the full path

[Steve Langasek]

I know that work was done to ensure /snap/bin was in the default path
for systemd itself and that this should be inherited now by all units.
'systemd-path | grep search-binaries:' shows that it's there on my focal
system.  'sudo ps axewwww | grep sshd' also shows that it's set in the
PATH environment of the sshd parent processes.  So I'm not sure what is
still resetting the PATH for noninteractive ssh sessions.

Bug description:
  ssh can't call a binary from a snap, it will only work using the full
  path.

  Let's say I have the hello snap installed in 192.168.122.24. Then:

  elopio at ubuntu-xenial:~/mosh$ ssh 192.168.122.24 hello
  elopio at 192.168.122.24's password:
  bash: hello: command not found
  elopio at ubuntu-xenial:~/mosh$ ssh 192.168.122.24 /snap/bin/hello
  elopio at 192.168.122.24's password:
  Hello, world!
