Comment 11 for bug 1784774

With the additional information in https://bugs.launchpad.net/snapd/+bug/1821193 I think we can fix this issue quickly.

1) The mountinfo parser will now look for an automount point that mentions autofs, an example line is mentioned here:

137 29 0:50 / /home rw,relatime shared:87 - autofs /etc/auto.master.d/home rw,fd=7,pgrp=22588,timeout=300,minproto=5,maxproto=5,indirect,pipe_ino=173399

2) We could optionally look at the referenced file (/etc/auto.master.d/home) and parse it, in this case it contains this line (among others)

* -fstype=nfs,vers=4,rw,soft,rsize=8192,wsize=8192 prodpeda-samba.domain.fr:/home/&

With this information we can enable the workaround reliably.

I will not do 2) at first, unless reviewers deem it necessary.
