[Bug 1978426] Re: "ignore" mount option set for autofs is not observed

[Maarten Jacobs]

Sorry for the delayed reply - couldn't get back to this sooner.

Other than "mount" and "gio mount" that I already mentioned, I also see
the same effect in Chrome (the dialog that opens when I do a "save as"
on a webpage. I also see the same thing in Eclipse, although by
appearance it uses the same dialog as Chrome does.

I'm still looking for other examples - I don't have any file managers
other than Thunar installed.

I can report that the same effect is also present on my Raspberry Pi -
running Raspberry Pi Os (aka debian) - so I don't think the problem is
unique to Ubuntu.

Title:
  "ignore" mount option set for autofs is not observed

Status in autofs package in Ubuntu:
  New
Status in thunar package in Ubuntu:
  New

Bug description:
  I am thinking autofs is not the right package for this, but the
  behavior is related to it.

  I have various NFS mounts configured with autofs, and invariably all
  of these mounts are reported twice by 'mount' as well as 'gio mount
  -l'. Similarly my file manager (Thunar) also shows these mounts twice.

  When I run 'mount', I see the same mount twice:

  /etc/auto.<redacted> on /home/<redacted>/Documents type autofs (rw,relatime,fd=7,pgrp=11462,timeout=300,minproto=5,maxproto=5,direct,ignore,pipe_ino=167388)
  <redacted>:/storage/Documents on /home/<redacted>/Documents type nfs4 (rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=<redacted>,local_lock=none,addr=<redacted>)

  I've anonymized the entries a bit. The first entry is created when the
  master map is read, the second one is the "actual" NFS mount (created
  when I access the mount point).

  I've enabled "use_ignore_mount_option" in my autofs.conf - not quite
  sure if that's what caused the "ignore" option to be included on the
  autofs entry. But "ignore" is on the autofs line, and by the
  description of that option, it should cause user space applications to
  ignore the mount. Which apparently isn't happening.

  Hence my earlier statement that I don't think autofs is the problem -
  I think it's doing what it's supposed to - but the other applications
  are not observing the mount option.
