Package: libpam-mount
Version: 2.14-1
Severity: important
Using "tmpfs" to avoid an SSD being written to continuously, and to
discard files at reboot. I started off with a line like:
<volume group="users" fstype="tmpfs" mountpoint="/home/%(USER)/mycache/"
options="size=1G,uid=%(USER),mode=0700" />
If I logged in multiple times, however, i would get multiple tmpfs
mounted on top of each other, which is certainly wrong and not what I want
(eg, a loging would make all previous files in cache disappear!!).
By enabling verbose logging, turns out that:
1) pam-mount, at login, decides if a file systems needs to be mounted
again based on the output of mount, and content of /proc/mounts.
2) if a mount is already visible in /proc/mounts, it does not mount it.
If it is missing, it adds it.
3) with verbose logging, it seems like that without the "path" attribute
in the <volume> definition, path is interpreted as "(null)" and it looks
for '/' in the output of /proc/mounts? However, the linux kernel has
"none" in the same line (probably as a result of how it was mounted).
The two don't match, so the file system is mounted again and again.
4) if I add a "path" attribute to the <volume> definition, like with:
<volume group="users" fstype="tmpfs" path="mycache"
mountpoint="/home/%(USER)/mycache/" options="size=1G,uid=%(USER),mode=0700" />
And then login and run mount, I now see:
[...]
mycache on /home/ccontavalli/mycache type tmpfs
(rw,relatime,size=1048576k,mode=700)
[...]
instead of:
[...]
none on /home/ccontavalli/mycache type tmpfs
(rw,relatime,size=1048576k,mode=700)
[...]
... and logging out now works.
What I'd like to see is either:
1) determine this is "expected behavior", and document it.
2) fix the code so an unspecified "path" is treated correctly (eg, doesn't
try to match for / or whatever it is trying to match on), and just does
the right thing.
2) is more desirable to me than 1).
