Hello, I'm trying to set up a LUKS-encrypted user's home partition which would be automounted when the user logs in.
I've installed libpam-mount and added the following line into /etc/security/pam_mount.conf.xml: <volume user="andrey" fstype="crypt" path="/dev/disk/by-partuuid/..." mountpoint="~" /> Automounting works fine, but I'm having trouble with auto-unmounting when I log out. The partition stays mounted and I can see "target is busy" errors from umount in the journal. If I edit logout entry inside pam_mount.conf.xml to look like this: <logout wait="10000000" hup="no" term="yes" kill="yes" /> I can see during the first 10sec period that my home dir is held by pulseaudio and dbus-daemon. Then pam_mount terminates them successfully with SIGTERM, waits another 10sec period, tries to kill whatever might remain and successfully unmounts the directory. Interestingly, pam_mount won't wait after sending the last signal, so having kill is important for term to work well, otherwise there will still be a race. So it seems to me that the pam_mount processing happens a bit early during logout, before the system gets an opportunity to shutdown some of the user processes. Is there anything I can change in my configuration to let everything stop gracefully leaving the <logout ... /> as a last resort option for pam_mount?
