Bug#701916: Kill local user processes on logout
Control: tags 701916 -pending +unreproducible I'm having trouble reproducing the problem on a fatclient... I've tried with icewm, LXDE, XFCE and GNOME, with a variety of applications open. None seem to linger after logout as a fatclient, and the homedir gets unmounted appropriately... Also tried with localapps, but couldn't reproduce the problem. Please provide more information about how to reproduce the problem when you get a chance! live well, vagrant -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".

Bug#701916: Kill local user processes on logout
Package: ltsp-client-core Version: 5.4.2-5 Severity: grave Tags: patch upstream LTSP fat clients and also thin clients that use localapps, mount /home/username with SSHFS and unmount it on logout. Unfortunately at the point where the unmount happens, local processes are still running, and when Xorg killed them later on, they end up writing their data to the local tmpfs filesystem because the SSHFS mount is no longer there. That's one reason for data loss (hence the grave severity), but there's another, worse one: On the next login of the same user, /home/username/ exist locally on the tmpfs, so the LTSP code thinks that the sysadmin has taken care to mount the user home dirs via other means (e.g. NFS), so the SSHFS mount is no longer needed. Thus, all user sessions after the first one, use a local tmpfs /home/username. Users don't see their existing documents or settings, and any new document they write, will be saved in the local tmpfs and lost on client reboot. Here's the upstream bug report: https://bugs.launchpad.net/ltsp/+bug/1093144 And the patch: http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/revision/2462 Only one file needs to be patched, client/localapps/ldm-rc.d/X99-zlocalapps-cleanup. -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
