Package: initscripts Version: 2.88dsf-43 Severity: normal Dear Maintainer,
Normally, the mount-functions.sh mounts /run, /tmp, etc as tmpfs filesystems. To signal this fact to the other bootscripts, it creates a ".tmpfs" file inside. However, when the mounting fails, and the corresponding filesystem has thus _not_ been turned into a tmpfs, the .tmpfs file is still created. In my case, this happened inside an lxc container. Because the mounting capability was dropped for the container, mounting /run failed. However, since .tmpfs was still created, the bootclean logic did not run, making my container run with a dirty /run, causing all kinds of problems. I looked at making a patch that made domount return a failure if the (re)mount failed and made the mount_* functions only create .tmpfs files if the mount succeeded. However, I ran into two problems: - Currently, .tmpfs is also touched when the filesystem is only remounted, which probably doesn't make sense in the first place? - When there is already a mountpoint (e.g., /run mounted by initramfs), no mounting happens. I'd say this should make domount return failure and prevent creating .tmpfs. However, looking at the initramfs code, it seems that it mounts a tmpfs on /run but does _not_ create the .tmpfs file, so if mount_run doesn't create it, it will never be created in the initramfs case... I wonder if it makes sense to actively check if /run (etc.) is a mountpoint and look into /proc/mounts (or whatever is the best way for this) to see if it is a tmpfs? Then this could just happen after the mount and it doesn't matter if the mount failed or succeeded, or if the filesystem was already a tmpfs to begin with. Does that make sense? Gr.
