Package: autofs Version: 5.1.8-2+deb12u2 automount has code (duplicated in various places in daemon/spawn.c) to pass the -n option to mount and umount when /etc/mtab is a symlink to either /proc/mounts or /proc/self/mounts . Despite this, I'm still seeing this in the logs:
Unable to update the mtab file, /proc/mounts and /etc/mtab will differ I think the problem is that autofs only checks for absolute symlink targets whereas Debian sets up /etc/mtab as a relative symlink (to ../proc/self/mounts on all the installations I've checked).
