The line 414 is this?
AuDebugOn(!sbinfo || !list_empty(&sbinfo->si_plink));
If so, did you install /sbin/umount.aufs and others, or specify noplink
mount option?
(from aufs README)
----------------------------------------------------------------------
After 'make',
$ man -l ./aufs.5
# install -m 500 -p mount.aufs umount.aufs auplink aulchown /sbin
(recommended)
# echo FLUSH=ALL > /etc/default/auplink (recommended)
# insmod ./aufs.ko
$ mkdir /tmp/rw /tmp/aufs
# mount -t aufs -o dirs=/tmp/rw:${HOME}=ro none /tmp/aufs
If you don't install aufs helper script and don't setup
/etc/default/auplink, you should always set 'noplink' aufs mount option.
