Package: aufs-modules
Version: 2.6.26-1

As several bug reports in Debian and my own experience show, AUFS in Debian Lenny is badly broken.

It does work standalone, but as soon as nfs or samba or some other file system gets involved, it does segfault if called from init and give other error messages when called later from shell.


A stack trace from init can be seen in bug # 510573 which is not resolved.

When called later from a shell, the following errors have been observed:

[ 713.236312] aufs au_xino_create2:622:mount[2942]: .aufs.xino create err -2 [ 713.240116] aufs au_xino_set:1139:mount[2942]: I/O Error, failed creating xino, forcing noxino (-2). [ 753.520607] aufs test_add:367:mount[2960]: uid/gid/perm /s_ro 0/0/0755, 0/0/0777

[ 821.521755] aufs test_add:367:mount[3010]: uid/gid/perm /s_ro 0/0/0755, 0/0/0777 [ 822.486718] aufs au_xino_create2:622:mount[3010]: .aufs.xino create err -2 [ 822.499927] aufs au_xino_set:1139:mount[3010]: I/O Error, failed creating xino, forcing noxino (-2).

The developper of aufs writes that it is better to use newer versions of aufs2, but imho Lenny should provide a stable solution usable with vanilla kernels.

This bug prevents using aufs  for tft booting in combination with aufs.
