Hello all,

I'm having strange failures when creating files inside /mnt/utmp. Maybe someone has a clue? Here's the log:

Code:
~$ cd /mnt/utmp/pnd/usr/lib/opkg/info
~/usr/lib/opkg/info$ touch aa
touch: cannot touch 'aa': Input/output error
~/usr/lib/opkg/info$ sudo dmesg -c
[33061.744476] aufs au_lkup_neg:326:touch[21270]: I/O Error, info should be negative on b0.

this "info" directory exist in the RO part of the union but not in the RW side. Create it manually (outside of the union) to fix these IO errors :)
 
I don't think that's the root cause, because when this does work, I can remove the RW tree and redo the touch command, and the RW tree gets recreated again and again.

Anyway, I can't reproduce the error after a reboot, so unless someone knows what the error message means, I won't be able to deduce anything by trial and error.

That intermittent stuff is indeed annoying.
