There was a fatal bug in AUFS, but it was fixed at 08/08, so in the 15/08
snapshot AUFS should be OK. But I remember an unresolved similar error on a
Solaris 8 x86 box some times ago. After latest fixes I don't have tried if
it now works.
So, no ideas ... But in next weeks I will try again on Solaris.

Guido
