Strange... I just checked again for this behavior after rebooting, and everything is working correctly. At least one other SLAX user has seen this behavior. If nobody else has seen this, it could be some interactions with SLAX's POSIX overlay or squashfs code. I was using an XFS filesystem for my persistent writeable directory. What can I check the next time I see this behavior? My aufs is compiled with AUFS_DEBUG=y. Does the debug info all go to 'dmesg'?
