Okay, I've got a big FFS partition I'm trying to share between FreeBSD-current and Solaris/x86, which sounds like a recipe for trouble, I know, but it seems to be working well (assuming you fsck thoroughly when you switch to the other OS), except for one big problem, thanks to Solaris 2.5's ACL implementation. Every time I boot into Solaris, its fsck gives a bunch of "I=xxxx BAD/CLEARED ACL (FIXED) I=6846" errors. Then when I look at any directory owned by myself (UID 6846), I find that many of them have switched to 000 permissions, so I have to chmod lots of stuff before I can even use it! Now, can some filesystem guru (Terry?) who maybe knows how Solaris is implementing ACL's tell me if it would be feasible to patch FreeBSD's FFS implementation to insert some null ACL entry in order to keep Solaris happy? Perhaps this is stored in the 30 bytes of the inode "for future expansion", and maybe we can put different values there. It's interesting that my little hack has been as successful as it has, since neither OS was designed for filesystem compatibility with the other, but I assume this is because Sun needed to keep Solaris UFS at least reasonably backwords compatible to SunOS for the SPARC version. BTW, this filesystem was built with "newfs -O" to use 4.2/4.3BSD compatibility mode. ---Jake
