Fine with me. Big userids dont work on "ancient" systems, either (e.g.,
the AMigaOS "BFFS" version 1.3 would damange netbsd-1.1 and later filesystems
as it only understood newfs -o filesystems). If you want to mount a ACLed
filesystem image, use an ACL kernel. If you want to share a medium with 
an old system don't ACL its filesystem. There are bigger security problems
with carrying filesystems around than ACL availability; you'd need encrypted
files for that IMO.
