BTW, correct me if I'm wrong, but a new signature (HFS has it at the first two bytes of its volume header) and a change to the function for comparing two Unicode keys (so it will compare them respecting case) is all that is needed to make a case-sensitive variant of HFS. Of course, the utilities (fsck_hfs in particular) should be changed, too. -- Yar To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
