Alright, here is what really happens:
INVOL puts some files on your disk when you run it.
ACL, if you go 'ACL * -all' where * is /, //, /sys, or 'node_data
will render your disk unmountable. This occurs with ACL from
9.5, 9.5.1 and, yes, 9.6.
Apollo will be sending you a letter telling you not to do this.
It is nor fixed in 9.6 as I had thought, seems its already production. SO
9.7 will be the one it gets fixed in. (9.7 is the one that you will
have to re-invol your disks to take advantage of the Berkely soft cylander
grouping)
DONT ACL -all, use edacl instead, its safe.
... Something to do with trash left on the stack.....

In particular, "//", "/", "/sys" and "/sys/node_data" Invol under 9.0 or 9.2.x creates file the same way as Invol for sr9.5 and sr9.6. >ACL, if you go 'ACL * -all' where * is /, //, /sys, or 'node_data >will render your disk unmountable. This occurs with ACL from >9.5, 9.5.1 and, yes, 9.6. The problem not guaranteed to show up. Actually, "ACL <sdir> -all" is SAFE, it justs report the current ACL. "ACL <sdir> /path -all" where path is any other directory, is where the problem is. The best workaround NOT to acl these dirs till you get the fix. You can acl the DIRECTORIES themselves, just not the initial default acls inside the directories. i.e. Acl "/" without p rights for the world and then noone can change the initial dir and initial file acls. >Apollo will be sending you a letter telling you not to do this.

EDACL is NOT safe... EDACl changes initial dir and initial file acls the same way ACL does. Joel p.s. Though they may seem to be, these are not the official words of Apollo Computer, those words will come in the letter to all customers.
