Somebody trying to use unionfs in 2.2! ;-) // // Seriously, that's not the only panic you're going to get if you try to // use that code in that branch. AFAIK, it's really only going to be a // practical option for 3.0 unless someone back-ports all the changes // which were necessary to make it truly work in -current. Indeed, last week I thought of using umapfs, just to find all problems above. :( I was planning a scheme to allow use of ffs zip disks in my machines, without having to allow userids to be seen. BTW: This made me think of a umapfs with a command line "one-userid-only" option, to avoid creating a umaptable file. I would even try to do that myself, but I have currently no developing access to a -current machine (pun intended). What do people think of that idea ? Is it worth to give it a try ? Jonny PS: Why ffs zip disks ? Because msdosfs is TOOOOOOOOO slow :), and sometimes it makes my system freeze (I'm searching for causes, but found no real clue yet). PS2: How is VFS code going -current ? Much better than in -stable ? -- Joao Carlos Mendes Luis M.Sc.
