Well, there is a big question - is there in the patchset a "hostfs" or "externfs" patch? In that case, if you used the *new* hostfs code, everything I said disappears, because that's completely different code. Only in the other case, you can find below my answer. > I just used > mount /root/UML/a /a/lost+found -t hostfs Hmm, like I supposed. This is the wrong command line. To mount the host /root/UML/a, you need to use this syntax: mount none /a/lost+found -t hostfs -o /root/UML/a This is the correct syntax. > why should you need an -o ? The mount-point works, and everything inside > it looks like it should, Well, do you claim that it contains only the content of /root/UML/a on the host? I think that this is false, and I just tested this on my UML (2.6.9-bs5): [EMAIL PROTECTED]:~ (0)# umount /mnt/host/ [EMAIL PROTECTED]:~ (0)# mount /bin/ -t hostfs /mnt/host/ [EMAIL PROTECTED]:~ (0)# ls /mnt/host/ bin/ dev/ etc/ lib/ opt@ root/ sys/ usr/ boot/ disk@ home/ mnt/ proc/ sbin/ tmp/ var/ [EMAIL PROTECTED]:~ (0)# umount /mnt/host/ [EMAIL PROTECTED]:~ (0)# mount none -t hostfs /mnt/host/ -o /bin [EMAIL PROTECTED]:~ (0)# ls /mnt/host/ Mail@ df* install* pidof@ tar* [EMAIL PROTECTED]:~ (0)# umount /mnt/host/ Satisfied? If that syntax works on your kernel, something *very* strange is happening. > and files I put into it appears as they should (I > used that directory, since the uml-filesystem is just banged together som > files from /bin so I could fix a disk, use /bin/sh as init for instance) > An those entries as what likes in /proc/mounts, since I don't have a > maintained /etc/mtab file in that filesystem. /etc/mtab is symlinked to > /proc/mounts Ok, understood, but the duplicate entry still seems a bit strange... -- Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
