Bug#506074: pmount: mounts device with wrong uid and gid
I experimented a bit more and the bug was indeed caused by pmount and gnome-volume-manager deferring the mounting process to mount. Then mount was blindly following the uid and gid stored on the DVDs. Once the /etc/fstab line is removed, pmount and g-v-m take over and they forcibly set the uid and gid of the files, hence hiding the flaws of the DVDs. There is still a bug/feature somewhere else (in debian-installer perhaps?), as the /etc/fstab line was added by software. (I would never have called a mount point cdrom_0_ and added symlinks all over the place.) But that is a story for another time and report. Sorry for the noise, I should have been a bit more careful.

If you have gnome-volume-manager = 2.22.1-1 (which is probably the case according to your pmount version), nautilus shouldn't use pmount. Hmmm... Could you elaborate a bit more ?

I'm waiting for a debug output in the case it fails, but in the meantime, I'm downgrading this bug, as it might not be a pmount bug at all... Now that I think about it, by any chance, did you not burn the DVD with the genisoimage -R option rather than -r ? (or you didn't burn the DVD at all) ? And when you say it is uid=501, gid=20, is that ls telling you that, or mount ? (that is a big difference). If only ls says it, and not mount, your DVD was not burnt properly. In any case, it should be readable by all, shouldn't it ? If not, then it really was burnt crappily... Cheers, Vincent -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

As for mount, it does not say anything, but I have yet to test again with the DVD. Note that this is a DVD with an UDF file system, so I don't know how relevant genisoimage may be. That being said, your mail prompted me to look whether UDF has a similar feature. It does: The UDF superblock contains a uid and a gid which applies to all the files of the DVD. One has to use the option uid=forget when mounting a DVD to avoid that. I will report later whether or not it fixes the issue.
