At the risk of reporting further bugs :-) here it goes:
=======================================================================
1)
Something I've recently reported to the e-mail address listed
on the mkudffs manpage:
...a small problem with mkudffs, as obtained from
udftools-1.0.0b3-7.fc6.
The problem is as follows: if I take a new DVD-RAM, create (say)
an ext3 filesystem, and some time later I run mkudffs over it,
then when I try to mount it the disk still seems to remember
about having had a previous filesystem.
What I mean is that mount may succeed if one specifies the newer
filesystem, at least if no files have been copied yet, and also
succeed with the older filesystem.
Here is an example, for the same disk(!) without any formatting
nor copying in between (note also the dates)
# mount /dev/scd0 /mnt/dvd -t udf
# ll /mnt/dvd/
total 4
drwxr-xr-x 3 root root 92 2007-11-21 18:34 ./
drwxr-xr-x 13 root root 4096 2007-09-03 17:27 ../
drwxr-xr-x 2 root root 40 2007-11-21 18:34 lost+found/
# umount /mnt/dvd
# mount /dev/scd0 /mnt/dvd -t ext3
# ll /mnt/dvd/
total 24
drwxr-xr-x 3 root root 4096 2007-11-21 19:29 ./
drwxr-xr-x 13 root root 4096 2007-09-03 17:27 ../
drwx------ 2 root root 16384 2007-11-21 19:29 lost+found/
Eventually I found that I could erase the (or at least part of the)
information that remained from ext3 by using fdisk to set a filesystem
of type "0" ("empty") and then running mkudffs over.
That is not very practical of course, and I am also not completely
sure that no other outdated info remains on the disk.
=======================================================================
2)
With 2.6.24-rc1-git10 (did not see it with other kernels yet)
# find /proc -name cdrom
/proc/sys/dev/cdrom
find: WARNING: Hard link count is wrong for /proc/net: this may be
a bug in your filesystem driver. Automatically turning on find's
-noleaf option. Earlier results may have failed to include
directories that should have been searched.
=======================================================================
3)
While I am at it, here's a suggestion. One of my DVD-RAM disks
had apparently some (likely minor) problems, because I've just
found the following notice in /var/log/messages :
... kernel: EXT3-fs warning: mounting fs with errors, running
e2fsck is recommended
This message appears 11 times in that file. I've never seen it
displayed on an xterm, although I always mount the disks "by hand",
on the command line!
The request/suggestion is (obviously) please send that message to
syserror too!!
=======================================================================
Which other logs should I look at?
Best regards
Paulo
