Public bug reported:
Binary package hint: libblkid1
In karmic, my camera phone fails to automount when I plug it in via usb. This
works in hardy. I think I have tracked this down, via reading the mount
manpage, to the fact that mount cannot autodetect the filesystem type. Plugging
in the device, dmesg shows the partitions on the device correctly:
dmesg | tail

[ 6537.312180] sd 8:0:0:0: [sdb] Attached SCSI removable disk
However, this does not automount. If I try mounting manually, it fails:
sudo mount /dev/sdb1 /mnt/t
mount: you must specify the filesystem type
If I specify the filesystem to be vfat, no problems.
Reading the mount manpage, it tries to detect the filesystem type by using
blkid and vol_id. In Hardy and Karmic, blkid does not detect the filesystem
type:
sudo blkid -p /dev/sdb1
milli:~$ echo $?
2
Return code 2 from blkid, means "I don't know what filesystem that is".
However, vol_id, which is no longer available in karmic, detects it and mount
can automatically detect the and mount the device in Hardy:
hardy:> sudo vol_id /dev/sdb1
ID_FS_USAGE=filesystem
ID_FS_TYPE=vfat
ID_FS_VERSION=FAT12
ID_FS_UUID=BABE-BABE
ID_FS_UUID_ENC=BABE-BABE
ID_FS_LABEL=
ID_FS_LABEL_ENC=
ID_FS_LABEL_SAFE=
So it seems that blkid has been broken/incomplete for quite some time,
but mount was working by using vol_id. Since vol_id is now gone,
automounting of my camera phone is now broken.
Hope this is enough info, let me know if you need more.
