Спасибо за оперативный ответ.
Кто-нибудь знает почему bacula в AUR перенесли?
Aivar, спасибо за ответ. Так что мне нужно сделать чтобы оздать файловую систему на диске?

Arch не видит чистый dvd-r диск. Если взять диск и записать что-нибудь на него, то диск становится виден.
udisks –mount /dev/sr0:
Mount failed: Error mounting: mount exited with exit code 18: mount: /dev/sr0 is write-protected, mounting read-only
Error opening '/dev/sr0': Read-only file system
Failed to mount '/dev/sr0': Read-only file system
udisks –mount /dev/sr0 –mount-options=ro
Mount failed: Error mounting: mount exited with exit code 12: Failed to read bootsector (size=0)
Failed to mount '/dev/sr0': Invalid argument
The device '/dev/sr0' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
