[Bug 38650] Nautilus DVD burning may fill up drive

[John Moser]

Public bug reported:

Affects: nautilus-cd-burner libnautilus-burn3 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
On a default Ubuntu install, /tmp is on /.  If / is sufficiently small
(mine is 6.0 gigabytes), burning a DVD may fill up /.

This seems to be a difficult issue to resolve.  Here are a few thoughts.

 - Although most default Ubuntu installs place /home on / and thus allocate the largest portion of the drive to /, this does not preclude the drive from filling up.  My /home used to be a 60GB partition, I filled it.  It is now 90GB and 80% full.  A user with a large drive may still run into this issue.
 - Using a separate /tmp would take space away from /home or /, largely as a waste.
 - Using a tmpfs on /tmp is impossible; the tmpfs will fill up and the system will fall into swap thrashing
 - Building the image on the fly may fail.  An option to do this in nautilus would be useful, however; drives on separate IDE busses (primary/secondary) or SATA drives will have little to no trouble keeping up.  Nautilus should activate buffer underrun protection if this is done, so that the recording speed reduces automatically if the buffer can't be kept full.
