[Bug 178774] Re: Silent failure when out of /tmp space

[Tristan]

I decided to take a deeper look into it, and it looks like it's not
gnomebaker's fault; it's cdrkit's fault. Should this bug be filed
elsewhere?

`readom` will detect the error, but it returns a success error code. I
wrote a quick sh script wrapper to return a failed exit code. gnomebaker
picks it up and reports a failed copy.

Here's what I did to test readom:

$ mkdir /tmp/tmpfs
$ sudo mount -t tmpfs -o size=10M,mode=0777 /dev/null /tmp/tmpfs
$ readom dev=/dev/sr0 f=/tmp/tmpfs/test.iso
