GNOME is mounting the temporary loopback devicemapper filesystem, interfering with livecd-creator and causing it to fail.

DavidZ says we need to launch things via devkit-disks to avoid this.

devkit-disks --inhibit -- /bin/foo

Comment 1 Warren Togami 2009-03-05 22:30:19 UTC

Bug #488850 devkit-disks --inhibit broken parameter handling

Comment 2 Jeremy Katz 2009-03-06 16:36:53 UTC

While this might work around the problem, it introduces new and different problems
1) Someone plugs in a USB device while their livecd build is running.  Now their USB device doesn't get mounted
2) Everything that we've done to have "nice" handling of ctrl-C is thrown out the window.  Entirely.  Forget cleanup.  

Really, this whole "inhibit a subsystem" thing is nothing more than a large hack that we really need to have a better solution for :/

Comment 3 Jeremy Katz 2009-03-20 17:48:51 UTC

Okay, new DeviceKit-disks (003-7.fc11) fixes this by not automounting all dm devices
