There still seems to be no solution to the problem az_ua describes in the previous posts:
- ISOs generated with tazlito out of Live, Core or GTKonly panic on boot-up
- ISOs generated with tazlito out of JustX boot without a problem
In the latest version of tazlito there's now an "umount" ahead of the eject command, which solves the problem with the failing auto-eject after generating the ISO image. But there are still other problems which are related to this. Burning or blanking CDs fails for the same reason. It seems, every CD that's loaded gets instantly mounted which prevents wodim from doing its job. In Live, Core or GTKonly the PCManFM configuration could be responsible for the auto-mounting of loadad CDs. But as the problem also occurs in JustX there has to be some other process which mounts the CDs. The solution would be to either prevent CDs from being auto-mounted or to put an "umount" ahead of any process that stumbles over a mounted CD.
In SliTaz 3.0 CDs were not auto-mounted. Even the system CD wasn't mounted after boot-up and tazlito would only temporarily mount the system CD to pull in some stuff needed for the new ISO. But SliTaz 3.0 was using hal and things are different now. Still, if this is possible, I think it would be generally better not to auto-mount CDs.
