Bug#291232: kernel-source-2.6.10: Cannot burn DVD as normal user
Package: kernel-source-2.6.10
Version: 2.6.10-4
Severity: important
Tags: patch
When running as normal user with kernel 2.6.10, growisofs gives the
following error when attempting to burn a DVD:
Executing 'builtin_dd if=/dev/fd/0 of=/dev/hdc obs=32k seek=0'
:-( unable to PREVENT MEDIA REMOVAL: Operation not permitted
Running as root works fine.
I found this patch on LKML, and can now burn as normal user:
