I'm having problem using GRML_LIVE_SOURCES to specify a third party repo,
namely debian-multimedia. Many attempts have been failed, and the last one's
cause is beyond me. Is it because:
W: Duplicate sources.list entry...
Moreover, which file in chroot does GRML_LIVE_SOURCES affects? I've checked
but none seems to contain my setting.
