Hi Stephen,
That's interesting.
If you boot without nofstab option, the livecd bootup script scans your hard
disks and puts an entry
for each partition it can mount into /etc/fstab. This feature is not essential
for the functionality
of the livecd. In fact, I don't know why this should break things later in the
bootup script, when
your are asked to provide a password. Maybe your USB DVD-ROM confuses the
bootup script?
Solution: Just boot the livecd with "linux nofstab".
If you want to debug this, you can execute some parts of the bootup script
(/etc/init.d/runlast)
manually after booting the livecd.
For example, scan for partitions:
. /livecd/live/liblinuxlive
list_partition_devices
Or you can run the bootup script /etc/init.d/runlast once again without the
nofstab option:
edit /etc/init.d/runlast and comment out the line
# NOFSTAB=$( cmdline_parameter nofstab )
Now run the script manually
/etc/init.d/runlast
or even run the script in bash debug mode
bash -x /etc/init.d/runlast
Cheers,
Urs
