-no-progress appears to be the option to mksquashfs that you are looking 
for.  I too have been annoyed by its output in a logfile.

I thought about throwing together a patch to finally implement some kind 
of --verbose/--debug/--quiet to livecd-creator.  But I'm not exactly 
sure where the progress bar falls into that.

Perhaps the correct way would be to somehow detect if the livecd-creator 
output is going to a terminal, and only do the progress bar in that 
situation.  I know this is possible, as a bug I had in cleanupDeleted 
dealt with the fact that fsck (in the absense of a flag) behaved 
differently based on whether or not the output was redirected.
