Debugging - turning off progress bar

[Philip Rhoades]

People,

I am having some issues building isos.  I can build a minimal iso that 
boots to a prompt but only have a base iso getting to the end of the 
progress bar and then hanging - is there some way of turning off quiet 
mode and the progress bar so I can what the problem is?

Thanks,

Phil.

Are you talking about the plymouth progress bar?  You can simply press
"ESC" to kill the progress bar while it is running.

Isolinux and most other bootloaders let you edit the boot parameters;
just delete "quiet" and "rhgb" there at boot time. None of the above
is livecd specific.

If you want to make this the default on images you build
then just add the following line in the %post --nochroot section:

sed -i -e '/ *append / { s/quiet// ; s/rhgb//;  }' 
"${LIVE_ROOT}"/isolinux/isolinux.cfg

With USB media created with live-iso-to-disk you can even edit this
file later on the stick itself.

Yep, I usually do this after the install - didn't even think of it for 
this . .
