Catalyst Help

[EEfw23]

Just for the sake of convenience, I will just start this thread so it will be easier to discuss any problems I might have and so more people can see it instead of "Creating a liveusb".

I am using catalyst to create a custom system with a fully graphical environment and some tools like libreoffice and firefox that I can use on any computer, I have set up my stage 1 spec file and I am having trouble when I run catalyst -f livecdstage1.spec with the USE changes. My question is How do I apply them ? and also Does anyone have any general suggestions about catalyst or spec files in general ?

Thanks in advance.

I have found the solution: Go to /var/tmp/catalyst/tmp/default/livecd_name/ , then go to etc/make.conf in THAT directory and add:
EMERGE_DEFAULT_OPTS="${EMERGE_DEFAULT_OPTS} --keep-going"
EMERGE_DEFAULT_OPTS="${EMERGE_DEFAULT_OPTS} --autounmask-write"

I am not sure that the --keep-going one is necessary.

then return to /var/tmp/catalyst/tmp/default/livecd_name/ and chroot to the install with:
mount --bind /sys sys
mount --bind /proc proc
chroot . /bin/bash --login
then run etc-update it gave me "nothing to do" or the like but just rerun catalyst -f livecd_name.spec and everything works!

Can someone help me with setting up a catalyst stage2 spec file please? I am having trouble with livecd/runscript and livecd/archscript. The supposed path for runscript is /usr/lib/catalyst/livecd/runscript/"script_name" but there is no runscript directory the same goes for the archscript. I get the feeling that the build hangs on rsync because I leave these fields blank. My catalyst version is 2.08.
