Hallo,Just to let know to the list, I have a 8.3 liveCD and PXE buildI generated an ISO, which should be usefull in case you need to fix your LFS.I would like to learn how to build a LiveCD. I tried with squashfs myself but I could never get it running. Could you elaborate please? Or point to some nice instructions? Tschau...Thomas
The best I can do is to provide you with an extract of the
Makefile sequence. That will give you "my" way to do it.
Caution: ISO building is relatively easy because I am
using YUM and RPM (yum install packages_list)
Hoping you can use it as frame example for your ISO.
