I finally did sort out the problem below, just for the archives. fc-cache wants to write a fonts.cache-1 file in each directory referenced in the font directory list in /etc/fonts/fonts.conf. Since the Live DVD has a read-only /usr, this doesn't work, and it ends up creating a .fonts.cache-1 in root's home directory. Applications attempt to use that and crash as shown below; I could reproduce it just trying to run gedit under CDE
The workaround/fix is to run a chroot'ed fc-cache in the image construction process when the filesystem is writable. Anyone tested whether this stuff works right with a diskless client? They also mount /usr read-only and would seem to have the same problem.
