[desktop-discuss] gnome-session crash

[Dave Miner]

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.
