I'm trying to add XFS and ReiserFS to CentOS, integrating with Kickstart. I think I'm fairly close. I've added xfs.ko and reiserfs.ko to modules.cgz in initrd. Several of my partitions now specify --fstype=xfs. I can see tty5 mkfs.xfs is creating the XFS file systems. The system currently installs completely via kickstart, but it does not mount the XFS file systems while in the kick process. /mnt/sysimage/etc/fstab is populated correctly. In tty2, lsmod does not show that the xfs module is loaded (ext3 is in the list). I tried loading it manually with modprobe and insmod but I don't think it's loading (no error message at all -- no error). BTW, as with Fedora, I also specified 'xfs' as an option to syslinux/pxelinux. What else am I missing? Thanks for any help.
