The following patch adds cramfs support to domU kernels so cramfs based
ramdisks can be used for initrds.

This is very useful for supporting an automated test system that uses
initrds (like the console testsuite). Thanks Sean!

To clarify further - you don't need to be root to make a cramfs initrd because
you don't need to loopback mount anything. This makes it rather more
convenient for developers who don't have root on their machines.

This reminds me a side problem I experienced.
x235:/tmp/xen-unstable.hg/linux-2.6-xen-sparse/arch/xen/configs # grep
CONFIG_REISERFS_FS=y *
xen0_defconfig_x86_32:CONFIG_REISERFS_FS=y
xen0_defconfig_x86_64:CONFIG_REISERFS_FS=y
xenU_defconfig_x86_32:CONFIG_REISERFS_FS=y
x235:/tmp/xen-unstable.hg/linux-2.6-xen-sparse/arch/xen/configs # grep
REISERFS xenU_defconfig_x86_64
CONFIG_REISERFS_FS=m
REISERFS has been turned on by default on all the config files except the
one for xenU on x86_64. Any particular reason for not turning it on for
xenU on x86_64? This sometimes causes problems when booting domU with
REISERFS as domU root fs. I have to build an initrd for it.
Thanks,
Li

To clarify further - you don't need to be root to make a cramfs initrd
