I usally use ext4 as filesystem.

# lsmod|grep ext
ext3                  100768  0
jbd                    39586  1 ext3
ext2                   49572  0
ext4                  263621  1
crc16                   1255  2 ext4,bluetooth
mbcache                 4450  3 ext2,ext3,ext4
jbd2                   48679  1 ext4

Isn't great what an initramfs can do?
