My mistake I misread your statement in email 0. You said that squashfs
has real inode numbers and that cramfs didn't. Good luck with your
mainlining attempt. Once you get xattr support this would definitely
make life better for people who want to make SELinux enabled LiveCDs and
other small devices.
