So, is linuxrc ready today to run from a squashfs? I was thinking about a code flow like this: modprobe squashfs modprobe loop mkdir /.tmpfs mount -t tmpfs tmpfs /.tmpfs mkdir /.tmpfs/initrd mv /image /.tmp/image mount -t squashfs -o loop /.tmp/image /.tmp/initrd symlinkfulltree --from /.tmp/initrd --to /.tmp rm -rf /* cd /.tmp exec chroot . linuxrc or similar. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
