I've succeeded to build a kernel and a file system (.ext2) and to test it with QEMU. Now I'm trying to use a compressed file system (.ext2.gz) but it will not load (kernel panic). How should I load a compressed file system which is the rootfs?

If you use this filesystem as a hard disk image, i.e the '-hda rootfs.ext2' Qemu option, then it has to be uncompressed.

So how can I check this kind of compressed file system (.ext2.gz)? Is it the same for other file systems?

As far as I know: You'll need to uncompress it, after that you can loop-mount it, so: sudo mount -o loop rootfs.ext2 mountpoint If you check with 'mount' afterwards, you should see sth. like this: ... /dev/loop0 on mountpoint type ext2 (rw) avfs (http://avf.sourceforge.net/) might work with compressed image, not tested though.
