Hello Everyone
I'm new to Linux and to Buildroot.
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?
BR,
Tal

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

Hi Thomas
Thanks for your reply.
So how can I check this kind of compressed file system (.ext2.gz)?
Is it the same for other file systems?
BR,
Tal

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.

Hi Julian
How can I do it if it is the rootfs?

I don't see your point, rootfs.ext2 _is_ your rootfs
(ext-filesystem-image).
What do you mean by "check"?
