I tryied this metod but faced several problems:
dd if=/dev/sda skip=$((8192*8+1)) bs=64 count=$((0x$(dd if=/dev/sda skip=$((8192*128+3)) bs=4 count=1 2>/dev/null|hexdump -ve '/1 "%02x"')/64+1)) | zcat > initrd
gzip: stdin: not in gzip format
I'm not sure is it ok?
mount -o loop initrd rootfs
mount: you must specify the filesystem type
But before that I had to do this:
mknod /dev/loop3 b 7 3
because without this i had and answer that "no loop device is available".
And basicly thats the place im stuck
mount -o loop initrd rootfs -t ext2
but it also didn't work
