I have a server xbox with plain gentoo on it and its installed alright. I want to put a linuxroot 4 gig file system on my other xbox for music and torrents. I made the swap file and the linuxoot already. all i need to do is make a initrd to boot the linuxroot off of the fatx.
Shallax can you give me some help?? Or anyone else. I know how to use the mkinitrd file, but i dont know what modules i need, remastering it, etc.
Thanks
look inside initrd.gz

Yes it would be nice to know exactly how to recreate initrd.gz etc Unfortunately I don't.
Of course you can take a peek inside, and that may help... its as far as I have got on the subject.
As root:
Code: Select all
cd
mkdir unpack
cd unpack
cp /mnt/fatx/e/initrd.gz .
gunzip initrd.gz
mkdir mnt_initrd
losetup /dev/loop/1 initrd
mount -t ext2 /dev/loop/1 ./mnt_initrd
cd mnt_initrd
ls
Look around to your hearts content... then later:
Code: Select all
umount ./mnt_initrd
losetup -d /dev/loop/1
The above was done on an gentooX home install that has a /dev/loop/0 used already for the rootfs. YMMV.

Or quicker still...
Code: Select all
mkdir /mnt/tmp
gunzip ./initrd.gz
mount -o loop initrd /mnt/tmp
look around
Code: Select all
umount /mnt/tmp
gzip ./initrd
rm -rf /mnt/tmp
