patch to allow MINIX to boot from ext2.
To create a setup with MINIX on ext2, follow these steps:
- Assumptions:
- there exists a primary partition c0dApB with a MINIX installation
with GRUB support (/boot/image_latest exists on /dev/c0dApB)
- there exists a free primary partition c0dCpD
- Create an ext2 filesystem on c0dApB (from Linux, until Tthom
has ported mke2fs)
- Follow these steps (from a MINIX CD with ext2 support, another MINIX
installation (not c0dApB) or Linux >= 2.6.35):
mkdir /mnt/mfs /mnt/ext2
mount /dev/c0dApBs0 /mnt/mfs
mount /dev/c0dApBs1 /mnt/mfs/home
mount /dev/c0dApBs2 /mnt/mfs/usr
mount /dev/c0dCpD /mnt/ext2
synctree -f /mnt/mfs /mnt/ext2
echo root=/dev/c0dCpD > /mnt/ext2/etc/fstab
(note: no subpartitions used because that would confuse an unmodified
bootloader)
- Add the new MINIX installation to GRUB according to steps 7&8 in
