Re: [Squeeze]: install with lvm partitioning

[Rino Del Campo <gennaro.delcampo@brain-debug.org>]

Hi folks,
I found a solution!

I have installed debian from d-i with kernel and initrd from stable branch.
As mentioned in previous email, I got several error messages.

After partinioning I performed the following steps:

(1) open a connection with d-i in shell mode

(2) chroot in target filesystem:
        # mount -o bind dev /target/dev
        # mount -t proc none /target/proc
        # mount -t sysfs none /target/sys
        # chroot /target /bin/sh

(3) create an init-top script in initrd called dasd (as indicated in
http://lists.debian.org/debian-s390/2011/02/msg00017.html):
        # cat > /etc/initramfs-tools/scripts/init-top/dasd <<EOF
#!/bin/sh

PREREQ=""
prereqs()
{
    echo "\$PREREQ"
}
case \$1 in
# get pre-requisites
prereqs)
    prereqs
    exit 0
    ;;
esac

for x in \$(cat /proc/cmdline); do
    case \${x} in
        dasd=*)
            modprobe dasd_mod dasd=\${x#dasd=}
            ;;
    esac
done
EOF

(4) allow exec permission on dasd file
        # chmod +x /etc/initramfs-tools/scripts/init-top/dasd

(5) create zipl.conf
        # cat > /etc/zipl.conf <<EOF
[defaultboot]
defaultmenu = menu

:menu
target = /boot
1 = debian
default = 1
prompt = 1
timeout = 3

[debian]
target = /boot
image = /boot/vmlinuz
ramdisk = /boot/initrd.img
parameters = root=/dev/mapper/system-root dasd=0.0.0100
EOF

(6) rebuild initrd
        # update-initramfs -v -u -k 2.6.32-5-s390x

Afterwards, completing the remaining steps, the d-i regularly installs zipl on
mbr.

This time the system is bootable.

Regards,
Rino
