Mount Linux image file

[Victor Dorneanu <victor%dornea.nu@localhost>]

Hi port-xen!

I have finally managed it to install Debian (over network) into a
image/container file.

$ file root.img
root.img: x86 boot sector; partition 1: ID=0x83, active, starthead 1,
startsector 63, 1445787 sectors; partition 2: ID=0x5, starthead 0,
startsector 1445850, 208845 sectors

I was told I should use "vnconfig" in order to mount the partitions:

$ vnconfig vnd0 root.img
$ disklabel /dev/vnd0
# /dev/vnd0d:
type: vnd
disk: vnd
label: fictitious
flags:
bytes/sector: 512
sectors/track: 32
tracks/cylinder: 64
sectors/cylinder: 2048
cylinders: 812
total sectors: 1664000
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0           # microseconds
track-to-track seek: 0  # microseconds
drivedata: 0

9 partitions:
#        size    offset     fstype [fsize bsize cpg/sgs]
 d:   1664000         0     unused      0     0        # (Cyl.      0
-    812*)
 e:   1445787        63 Linux Ext2      0     0        # (Cyl.     
0*-    705*)
 i:    208782   1445913       swap                     # (Cyl.   
706*-    807*)
disklabel: boot block size 0
disklabel: super block size 0


Everything looks fine by now. However I can't mount the ext2-partition
to extract the kernel.

$ mount -t ext2fs /dev/vnd0e /mnt
mount_ext2fs: /dev/vnd0e on /mnt: incorrect super block


Any ideas?!
