I've got only one partition in my image file:
$ /sbin/parted alan_restore.img
WARNING: You are not superuser. Watch out for permissions.

I'd expect I should refer to it with /dev/sda1. However, when booting it
doesn't find it.
It's strange, since it finds /dev/sda, i.e. the entire disk:
[ 6.438693] sd 0:0:0:0: [sda] 188743680 512-byte logical blocks:
(96.6 GB/90.0 GiB)

[ 6.482421] sd 0:0:0:0: [sda] Write cache: enabled, read cache:
enabled, doesn't support DPO or FUA
However, it then complains that /dev/sda1 does not exists:
[ 39.409892] blk_update_request: I/O error, dev fd0, sector 0
[ 39.410232] floppy: error -5 while reading block 0

Gave up waiting for root file system device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/sda1 does not exist. Dropping to a shell!
Same thing if I try with /dev/sda2 or anything.
