To install alpine linux on a dedibox SC, start in rescue mode, connect to the box and run the following script as root:

#!/bin/sh

set -ex

CHROOT

printf 'root:%s\n' "${PASSWORD}" | chroot /mnt /usr/sbin/chpasswd

umount $ROOT/proc
umount $ROOT/dev
umount $ROOT/sys
umount $ROOT

Then restart the box into normal mode.

Thanks a lot to uggedal and sin for their help with this.
