Debian on an external storage #1

Is it possible to install debian on an USB drive to use all the disk space on the NAS?

vzhilov commented 4 years ago

Yes, sure.

I believe the USB drive will be detected as /dev/sdc1 and then last lines of /initrd/init will be:

mount -o rw /dev/sbc1 /mnt/root 2>&1 >/dev/null
if [ -h /mnt/root/sbin/init -o -e /mnt/root/sbin/init ]; then
  boot
else
  rescue_shell
fi

Internal RAM of the NAS will boot, then it will decrypt the NAS and then turn the further booting over to Debian on USB drive

Thanks for the working information. After correcting the small typo I could successfully start from /dev/sdc1. 

mount -o rw /dev/sdc1 /mnt/root 2>&1 >/dev/null
if [ -h /mnt/root/sbin/init -o -e /mnt/root/sbin/init ]; then
  boot
else
  rescue_shell
fi

I have also evaluated another approach that is more flexible and does not rely on hard-coded /dev/sdX1 drive specifications. After further testing I will hopefully be able to release it soon.

I have changed the init script adding a little dialog with a boot option from external device

Hello! Thank you for the great work. How can I set the boot to default, or permanent to /dev/md1? It is asking me everytime to choose. Thank you, Regards Rainer
