newly created partition not found in /dev/

[Lem]

Expected: sda1 + sda2 in /dev

Problem: Only sda2 is available. sda1 listed by most tools (lsblk, cat /proc/paritions, ...) but not found in /dev

Background: Using a fresh harddrive-image via virtualbox

Please ignore the fact that I did not format the luks-container on sda2, same problem would appear even if it would be formated.

[itoffshore]

A partition cannot be mounted if it does not contain a filesystem. I will add a check for mounting an unformatted partition.

You cannot run ls on an unmounted device (even if it had a filesystem).

setup-disk correctly detects the boot device is not mounted & exits.

[Lem]

I know that I can't list the content of a device with ls $DEV. My intention was to show that the new created partition sda1 is not accessible via /dev. Even if it does not contain a file-system the partition should be shown as a device.
