[PATCHv2 04/12] installer: Ensure to always create the /boot directory.

[Stefan Schantl <stefan.schantl@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 1165 bytes --]

Ensure to always create the /boot directory during the mounting
of the various created file systems. If the /boot directory does not
exist some following mount operations could not be performed correctly
and the installation/mounting will fail.
