[PATCH 1/3] Config: Support rootfiles with spaces in filenames

[Michael Tremer <michael.tremer@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 2346 bytes --]

Our build scripts can't handle any spaces in filenames. This is being
fixed by this patch with only a slightly changed set of shell commands.
