[PATCH 2/2] partresize: enable journal on ssd's and vm's

[Arne Fitzenreiter <arne_f@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 1384 bytes --]

the flashimage is build without journal to not destroy
usb thumbdrives or sd cards. On real ssd's and virtual
machines it should enabled for higher data security.

So this patch add the journal is drive support smart.
