Subject: Support template parameters in overlay directory. For now only
X-Git-Url: https://git.grml.org/?p=grml2usb.git;a=commitdiff_plain;h=ae3d73f2caee267480ebfe283dd4a08e92f1c5b5

Support template parameters in overlay directory. For now only
GRML_NAME, VERSION RELEASENAME DATE SHORT_NAME and BOOTID are supported.

As in grml-live grml2iso supports template filename as well which you will need
for modifying file entries.
