Package: grml-rescueboot
Version: 0.4.5
Severity: wishlist
Tags: patch
Hi,
This package is very useful. However, upon install one has to go
download a grml iso image, and then keep updating it periodically.
I have done a small script that queries the grml site for release
images, and downloads the latest. It is possible to specify the
architecture (32/64/96 with autodetection) and the version (small/full).
I am not sure this script ready for direct usage, especially as it lacks
any kind of documentation. But it could be useful shipped as an example
script.
