Ok I noticed I tested this wrong :(


fz:/boot# dpkg --compare-versions 2.6.26-1-amd64~rc1 gt 2.6.26-1-amd64~rc1~git1 ;echo $?
0
fz:/boot# dpkg --compare-versions 2.6.26-1-amd64~rc1 gt 2.6.26-1-amd64~rc1-git1 ;echo $?
1

So i think it works if there is only 1 ~ instead of 2

Unfortunately I'm not that good in regexp but I try to figure out how this can be done:

-git -> ~git
-rc -> ~rc
-rcN-git ~rcN-git
