2.6.8 release

[Andres Salomon <dilinger@voxel.net>]

There has been some talk on IRC about what kernel to release sarge with;
some people would prefer 2.6.8 (which hasn't been released yet).  If we
want to do that, I would suggest getting a jump on stuff now by preparing
2.6.8rc2 in svn, naming the package kernel-source-2.6.8 2.6.7+2.6.8rc2,
tagging and uploading to experimental (with associated arch-specific
packages uploaded as well).  This way, by the time upstream releases 2.6.8,
the packages will (hopefully) have made it through NEW; so,
we can do uploads of 2.6.8 and have it enter sid immediately.  The less
time we have to sit around waiting for things like this, the better.
