There's a 

http://xenbits.xensource.com/gitweb/?p=people/dstodden/blktap-dkms.git;a=summary

But that's not really what most people would be looking for -- it's
rather generating dkms-tars/debs from a cloned bunch of
blktap/next-x.x.x tree out of

http://xenbits.xensource.com/gitweb/?p=people/dstodden/linux.git;a=summary

Which are then meant to automatically compile against mainline. They
will auto-patch themselves to match anything between 2.6.32 and 3.x.

Actually I didn't see any announcement that we're exporting packages at
this point, but the directory name looks about right. If s/o (presumably
Jon et al) can get me a login, then I wouldn't mind dropping prebuilt
packages in some subdir in there, regularly.

We're mainly targeting Ubuntu[/Debian] with that stuff, but DKMS is not
a deb-only system. Could generate RPMs too, anywhere where dkms is
supported.

It's not very distro-happy output, which is what Jon's stuff would
eventually produce, but will do the job.

Cheers,
Daniel

PS: The DKMS stuff is mainly to make distribution painless. For folks
building/patching their kernels manually anyway, consider just to remote
my linux.git and just merge a matching blktap/next tree.
