Oh bummer...

I wonder why git-clone -b doesn't accept a sha1sum.  Oh well.


So how do you folks handle pinning a revision of, for example, the
kernel?  I naively assumed that I would specify
BR2_LINUX_KERNEL_CUSTOM_REPO_URL and
BR2_LINUX_KERNEL_CUSTOM_REPO_VERSION, which appears to do what I want,
but it seems wasteful to have to clone the whole Linux repo just to
get that one clone.

I suppose I could tell menuconfig that the (Atmel) kernel I am cloning
is available on github somehow and have the magic "fetch a sha1sum
from github" work.  I'll go think about that for a bit.
