I'll be on a metered internet connection while I'm on the road and I'm
wondering if there's a way to keep on top of the latest versions of
these without doing a full download every time I want to sync:
Is there an rsync command that would work?
I you go to https://github.com/beagleboard/kernel/tree/beaglebone-3.6 you will see in the box next to "Git Read-Only" the URL below.
git clone https://github.com/beagleboard/kernel.git
That will create a kernel directory from which you can make a working copy if you like.
From the kernel directory, "git pull" will update with whatever changes subsequently are available.
e.g If it is at 3.6-rc6 and the latest is 3.6-rc7, "git pull" will update 3.6-rc6 to 3.7-rc7 and if a few days later some patches are added to 3.6-rc7, "git pull" will add them.
