So in my numerous attempts to load the 7.300 beta on my device via the up2date package, I've come to realize that a large update via the web browser just isn't feasible. It always seems to time out the browser, even if I extend the auto-logout to 63,000 seconds ... it may not auto-logout now, but it still times out something during the process of the upload. Usually after it's been twenty minutes and 85% complete.
I propose a directory on the router that I can drop the .gpg file into on the router (via scp, of course) and the device will periodically check the directory for new additions, popping it up there as a viable update when it does.
