Yes, I was using a very recent version of the pasky tools, I had created the repo this morning with git init YOUR_RSYC_URL_FOR_LINUX-2.6. I did time git pull origin and watched the fur fly. Then, the flurry of patching file blah messages, followed by a rather pregnant pause after the last patching message. I wasn't complaining about the 4 minutes, just the lack of feedback during the majority of that time. And most of it was after the last patching file message. > > Anyway, it looks like you are using pasky's scripts, and the old > "patch-based" upgrade at that.

I'm on dialup from home, and I suspect not very many folks want to hear the sad tale of how long it takes to get the kernel over 56k dialup.
