It's "worse" than that; rebasing is designed for a _private_ development 
model. git-rebase is a very handy tool for people like myself (people 
without a downstream that is) and it basically enables the quilt model 
of a stack of patches on top of git but public trees that have people 
pulling from them should generally not rebase or everyone who _is_ 
pulling finds a different tree each time.

Linus is vehement about this also. There have a few threads about it and 
the most recent was:

http://lkml.org/lkml/2008/5/17/190

I'm also not an experienced git user (not other than in my own leafnode 
developer mode, certainly) but I expect Linus might not terribly mind 
answering a few questions about the model -- ALSA is a significant 
subsystem and it switching to GIT might even make for a nice "this is 
how you do that as a subsystem" treatise...

(ie, also added linux-kernel)
