Yeah, that's one of the reasons I really like arch -- it's like the good
old (and rather nice) cp-al/patch method except that arch keeps track of
most of the annoying details for you!

I also really want this!
tla doesn't use hardlinks for source trees now, for obvious reasons --
you can't rely on every tool the user uses to change his source tree to
snap hardlinks before modifying files.
However, I think there should be a (user) option to use hardlinks
instead of copying for all tree-copying in tla; it of course should
default to `off', and by setting it to `on' the user is saying he
promises to use only safe tools, and is prepared to deal with the
consequences of not doing so.
`safe tools' includes at least emacs and patch, which I use for
99% of all modifications -- and anyway, like you, I use `cp -al' trees
for the kernel already, with no problems whatsoever.
