Managing local changes I don't want to push?

[Martin Sjögren]

Hello list, new mercurial user here.

I've recently started to use mercurial (long time user of cvs and
subversion, casual user of darcs) and I'm wondering if mercurial can
solve a problem of mine.

We use it in a more or less centralized style, having an "official
repository" that everybody pull from and push to, but people set up
other repositories too. Now, what I want to do is have some local
changes (e.g. an extra target in a Makefile) that I want to be applied
whenever the "official" Makefile changes, but I don't want these changes
to tag along when I push my changes back to the official repo.

I tried out MQ, but either I don't understand how to make it work for
me, or it can't do what I want to do... Am I right in that since
changesets depend linearly on each other, once I commit a changeset for
my local Makefile changes, all my further commits in that repository
will depend on it, so if I want to push another changeset, I can't do
that without including the Makefile change?

Is there another way to do it, or am I doomed to keep it as uncomitted
local changes the way I would in cvs/svn?


Thanks,
Martin
