                             Revisions of versions
                                        
I spent today making sure I was using the lateset version of the greylist
daemon [1] across two production servers (one running Postfix [2]; the other
Sendmail [3]) and the development server (or rather, servers as I actively
develop on two different machines). 

Good thing too, because there was one file that was completely different on
each machine, and quite a few files that were the same on two or three and
different on the remaining machines. 

You might ask why I'm not using some form of revision control, but I am. Only
I don't think it's right for how I work. I could use CVS [4], since it comes
already installed on Linux distributions, and I'm currently using it [5] for
mod_blog. But it does have a few problems [6]. Then there's subversion [7],
but the last time I checked, it was a bear to install, and I'm not sure how
one actually goes about creating a new project with it. 

No, for this project, I decided to try git [8]. Dead simple to install. Dead
simple to create a new repository. Dead simple to create and checkout
different branches. Incredibly fast too. But managing a central repository
with git seems to have eluded me. Perhaps it's because I don't fully
understand how git is used properly, or perhaps it's because I want a
centalized development model, not a decentralized one (even though I do
development across different machines). And the pulling or pushing of changes
from one repository to another doesn't seem to work as I would expect it to
work. 

It's a pity, because other than “checking in” and “checking out” revisions,
it's a nice, fast program.
