Right. I'm sorry I wasn't more clear in my initial e-mail, I wasn't
advocating doing away with config files, or even talking about hdparm
specifically anymore.  (Keep in mind I was trying to explain the
concept of config files, and commenting-out lines in particular)

What I tried (and failed) to say was that I would prefer if user
front-end applications more often included a user-friendly way to
update the config-file, thus guaranteeing syntax-correctness of the
config-file and making the overal experience more user-friendly and
transparent to the user. For tools/daemons that don't have a GUI at
all I would indeed not call the absense of a graphical tool 'lazy'.

As for hdparm, it would be best if users didn't have to fiddle with it
at all. By all means leave the option for people to tweak to their
hearts delight for those who want/need to do so, but some of the more
basic settings should be controlled (or at least managed) by the
(applications included in the) OS. Such as whether to use DMA or

Question: Does Ubuntu's current inability to configure dma in hdparm
(either automatically or in a configuration panel somewhere) make it
slower than it could be? (Not a smug or rhetorical statment this, I'm
actually asking.)  If the answer is 'no' then I vow to never fiddle in
hdparm again. :-)
