I run it occasionally, no need for a cron job.

I have cronjobs that run once a week or once a month.

This "defrags" them and keeps software management running quickly as
new.

This last part I think is odd. I see no reason for this.

After a few months of installing a lot of software and updating them
makes the databases slow down.

After running that script it's like a brand new installation.
Which it the is, as for package management.

There seems to be a point, at least here.

I understand the rpm bit. I do not get the 'defrag' bit by renaming
files.

It's not the renaming that does it.
It's the making new copies of the files.

Renaming is an intermediate step required for copying the files to a new
location with the same names.

Then reading the new copies of the files is faster than the old ones.

I guess that how significant this speed increase is, depends on a lot of
factors. But as I'm always on old slow HW everything counts.

Perhaps somebody else can explain what happens. I asume that is
still on ReiserFS or is that already on EXT3 (or fat16?)

The partition in question is ext3.
As an explanation I'm offering that it gathers the pieces of the files
in a new spot on the disk in one place.
