I have been using the same version of this script on at least 4
different machines and _never_ had a problem while updating. Actually,
that's not true. I did have one issue with mailman (hence why I am not
upgrading it) because I use Exim as an MTA and the mailman port does not
detect it and uses the defaults for Sendmail.... But once in 2 years in
not too bad I think.

Hence the line that saves the database and sanitize it.

They are attached.

I do save the database in case things go very bad but I never had to use
it. Still, better safe than sorry.

Pardon? Decoding the script does not take any time... It upgrades your
ports tree to the latest cvs (cvsup line) tree of the ports. It then
checks the database for consistency using pkgdb -F. It then backs up
the database using tar and date. It then calls porteupgrade to re-built
all the pacakages and their dependencies. Then, it prints what has been
upgraded or problem ports to the screen. =20
If that is still too complicated, read the manual for cvsup, pkgdb, tar
and portupgrade.

You are aware that there were a couple of security fixes in the last few
days that you should install...

Whatever works for you. Of course, note that your system maybe unsecure
and unsafe because you do not upgrade packages for such a long time. =20
