what should I do before dist-upgrade to unstable

["Alvaro" <alvaro.arenas@gmail.com>]

Hi list.

I have been using debian/testing for a year long. I would like to have
the leatest software (eg. latest kde). Therefore, I want to update to
unstable. I read somewhere that unstable is as stable as any other
distributions (latest suse)

I know I have to do:
edit source.list

aptitude upgrade
aptitude dist-upgrade

But I read somewhere that I should execute some other command,
something to do with the critic packages

Some help?


Greatings
