installation check

[Sam Steingold]

I have some reasons to believe that my installation is corrupt
(random crashes &c).
Is there a way to check it - short of wiping everything out and re-installing?
what I have in mind is taking every package and checking that the
checksum of each file in the package and on disk is identical.
thanks.
