Happened several times to me.

I never bothered to complain, thinking I messed someting up.
Since it's so easy to start from scratch,
i.e. delete all packages and replace anew,
corrupt pkg database hasn't really been a big
issue for me. I do think, however, that there
must be other reasons for corruption, except
an interruption at just the wrong time.

BTW, what's the use of /var/cache/pkg?
It's grown to > 2GB. Can I safely delete
all packages from there?

Thanks

Anton
