>Description:
If you've installed base.tgz from (say) 10.0 but debug.tgz from 9.3, there's no easy way to tell that you've made this mistake short of carefully scrutinizing the content of the tarballs.

There's /etc/release in the base set, but nothing to check it against in the other sets.
>How-To-Repeat:
1. install 10.0_RC2 base, debug, &c.
2. update with sysinst to 10.0_RC3 base but forget about debug
3. try to debug a program that crashes in base
>Fix:
Yes, please!
