i agree with your backup argument.

actually, backup thingies can prove worthful in other scenarios too.
but restores are only necessary when something or somehow messed 
something up. in the perfect world backups are taken but a restore is 
never necessary.

anyhow, i am not sure what could be done better. if a rpm builder forgets 
to define a file correct than it will be overwritten, of course. i am 
sitting in front of a OS-X right now. if apple does an update, files are 
overwritten *poof* . but rpm provides the infrastructre to do it right. 
thats a good thing, but its not foolproof of course.

so, backup. please.
