why this is overhead for you???

i found netbsd upgrades easier than anything else i know including many
linux distribution.

just because netbsd is a COMPLETE system, so fetching new sources,
recompiling and installing is enough, and i'm sure all will work.
don't know how with -current things, but they are not "production"
releases so they may be problems
