that's nice.

that's not.  that sort of "assumes" that component-b is needed *ONLY*
for component-a.  so...hey!  if i pkg_delete xv, should i expect it to
pkg_delete libjpeg for me?  same sort of thing.  likewise libc.  xv
has an unstated dependency on lbc...and i don't want it removing that.
so if i shut down nfs which requires networking, i don't want
networking shutdown for me.  but i also don't want nfs started up if i
have no networking started.

# rl -compenent-greywolf
* rl: component-greywolf requires: component-netbsd
** rl: <shutting down component-netbsd>
* rl: <shutdown component-greywolf>

it's a bad idea.  once you get into "incredibly finely tuned modular"
systems like that, everyone comes up with their own "legitimate" uses
for it that don't quite match (a) they way it comes out of the box or
(b) the way other people use it.

and then there's the dependency thing.  those scripts, if they're
gonna work the way they purport to work, they really need to be
idempotent.  and they never are.
