It seems like we're bound to start building up a longer and longer list
of these sorts of things that will need to be done on restart, doesn't
it? Any ideas for what to do once there are three or four tasks that
need to be done?

I looked for a good while for some code that we already have that does
this, but it turns out there isn't any. Barring that, pjones suggests
copying this code:
http://git.kernel.org/?p=utils/util-linux-ng/kzak/libmount.git;a=blob;f=sys-utils/switch_root.c;h=c43225da2e14dbc671251a037caef022b5b35c40;hb=HEAD#l41
It's already in use, and it already handles some corner cases. I just
wish it were in a library.
