That's exactly what I did, more or less. All seems fine.

Yea, maybe. I read the man page on emptytree. I get it actually replaces
by a "reinstall".   Does this do more than if I just reboot after

emerge @system @world and then reboot?  

I'd be curious to know exactly what reinstall does that is not covered
by just starting up a given code again? 

Is it that it forces a reinstall and stop/starts the binary without
rebooting?   

Rebooting catches *everything* even better than --emptytree ?
