I find it easier/nicer to do the 'mergemaster -p' step before
rebooting into single-user mode...  That's at least partially
because I'm trying to keep accounts in-sync across multiple
machines.  On the other hand, I don't see any advantage in
waiting to do that step after the reboot.

To me, it seemed like a good idea to put all these steps (and a
few others) in a source-file under /root.  That way I only have to
type in one thing -- and I'm much less tempted to try short-cuts
if there is only one thing to type in.

What is that 'cd src' doing in there?  What causes you to be
in /usr at that step?  I'm pretty sure that I'm in / or /root.
