it's probably a good idea to explicitly run
`update-alternatives` in the install_java script
so that the result is clear.

as a rule, custom things go into /usr/local/bin
not /usr/bin.
a number of things (I'm mostly thinking about
tomcat here, but..) already start with wrapper
scripts, so it's not a big deal to continue on with
that.

do we have a list of projects which will not work
with the openjdk packages available? how big is
the problem?

not using the ubuntu packaged version of that (or
anything..) requires extraordinary justification.
(e.g. so `update-alternatives` etc still works...)

for 5.5 can we just continue with the sun packages
and put off worrying about openjdk for 6 months?
