Ah, yes, good points. I wasn’t thinking of reproducible buids or the binary
packages. I was hoping to make it a little easier for a user to install a
basic working buildslave*. After the install, our user must run the
‘buildslave create …’ command (with parameters we can’t determine ahead of
time) to initialize the the files that the plist will be pointed to. All that
is beyond the scope of the portfile so I guess just providing a template of the
plist is a reasonable approach.

*Our buildbot port is currently non-functional as we have a newer version of
sqlalchemy-migrate than it can use. Being looked at upstream:
