Yeah, I thin we're definitely in territory that is not covered by the
boot scripts as written here.
This thread has got me thinking though, how useful would something
like 'foo_enable=conditional' be? What I'm thinking is that you could
define a script in foo_condition that rc.d would run. We could either
do a straight yes/no, where if the script exits successfully (exit
code 0) then we run the service, and if it fails (non-zero exit code)
we don't. OR, we could have the script return the argument we want to
feed that service's startup script.
I think that may have some utility here, what do y'all think?
