The runit-init program, normally installed as /sbin/init sends signals
to pid 1 when told to reboot or halt the system.  The runit program
doesn't provide any other communication channel than signals (combined
with magic files), so it relies on being the process with id 1.  If you
change that, nothing else should break but this IPC, but you then have
the problem to find out the id of the runit process on shutdown.  Tools
like pidof are exactly what runit replaces with a reliable solution.

I can't see how this relates to your change, building the package should
never make the system hang, unless the system is buggy.
