But what Linuxisms does s6 have? We just had a bunch of fun trying to get it to build right, and the uptime stuff really threw us. It's fine though, I found that s6 may start growing an IPC mechanism so we could possibly do a launchd/jobd style service later (ie to run things upon event changes, like ifup, ifdown, ifcreate, ifdestroy, arbitrary messages, etc) so I may try incorporating it again. :) -adrian
