+    <teythoon> I've got this idea about the pid 1 issue you mentioned
+    <teythoon> can't we just make init pid 1?
+    <teythoon> I mean the mapping is rather arbitrary, we could make our init
+      pid 2 or something and start sysvs init as pid 1
+    <pinotree> not totally sure it is that arbitrary up to the first 4-5 pids
+    <teythoon> y is that?
+    <pinotree> at least i see in hurd's code that /hurd/init is assumed as
+      pid=1
+    <teythoon> hurds init that has to stick around for the fs translator sync?
+    <pinotree> hurd's init does the basic server startup
+    <pinotree> iirc it also takes care of shutdown/reboot
+    <teythoon> that's what I meant
+    <teythoon> and if it wouldn't have to stick around for the translator sync
+      it could just exec sysvinit
+    <teythoon> I just think it's easier to patch hurd than to remove the
+      assumption that init is pid 1 from sysvinit
