After some more testing it seems that ceph just does no pickup on some of
ceph.conf changes after bootstrapped. It was possible to bind to the v1 port
using `ceph mon set-addrs aio1 [v2:172.16.6.210:3300,v1:172.16.6.210:6789]`
It was defo not an issue with OS syscalls or permissions, just ceph n
Just to add that a dump of that live config does indeed not show the v1 port.
So it seems to be ignoring the config. I tried the alternative mon host
syntaxes without success.
