Today I added a temporary subnet on an interface for temporary
testing.
When I restarted dhcpd, it went into maintenance state due to this
error (setsockopt: IP_PKTINFO: Bad file number). The complaint about
the unknown subnet seems benign but the setsockopt error is not. This
issue seems harmful for servers which may have a lot of interfaces,
which may come and go:

for igb1 (192.168.0.1).
