That's just avahi trying to work with an interface it thinks still

what does the output of cat /proc/net/vlan/config show?
It seems that the old settings are persisted somewhere and I suspect
either avahi or systemd.
I don't know if it is particularly systemd that's persisting VLAn
ids. VLAN interfaces are meant to persist until you issue a vconfig rem
command, but I don't know if systemd persists the interfaces across
reboots.
As far as I know, it shouldn't. VLANs require an explicit .netdev
service file.
cat /proc/net/vlan/config gives no such file
Given that the issue seems to be centered on dhcpd and it not knowing
which subet relates to which vlan interface why with nothing in
/etc/network/interfaces does syslog show this when trying to start dhcpd:

With no vlans defined in /etc/network/interfaces and no ip addresses
assigned to the plain eth0 or eth1 how come its still referring to
eth1.1 and eth1.2 even after a reboot?
