My summary of the above three postings
* This is very annoying
* not a bug but expected behaviour, use "IgnoreIfMissing on;"
* can observe a likewise behaviour, in the meantime using the recommended fix
What manual page says, note twice "default"
IgnoreIfMissing on|off
A flag indicating whether or not the interface is ignored if it
does not exist at start-up. By default, radvd exits.
This is useful for dynamic interfaces which are not active when
radvd starts or which are dynamically disabled and re-enabled
during the time radvd runs.
Current versions of radvd automatically try to re-enable interfaces.
Enabling IgnoreIfMissing also quenches certain warnings in log
messages relating to missing interfaces.
Default: on
Where I read the two defaults being in conflict, is it more important
to read
Current versions of radvd automatically try to re-enable interfaces.
So this bug _might_ be fixed. \o/
Leaving it on open for several reasons.
* Having a reference for
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=642808
which was open at the time of writing this triage update
* maybe adding IgnoreIfMissing in the examples
* the ambigues defaults in the manaul page
