arp_ignore settings might be a case. As far as I do understand it, Linux
will answer on every interface to arp requests of every other interface
it has while arp_ignore changes this.
Thus not setting this option early enough opens a tiny timeframe in
which arp requests might be generated that are not wanted.
Such settings might be rare, but they are obviously not too rare for
this options to be in the kernel.
Also usually in most cases a short window where such bad responses could
be generated would not make that much a difference, but if it belongs to
the beginning of an connection that could cause a connection refused
that could cause some things to give up.
Or it might cause a dhcp server to think an address is already in use
and suddenly give some host another IP than usual and things like that.
All such situations are rare, as having multiple nets with the same IP
addresses or over-zealos arp watchers in them is not very common. But
this is only one of many options and mean that something else might have
some effects, too.
I do not think it will effect more than 1% of people and even those
it effects might not have significant problems, but is has effects and
those are hard to predict and when then happen they might very hard to
track down because of being a race condition.
