Re: Desired behaviour of "ifconfig -alias"

But you called it "confusing". That's just your personal

If asked what -alias does, would you really reply "it removes the
primary IP,
while leaving the alias?" Be honest here.

Also note that it doesn't hurt anybody.

If you run RELENG_6_2, and a jail fails to start, this command is called.
And instead of unaliasing the jail's alias, it (because of a bug in the
shipped
rc.d scripts), it removes the primary IP.

So that is a real life, non-third-party incident, where a machine was
knocked
off-line unexpectedly, because of this behavior. Sure, it didn't *hurt*
me,
but knocking a machine off-line is a pretty serious side effect,
especially when
it isn't documented.

Errors in the other direction are more likely to result in a machine
remaining
reachable.

Fortunately, it appears that a fairly strong consensus is appearing in
support
of an eventual refinement of this behavior.
