We are forcing a change through the installer, which is where
the majority starts from.  We don't want to enforce a change
twice.

We can't really see if we installed or went through a factory
reset, so this is (was) the best of both worlds in conjunction
with the new installer feature.

While here, annotate that it is possible to leave it "empty".

This reverts commit 5eb2c986.

This is a shell script to make recovery as recoverable as
possible, now with a clear license and the ability to apply
inline or reboot for a clean configuration cycle.

error: setsockopt(..., SO_RCVBUF, ...) failed: No buffer space available

In the longrun all macro entries should go, but for now a replace should be sufficient.

ipsec, cleanup non-functional nat before ipsec logic and ui for 17.7. In case the feature will reemerge at some point, it would be better to move it to the firewall section anyway. for reference about this long standing issue see https://github.com/opnsense/core/issues/440

This reverts commit c4628a0b.
It looks like pkg can't handle php70 to php71 at all.
