If you are using a GPS device with nmeaattach(8), please switch to ldattach(8) now.
The nmeaattach command has been removed in -current, so has the
nmeaattach_flags option in /etc/rc.conf (replaced with ldattach_flags).
Please note that ldattach(8) has a slightly different synopsis than
nmeaattach(8) had:
nmeaattach cuaU0
becomes
ldattach nmea cuaU0
