>Description:
At boot, mountd practically always fails to resolve hostnames in
netgroups used in /etc/exports.  This never used to fail, but has
started doing so recently (perhaps since 2.99.10).

The errors logged are:

Jan  9 04:43:01 hrothgar mountd[606]: "/net/hrothgar/proj-8     -maproot", line 1: can't get address info for host nix.gw.com
Jan  9 04:43:01 hrothgar mountd[606]: "/net/hrothgar/src-1      -maproot", line 2: can't get address info for host nix.gw.com
Jan  9 04:43:01 hrothgar mountd[606]: "/net/hrothgar/src-2      -maproot", line 3: can't get address info for host nix.gw.com

The /etc/exports file contents:

/net/hrothgar/proj-8    -maproot=root           dist-us
/net/hrothgar/src-1     -maproot=root           dist-us
/net/hrothgar/src-2     -maproot=root           dist-us
/home                   -alldirs                 -network 204.80.150.0/25

Running "env - sh /etc/rc.d/mountd reload" as soon as I can login
after booting results in the exports file resolving correctly.

DNS is needed to resolve the hostnames, and this has not changed.
The DNS server is up and running.

The netgroups are from a local db (not from NIS).  The first host
returned from that group is nix.gw.com:

hrothgar:~> netgroup dist-us
nix.gw.com
morgoth.gw.com
hrothgar.gw.com
grendel.gw.com
dit.gw.com
beowulf.gw.com
stinky.astron.com

>How-To-Repeat:
Reboot and observe.
