I did NOT see such problems. Actually, I never made /etc/networks working to
set netmask  for class B subnets. I tried to use /etc/networks to set mask
from 2.1.x to 2.2-x, I got no lucky at all. So, I have to use netmask flag
explicitely in ifconfig command and -mask in /etc/exports file to do so.

That the only problem I encounted for mountd is it must start at boot time.
e.g., if there was no /etc/exports exist at boot time, then, add it after
boot up, and try to start mountd at this time, entire file system will hang.
