Part of the reason for "-n" was for when fsck'ing the root filesystem
when they were mounted read/write on boot. Using my favorite old legacy
Unix O/S (Ultrix) as an example, if you fsck the boot disk and it
changes something, you get the following messages:
***** FILE SYSTEM WAS MODIFIED *****
***** HALT PROCESSOR WITHOUT SYNCING DISK *****
Does anyone know if NetBSD ever mounted it's boot disk read/write right
from the word go, instead of needing the "mount -u" bit?
