>Organization:
Univ. Bonn, Germany
>Environment:
FreeBSD wigner.th.physik.uni-bonn.de 4.3-RELEASE FreeBSD 4.3-RELEASE #1: Thu May 24 18:01:27 CEST 2001     conrad@merlin.th.physik.uni-bonn.de:/freebsd/misc/src/sys/compile/MERLIN  i386
>Description:
In some cases, for instance if your /etc/fstab is corrupted, the 4.3R
kernel mounts / as wd0a for IDE drives. However, there is no device
to remount root to rw (/dev/wd0a does not work, /dev/wd0s1a is not present)

This is only a small thing, but since nowadays the boot device on IDE
depends on the hardware (ad0 or ad4), this might be a problem for many people

>How-To-Repeat:
delete fstab, reboot :-)
>Fix:
Either include /dev/wd0s1a by default
or make the kernel mount using the ad driver if fstab is present
