Things look quiet here. But I've been doing a lot of blogging at dan.langille.org because I prefer WordPress now. Not all my posts there are FreeBSD related. I am in the midst of migrating The FreeBSD Diary over to WordPress (and you can read about that here). Once the migration is completed, I'll move the FreeBSD posts into the new FreeBSD Diary website.

I couldn't mount the floppy
I was trying to mount my floppy but it wasn't working:
# mount /dev/fd0 /mnt
mount: Operation not permitted

Say what?  I tried again:

# mount /dev/fd0 /mnt
mount: Operation not permitted

OK.  Does my mount point exist?

# mkdir /mnt
mkdir: /mnt: File exists

Yes.  That's there.  So what's wrong?

# tail /var/log/messages

Ahhhh!  There's the problem!  A dirty file system.

Running fsck
Here's how I ran fsck:
# fsck -y /dev/fd0
** /dev/rfd0
** Last Mounted on /mnt
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups
10 files, 2428 used, 387 free (11 frags, 47 blocks, 
                                  0.4% fragmentation)

***** FILE SYSTEM MARKED CLEAN *****
# mount /dev/fd0 /mnt
# cd /mnt
# ls
boot              boot.config     kernel.config   kernel.gz

OK.  There's my files!  Now back to the 3.2 install.
