or you can build your own live cd:

# BUILDDIR=/home/my_live_cd
# mkdir $BUILDDIR

# cd /usr/src
# make buildworld
# make buildkernel
# make installworld  DESTDIR=$BUILDDIR
# make distribution  DESTDIR=$BUILDDIR
# make installkernel DESTDIR=$BUILDDIR

echo '/dev/acd0 / cd9660 ro 0 0' >> $BUILDDIR/etc/fstab
echo 'init_script="/etc/"' >> $BUILDDIR/boot/loader.conf
echo "exec /bin/sh" > $BUILDDIR/etc/
# you probably should script /etc/ and
# mount rw memory fs over /var, /tmp, and others

# add useful packages
mount -t devfs devfs $BUILDDIR/dev
for pkg in apg-2.3.0b_1 bonnie++-1.93.04 stress-1.0.0; do
    cp /home/pkgs/${pkg}.tbz $BUILDDIR/
    chroot $BUILDDIR pkg_add /${pkg}.tbz
    rm $BUILDDIR/${pkg}.tbz
umount $BUILDDIR/dev

# generate ssh keys
chroot $BUILDDIR /etc/rc.d/sshd keygen

# mkisofs -quiet -b boot/cdboot -no-emul-boot -r -iso-level 4 -V "my
live cd" -o /home/my_live_cd.iso $BUILDDIR
# burncd -v -s max data /home/my_live_cd.iso fixate

You can even read some new manpages while fixing servers :)

    Everything should be made as simple as possible, but not simpler.
