Even robust systems have hiccups. Here is how to fix frequent NXD Diskless Free errors: root=/dev/nfs nfsroot=192

export ROOTDIR=/export/diskless/freebsd-14.2
mkdir -p $ROOTDIR
cd $ROOTDIR
# Install base system into $ROOTDIR (e.g., using makefs or tar from a release)
tar -xvf FreeBSD-14.2-RELEASE-base.txz -C $ROOTDIR
