I have a slightly crazy system setup with an SSD drive bind-mounted to the application/lib/data directories in /usr, as well as /opt. Given the upcoming udev news, I decided to get a dracut initramfs working for the bind mounts. I got the bind mounts working by using an /etc/fstab.sys file like this: /dev/sdb1 /ssd ext4 noatime,nodiratime,discard 0 2 /sysroot/ssd/opt /opt none bind /sysroot/ssd/usr/bin /usr/bin none bind etc. etc. However, before every bind mount dracut spews the following error: [: 1: Illegal number: device node not found This appears to be caused by the _fs= line in /usr/lib/dracut/modules.d/95fstab-sys/mount-sys.sh: fstab_mount() { local _dev _mp _fs _opts _dump _pass _rest test -e "$1" || return 1 info "Mounting from $1" while read _dev _mp _fs _opts _dump _pass _rest; do [ -z "${_dev%%#*}" ] && continue # Skip comment lines if [ "$_pass" -gt 0 ] && ! strstr "$_opts" _netdev; then fsck_single "$_dev" "$_fs" fi _fs=$(det_fs "$_dev" "$_fs") <-- this causes problems info "Mounting $_dev" if [ -d "$NEWROOT/$_mp" ]; then mount -v -t $_fs -o $_opts $_dev "$NEWROOT/$_mp" 2>&1 | vinfo else mkdir -p "$_mp" mount -v -t $_fs -o $_opts $_dev $_mp 2>&1 | vinfo fi done < $1 return 0 } The $(det_fs ...) function -- which is located in /usr/lib/dracut/modules.d/99fs-lib/fs-lib.sh -- calls udevadm with --name=$_dev. In the case of a bind mount, $_dev is actually the olddir argument and not a device, hence the error. The boot proceeds normally, so nothing appears to break. It appears that the current version of dracut just doesn't expect bind mounts.

Bob, is this issue still present?
I no longer see the Illegal number messages in dmesg.
