/mnt/wsl/wsldata/home/developer /home/developer none bind 0 0

### Expected Behavior

No error for mounted data drive

### Actual Behavior

Dec 16 08:28:46 PBD-IT-WL-rOMw1 mount:
Dec 16 08:28:46 PBD-IT-WL-rOMw1 /mnt/wsl/wsldata: mount point does not exist.
Dec 16 08:28:46 PBD-IT-WL-rOMw1 unknown:
Dec 16 08:28:46 PBD-IT-WL-rOMw1 mount:
Dec 16 08:28:46 PBD-IT-WL-rOMw1 /home/developer: special device /mnt/wsl/wsldata/home/developer does not exist.
Dec 16 08:28:46 PBD-IT-WL-rOMw1 unknown:
Dec 16 08:28:46 PBD-IT-WL-rOMw1 unknown: WSL (2 - init-systemd(redhat)) ERROR: UtilCreateProcessAndWait:707: /bin/mount>
Dec 16 08:28:46 PBD-IT-WL-rOMw1 unknown: WSL (2 - init-systemd(redhat)) ERROR: ConfigMountFsTab:2172: Processing /etc/f>

plus the well know message on login:

wsl: Processing /etc/fstab with mount -a failed.

and eventually I have that drive and use it!

This is the same with 6.x. Some version doesn't print it, but journalctl has it for any WSL above 2.4

### Diagnostic Logs

_No response_

Start by reproducing the reported `wsl --mount` command with the shown `/etc/fstab` entries for `/mnt/wsl/wsldata` and the bind mount. Review the `mount -a` output and `journalctl` messages, then compare behavior across the mentioned WSL versions. Done means the mounted VHD and bind mount process without the reported fstab errors.
