Oh, You Needed More Information?

Looks like I keep having to revisit how I'm running my WSL2 instances. Previously, I had needed to create an ext4-formatted VHD to host PVCs within (first) KinD and (then) Minikube clusters. At the time that I wrote my (KinD) articles, I only had a single WSL2 instance (running Oracle Enterprise Linux 9). As such, the wsl-level mount command that I was using seemed to be sufficient. However, as my needs evolved, I needed to be able to run more than one WSL2 instance. I noticed that, even though my mount command was succeeding, the mount point was no longer showing up inside any of my instances. Digging around, it seems like, because my VHD-hosted ext4 filesystem was created on the bare disk, WSL stopped being able figure out where I wanted it mounted inside my (preferred) WSL2 instance. Turns out, the fix was to give the mount command a bit more information. Instead of the (now insufficient):

wsl --mount --name openclaw-data --vhd G:\OpenClaw\openclaw-data.vhdx

I need to update the command to

wsl --mount --name openclaw-data --vhd G:\OpenClaw\openclaw-data.vhdx --type ext4

Adding that `--type ext4` seems to have (for now, at least) given WSL2 enough additional information about my intentions that, when I log into my (preferred) WSL2 instance, it now shows up where expected:

$ df -Pht ext4
Filesystem      Size  Used Avail Use% Mounted on
/dev/sdd        251G   32G  207G  14% /
/dev/sde        118G   65G   49G  58% /mnt/wsl/openclaw-data

Honestly, I don't know why the first one ever worked: "dumb-luck", presumably. Hopefully, I won't have to continue tweaking these kinds of settings as my WSL2-related needs continue to evolve
