snapd needs squashfs support in kernel

[cerebrate]

WSL 2, build 18917.

While WSL2 doesn't have the issues with snapd described in #2374 , we now have another blocker. snap install now fails after downloading the snap, as it is unable to mount it, since the WSL 2 kernel doesn't contain squashfs support. (Per /proc/filesystems and the obvious test:

.)

Any chance we can get that included?

Still have one of the blockers.

In the meantime, pending an answer to that, bet you could, with a little hackery, probably get over the hump with this.

We've added squashfs support to the kernel, it will be available in an Insider build soon.

Second try is the trick....

@therealkenc I am still facing #2374 in WSL2. Is it just me or is it a known issue for wsl2 too? @cerebrate says he doesn't get it in WSL2.

[cerebrate]

@bbhopesh To clarify that, I don’t get in WSL 2 because I can run systemd in WSL 2. (Using my https://github.com/arkane-systems/genie code.) Without that or some equivalent method to get systemd up and running for snapd, I’d still get it, and snapd won’t run without both that and a recompiled kernel.

[therealkenc]

Yes, as of this writing snapd won't run "out of the box" on WSL2. CONFIG_SQUASHFS should roll out RSN though. There is usually a couple week delay from tag fixinbound to the change actually making its way into a Windows Update rollout.

[cerebrate]

Since this is in the kernel now, closing.

Here is a naughty procedure to use snapd with systemd. See this link https://forum.snapcraft.io/t/snapd-on-wsl2-insiders-only-for-now/13033

[cerebrate]

So much reinventing of the wheel. 🤷‍♂

[therealkenc]

My one-liner seems to have a legs. Yeah.

[cerebrate]

In so many very similar wrapped variants, heh. This is about the fifth one I've seen, counting mine, and I haven't been looking.
