Hi,

I tried to configure podman to use crun-wasm and failed.

There seems to be 11 references in the org https://github.com/search?q=org%3Acontainers%20crun-wasm&type=code .

So the safer option would be to package crun-wasm IMO.

Asked for more information in the issue https://github.com/containers/crun/issues/1468 .

I would add the symlink. Other programs might look for the binary.
Looking at the references to crun-wasm I think having a crun-wasm package that:
- depends on crun and wasmedge
- creates a symlink to crun

does not sond so bad.
On the other hand, maintaining an extra package does not sound that nice either.


Regards,
Eugen

I believe the issue is that podman looks for crun-wasm binary by default.
I failed to configure podman to use crun instead of crun-wasm.
I created a simbolic link named crun-wasm:

sudo ln -s /usr/bin/crun /usr/local/bin/crun-wasm

Ouch! You're right. This worked when I enabled WasmEdge in crun, but
was changed upstream at some point since.

Apparently Fedora/RedHat ship a "crun-wasm" package, which contains a) this
symlink, b) a dependency on WasmEdge.

In Debian, the main "crun" package has a Suggests on libwasmedge0.

I see three paths forward:
1) We do the same, creating a new (almost) empty package.
2) We ship a /usr/bin/crun-wasm symlink in the crun package.
3) We patch podman to use /usr/bin/crun instead of, or in addition to,
/usr/bin/crun-wasm.

I don't particularly love option (1). I'm split between options (2) and
(3), not loving either.

Thoughts?
