While this PR is not merged, one can install host-spawn binary to directory $HOME/.var/app/com.visualstudio.code/data/node_modules/bin (it’s already in VSCode Flatpak’s PATH)

[lbssousa]

Wouldn't it be better to package this as an add-on for VSCode Flatpak (e.g. com.visualstudio.code.tool.host-spawn)?

Could it be possible to ship separate add-ons for providing host-spawn symlinks to notorious binaries (e.g. com.visualstudio.code.tool.host-spawn.podman, com.visualstudio.code.tool.host-spawn.fish, com.visualstudio.code.tool.host-spawn.bash, etc.)?

i made a pr.

This looks good and works better than the current flatpak-spawn snippet. Not entirely excited to depend on something else than flatpak-spawn but host-spawn seems okayish in general.

cc @bilelmoussaoui This would be good to merge given #315

Big thank you to @alatiera, @bilelmoussaoui, and everyone else that participated in getting this merged!

Please update host-spawn to version 1.4.2. It's needed to spawn host-system podman properly.

Wanna file a PR? Bumping the version and changing the sha should be everything needed hopefully :)
