mkosi-initrd: add 89-ethernet.network for network profile

[bluca]

networkd ships with no configuration enabled, so we need to symlink one in for it to do anything

[yuwata]

Why not to enable default network config option?

[bluca]

Sorry what do you mean by that precisely?

[yuwata]

I mean, why not to enable -Ddefault-network=true meson option? Or, do I misunderstand the point of this PR?

[DaanDeMeyer]

@yuwata That would have to be done in Fedora, where we obviously cannot make that change for backwards compat concerns

[yuwata]

Ahh, I forgot configs in mkosi repository does not build systemd but use systemd provided by distribution. Sorry for the noise.

I don't think bookworm is a target for this, but the file changed its name in commit 9b7a624267fddc5c20bd15480e7a393d7a3b270e from 80- to 89-, so there might be the unlikely case where this produces a dangling symlink (pre 255).

[bluca]

pretty sure most things here won't work with 255, so a danglign symlink is the least problem

[behrmann]

Looking at the CI failure, there is a certain problem: The thing coming in is a traversable, since the thing in resources need not be backed by a filesystem, the package could be whatever weird thing. I'm not sure that e.g. Python wheels support symlinks (they're zipfiles that have to work on windows). While that might not be relevant when running mkosi from source, this will break zipapps or possibly distro packages where building a wheel might be an intermediate step.

A workaround might actually be to ship the mkosi.extra as a tar file, which can be adressed as a single file as a resouce.

Python used to be fun, you could assign a banana to a bathtub and it would just do it

[behrmann]

Well, you can still do that, but now we just get warned before trying to take a bath in the banana. :)

[behrmann]

In the context of the initrd profile the simpler workaround might even be to duplicate the file contents here, at the same time sidestepping the renaming issue mentioned above.

[DaanDeMeyer]

That means we don't get updates, I prefer the symlink
