wireguard kernel modules

[bjo]

Usual Arch Linux provides a wireguard kernel module for the linux and the linux-lts package.

Using Archlinux ARM we have to use wireguard-dkms which leads to a module rebuild every time a new kernel comes out.

I think Arch ARM devs prefer dkms to avoid adding extra packages to the repos. DKMS isn't my favorite but if you want, you can make your own PKGBUILD for wireguard and manually build as needed:

I do this on my armv7h:
$this->bbcode_second_pass_code('', 'pkgbase=wireguard
