Correct. wireguard drivers were considered "unstable" at the time we
cut the v3.7 release so they are only available via edge/testing repo
which means you need to run the kernel from edge/main repo.

The simplest thing to do would be to make a traditional disk install,
and upgrade this to edge (in theory you can run setup-alpine, and
select "none" for disk, edit /etc/apk/repository and change all 'v3.7'
to 'edge', and then run `setup-disk`, and then select the disk you want
install it to.

If your run-from-ram boot media is writable (disk of some sort), then
you should be able to edit /etc/apk/repository (change to 'edge') and
then run update-kernel to recreate the boot/ directory of your boot
media, with the latest kernel. You also need to include the
wireguard-vanilla driver in the boot/modloop-vanilla loopback file. I=20

`uname -a` will tell you the running kernel version. `apk search
wireguard-vanilla` will tell you the version of the kernel driver.
