Rancher Desktop is what I've switched to in place of Docker Desktop.  It has some differences that
need to be worked around (see previous gist for setting the network subnet a container uses).

One other issue is that after about 24 hours, the docker socket just stops listening.  It is currently
on Rancher's radar, but in the meantime, the only real solution is to stop and start the entire
Rancher Desktop app.  The below script does exactly that.

A second issue is that a running k3s cluster consumes enough CPU/power that it raises the temperature
of the Mac when it's idle and significantly cuts down on battery life.  The second script will stop
the k3s subsystem and kill all running containers, bringing the CPU usage down to a very low level.

Merging git repositories, putting one of them into a subdirectory

For this you need git-filter-repo installed (filter-branch is discouraged).

On systems with UEFI Secure Boot enabled, recent Linux kernels will only load signed modules, so it's about time DKMS grew the capability to sign modules it's building.

These scripts are extended and scriptified variants of https://computerlinguist.org/make-dkms-sign-kernel-modules-for-secure-boot-on-ubuntu-1604.html and https://askubuntu.com/questions/760671/could-not-load-vboxdrv-after-upgrade-to-ubuntu-16-04-and-i-want-to-keep-secur/768310#768310 and add some error checking, a passphrase around your signing key, and support for compressed modules.

dkms-sign-module is a wrapper for the more generic sign-modules which can also be used outside of DKMS.

Installation

1. Create a directory under /root, say /root/module-signing, put the three scripts below in there and make them executable: chmod u+x one-time-setup sign-modules dkms-sign-module
