EDIT: I was building .#dev_image instad of .#packages.x86_64-linux.dev_image which resulted in an image with 100 layers. The latter results in 32 layers 👍

• Need to add an old-style init script for docker (see /etc/init.d/docker in the regular image) -- we do not need to have systemd actually running looks like
• Need to set permissions on /var/run/docker.sock
• Need to install ca-certificates

I added a script in init.d to start the docker daemon with the proper group set up in the background.

• Need to install ca-certificates

Ca-certificates do get installed, the explicit SSL_CERT_FILE is most likely not getting preserved when running sudo.
We could either change the init script to run a sudo -E service docker start or explicitly add the env variable to the docker start script in the init.d folder. I decided to do the latter.

TIL that busybox has its own slightly different version of getopt 🙃

Yep, I removed busybox entirely and pulled in ncurses for clear and su for su.

When running make build the gnu getopt version now gets pulled it from the PATH.

make build now working for me.

I'll go ahead and merge this PR.

I will need to make a follow-up PR, as we have some tests depending on hard-coded OS values (mostly clistat package relying on Elastic's library, which in turn expects OS information in /etc), and some pty tests failing because they are unable to find env and grep binaries in the $PATH.
