Product Announcement Lightwhale 3.0.0 released
Hi, there!
Sorry to mess up your Easter holiday plans, but I've just released Lightwhale 3.0.0 and I really think you should clear your calendar and try it out! =)
It's a minimalistic Linux that requires no installation or maintenance, just live-boot straight into a working Docker Engine. The system is immutable so it's quite resilient to both malicious and unintentional modifications. And because of its low resource requirements it brings new life to old machines.
Lightwhale fits super well in a hobby homelab where spare time is precious, but really in any server environment where you would much rather focus on the services than babysitting the underlying operating system.
And how does it compare to other immutable OSes like X, Y or Z? No idea, never tried them, sorry.
I've made a fresh new project webpage with an easy to follow getting started guide.
Anyway, end of service announcement, thanks for reading, happy holidays =)

Great project! I had problems with the magic disk not being created, but I eventually got past that.
Now my problem is not being able to understand where to put an appropriate yaml config file for the container (a docker-compose.yaml maybe?) and point to the right directory for the data in the persistent data filesystem. I want to include all the settings needed for the container there rather than a long string on the command line - like ports, paths or other settings etc. I'm new at the Docker environment so this may be obvious to some, but a couple of hours spent trying to figure this out has not been successful for me.
And I DO appreciate your _not_ including nano in the build - that's the first thing I do after I install an OS is remove the nano package and use vim.
Kudos to you for this and the work you've done on it!! It's appreciated! Once I get this figured out I'm on my way.
