{∅, {∅}, {∅, {∅}}} : Rage Against the Meat Grinder

While this Adelie Linux has ISO images available, from their main page, the links to "Software" are dead.   Does this mean their "apk" package manager (Alpine's apk?) will have dead repositories?

What is real?  The only way to know for sure is to proceed with a small installation on a partition.  I do not want to use "Virtual Operating Systems."

I have a couple small partitions made for Kiss Linux which are free, and I want to test out a /home partition's software.  I want to see if Sage 8.8, compiled in Funtoo will run with Kiss/Alpine/Adelie/Void/Artix/Slackware, even with a minimalist installation.

All I would require is something like screen (a terminal multiplexor) so alt-tab-whatever through terminals [sage, isympy, ~/bin, nano sessions].  And yet, some kind of minimal desktop may be necessary to run things like Visual Studio Code, Atom, a web-browser ... although there is text-based links for web-browsing, and emacs for writing code.

When I truly lose all my marbles I might grow a set of balls and build Linux from scratch; but, I am an honest man, and therefore a humble man.  I lack the confidence.

and yet, with Adelie, while preparing the installation medium, the USB flashdrive, there is not the usual option for GPT partitioning.  Just MBR with BIOS (or UEFI-CSM). I would have to wing it and simply not install the bootloader, or I could do it manually ...

(Adelie Linux Documentation)

It uses an intuitive graphical interface for the installation, even KDE Partition Manager.  I just had to ignore the BIOS-centric layout and the weirdness of using the MBR-style format on the USB drive.  I do not want to trust this installer to  install and boot loader.  I will handel that manually with rEFInd and efibootmgr afterwards.  I may have to hit the F-12 key while turning on the computer to choose (after reboot if it sneaks the bootloader in somehow).

PS:  Ibra, I was researching that Plan9 UNIX distro. That was novel.  And Haiku - a completely unique operating system.  There is no solid ground for us to stand on ... all murky.  Those who may have noble intentions when they begin a project may end up sad, bitter, or otherwise, as disappointed and dissatisfied as the Buddha himself.
