10 months ago Building a minimalist Linux Kernel as per Floppinux manual at least spit out some error messages...

10 months ago I recorded the whole boot process in VirtualBox 7.0 setting the max CPU utilization to 1% [ which should translate to 46 MHz on my overclocked i7-6700K @ 4,6GHz]:
I guess I did feck up the .config for said Linux Kernel re: xz compression and initramfs settings... Should be quick to fix...

10 months ago Progress is being made with the latest commit and whilst the current image version does not yet fully boot, it's now hanging at the init process...
Two Options to fix it:
/etc/init.d/rc/etc/initThis should - in theory - run the minimalist toybox executeable and it's build-in bash-style shell just fine.

10 months ago Personally I prefer to use #2 as "Configuration by Exception" will prevent me from getting a Tom Scott "Future Me" issue down the line...

10 months ago Issue still persisting as of current version of the image...
Will need to find out why it still dislikes the /etc/init file...

10 months ago Thx to @sweetaibelle for hinting that I overlooked at the persisting issue of the failing decompression...

10 months ago Apparently @sweetaibelle found a fix for my botched rootfs.cpio.xz and I found the culprit in the init file:
#! /bin/toybox it should've been #!/bin/toybox sh in line 1.Otherwise toybox otherwise just vomits out it's main message to tell which commands are implemented.

10 months ago @sweetaibelle in theory this commit should fix it to the point the very bare-bones OS/1337 prerelease will boot through cleanly.
I've to update & rebuild the rootfs.cpio.xz to include those fixes but that should've done that issue...

10 months ago The boot issue have been solved.
Autocompletes and so forth are still broken but it does boot and at least can cat welcome.txt and from here on out this should get much smoother...
@sweetaibelle your hint fixed it.

I've gotten some cals for help out and some replies were quite helpful, including a different .config for the Kernel...
This needs further examination and triage
