Initially this experiment was about booting kernel directly into VM with qemu
and making minimal initramfs

At 29.11.2025 I decided to copy few binaries to initramfs to see if I can get
a working shell. Turned out it's actually easy and adding bin/dash, 2 libs it
dynamically links to at runtime (ld and libc) and making correct symlinks was
enough to get me started

binaries copied:
/bin/dash
/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2
/lib/x86_64-linux-gnu/libc.so.6

links:
/init -> /bin/dash
/lib64/ld-linux-x86-64.so.2 -> /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2
