What happened?

Logs attached appropriately.
The install script doesn't account for busybox-based distros, so it's completely broken on Alpine Linux.
When trying to run it, I get this...

❯ ./install.sh install
 -> Using script

 -> Current git mirror: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git

cut: unrecognized option: delimiter=/
BusyBox v1.37.0 (2025-12-16 14:19:28 UTC) multi-call binary.

Usage: cut [OPTIONS] [FILE]...

Print selected fields from FILEs to stdout

	-b LIST	Output only bytes from LIST
	-c LIST	Output only characters from LIST
	-d SEP	Field delimiter for input (default -f TAB, -F run of whitespace)
	-O SEP	Field delimeter for output (default = -d for -f, one space for -F)
	-D	Don't sort/collate sections or match -fF lines without delimeter
	-f LIST	Print only these fields (-d is single char)

How can one reproduce this on a non-busybox distro ? when I try this it fails even earlier

~/Documents/Gethings/linux-tkg $ busybox sh ./install.sh config
./install.sh: line 44: declare: not found

Also, can't just use bash and gnu utilities ?
