Hello, first of all(and for once) reddit is right, kali is design for pentesting and not as main os, if you want a hard install to practice, you should do a dual boot. so i really think you should install debian as main os, and maybe add kali on dual boot or in vm or live.
and if you have issue that prevent you to execute the task you want in kali then fix it, if it don't prevent you to pentest then you could just forget about it ;-)
