I took the time to compile a list of commands to get a debian based system to stake eqt from the ground up.
I built the list while testing on a minimal fresh debian stretch netinst system. But I only did this until the compilation. All commands after I copied together from other running systems of mime.
There are probably a lot of errors in there and understanding might be difficult, but if you know the basics of linux and half-know what you are doing, this list of commands should get you going for a staking system.
