## What are the changes about?
updated instructions in readme.md for runit to properly disable `agetty-tty2` and unlink services
## What existing issue(s) does this resolve?
on void linux, when `runit-void` package is upgraded it re-adds the symlinks for agetty, including `agetty-tty2`, if its not properly disabled (`down` file in svdir)
https://github.com/void-linux/void-packages/blob/master/srcpkgs/runit-void/INSTALL
so everytime that package is updated, both `agetty-tty2` and `ly` start making `ly` unusable until you manually unlink it
