Not really, I pulled it together from a bunch of random posts lol

Maybe I should write one, but in essence you:

• Stop all non-OS essential services

• Create a filesystem in a chunk of RAM

• Pull essential OS files from the installed OS into it recreating needed directories (Though you could probably just use a tiny pre-built distro but meh)

• Pivot root into it

• Reload services (when they restart they'll be restarted in the context of where you pivot rooted, prior they're still running under the context of the installed OS)

• Unmount the boot drive

• Then do what ever you need to do

• ???

• Profit
