So you broke your HomeLab again...
We've all been there, gotten a bit too comfortable with an SD card that's working and forgotten about it until it inevitably hits its write limit. Sure I can pull the data and copy it to a new card but where is the fun in that?
Let's do something more interesting, let's make a USB stick boot drive for a Pi 4 8GB that mounts a MergerFS array of HDDs... Why you ask? Because hardware is expensive and this is what's leftover in my lab.
This is a bad idea... but it's what's hosting this blog.
