So, today, I wanted to try setting up a wireguard VPN server on my little raspberry pi at home. I... expected /some/ issues, but what I found dumbfounded me.

1 - I already had the wireguard package from the unstable branch of the main raspbian repo installed... Huh, okay.
2 - Setting up config was extremely easy... Wow, so the rumors were true. Wireguard really is almost dumb-simple.
3 - Failed to create a network interface? Oh, trouble, here it is! So lets see... modprobe wireguard... Nope. Don't have the module? What?
4 - Reconfigure package to rebuild the module - missing kernel headers? Huh... weird

This was the simple stuff... Then I went down the rabbit hole of the Raspberry Pi ecosystem:

1 - There is the Raspberry Pi Bootloader, that is apparently separate from the Kernel itself. And I didn't seem to have any of the standard linux-image-* installed... What? Weird, yet there I was, running a 4.19.42-v7+ kernel...
2 - No kernel and no headers... What... The... Fuck
3 - Okay, so... Lets just... try to install the latest kernel image then? One apt-get install... It downloaded the image, but during package configuration, it failed because... I didn't have... its headers? What? What for? And if it needs them (for whatever reason), why isn't the headers package as a dependency? Ugh, whatever...
4 - Another apt-get install and... Okay, building the initrd image aaaaand...
FAIL
WHAT. What is it this time!?

Oh... Ran... No more space on device? What? Is /boot independent? Of course it is, it has to be, its a bloody different filesystem

Okay, so, lets che-OH MY GOD WTF.

Its just bloody 45 MBs big! The entire /boot is just 45 MBs large. WHY. THE. FUCK.

This was a default raspbian install from I have no idea when. But... Why. Oh WHY would ANYONE pre-configure /boot to be this incredibly tiny!?

No wonder the new init ramdisk couldn't fit in there! Its already used up from 64%!

Thanks, Raspbian Devs, now I gotta reinstall the whole system because, yes, the /boot is, of course, sector 8192. Just far enough from 2048 that there are *some* sectors free - About 3 MBs.

So what did I try? Remove the partition and recreate it from the very beginning. Only... I never tried in in the past, and okay, kernel doesn't like having the partition where its image resides deleted on the fly, it will not give up FDs pointing there or something.

So now, I have a system I cannot reboot, or it will never boot back up :|

Thanks, Raspbian!

I need to get a cheap 1U somewhere or something T.T
