Want to split apart fish config into 3 directories:

fish-functions

and config-fish

I was thinking of having a 3rd for abbrs but that's too many >_<

debian nested virtualization

I'm trying to get nested virtualization on debian working, so I can test my "ronin" command. But I don't really need nested virtualization; the test command can run from a host, and clean up its environment etc, such that if it works, that means it should work for a new machine... no need to be perfect here. Anyways here's a virtual machine where I try to install libvirt and stuff and it fails

vagrant@bookworm:~/hack$ history
    1  ls
    2  up
    3  sudo apt update
    4  apt list --upgradable
    5  sudo apt upgrade
    6  ls
    7  sudo apt install libvirt
    8  sudo apt install libvirt0
    9  ls
   10  sudo apt install vagrant
   11  mkdir hack
   12  cd hack/
   13  ls
   14  vagrant init debian/bookworn64
   15  vi Vagrantfile
   16  vagrant up
   17  cat
   18  sudo apt install qemu-system-common
   19  sudo apt install qemu-system
   20  cd hack/
   21  ls
   22  vagrant up
   23  sudo apt install qemu qemu-kvm libvirt-clients libvirt-daemon-system virtinst bridge-utils~
   24  sudo apt install qemu qemu-kvm libvirt-clients libvirt-daemon-system virtinst bridge-utils
   25  sudo apt install qemu-kvm libvirt-clients libvirt-daemon-system virtinst bridge-utils
   26  sudo systemctl enable libvirtd
   27  vagrant up
   28  whoami
   29  sudo usermod -a -G libvirt vagrant
   30  vagrant up
   31  virsh net-list
   32  virsh net-dump vagrant-libvirt
   33  ip addr
   34  vagrant up
   35  vi Vagrantfile
   36  sudo virsh net-list
   37  sudo ip link delete virbr0
   38  sudo ip link delete eth0
   39  vi Vagrantfile
   40  vagrant up
   41  vagrant up --debug
   42  egrep --color -i "svm|vmx" /proc/cpuinfo
   43  sudo virt-host-validate
   44  vu
   45  vagrant up
   46  sudo virsh
   47  history

And here's the error:

Haven't fixed it yet, ah well, like I said I don't really need nested virtualization to write some tests for this. Virtualization isn't the solution to everything... though it is cool ...
