Exposing zfs snapshot to windows previous version using samba vfs_shadow_copy2

This was much trickier than I had originally anticipated and have spent a few hours testing.

The config from samba wiki absolutely works, but it wasn't ranked higher in search engine and it's not general enough. https://github.com/zfsonlinux/zfs-auto-snapshot/wiki/Samba

Tested on ubuntu 22.04LTS, samba 4.15.9 and windows 11.

# Usage: notarize-macos.py <Apple ID username> <Apple ID password> <file>
#
# Note: The --primary-bundle-id flag is hard-coded below, so you'll want to
#       change that!

Running Unifi Controller in systemd-nspawn with cloud-init

This uses Ubuntu's server cloud image as a stateless container to run the UBNT Unifi Controller software. Configuration data is stored in a directory outside the container. Cloud-init is used to automatically set up the container image, so a new version can be dropped in with minimal effort. This should work with pretty much any modern Linux distro with systemd.

Setup

Systemd-nspawn prefers to store its machines on btrfs, so if your /var/lib/machines is not currently btrfs, you should create one and mount it there. Otherwise it will automatically create an image file at /var/lib/machines.raw and mount it.

Setup armv7h chroot under x86_64 host (Archlinux/Archlinuxarm biased)

Simple way to setup an arm chroot for building packages for your arm devices. This is an alternative to cross-compiling where you are limited to only linking against the libs in your toolchain.

Setup chroot-fs

You can store the chroot wherever you like. I choose to store it in a disk-image which I mount to my filesystem.
