     As of Ubuntu Server 22.04 or later, drives are presented correctly once more under `/dev/disk/by-id`. For a long time Ubuntu Server was not recommended (see [FAQ - Why not Ubuntu Server?](../01-overview/faq.md#why-ubuntu-desktop-instead-of-ubuntu-server)) however if you're running Ubuntu, the Server variant is now the recommended choice for a simple PMS deployment. In reality, [Proxmox](../02-tech-stack/proxmox.md) is our preference these days.
 
 There are a few options you have with regards to boot drive. The simplest option is buy a dedicated SSD for this purpose. Use this drive for the OS and temporary files (like in-progress file transfers) before moving them to your array. You might find putting your Plex metadata on an SSD such as this will help performance of library loading.
 
 Running the Gnome desktop on a server is a bit unnecessary as we'll manage this server 99% of the time via SSH. If you'd like to remove the desktop altogether, [here](https://askubuntu.com/questions/1233025/how-to-remove-gnome-shell-from-ubuntu-20-04-lts-to-install-other-desktop-environ) are some instructions on doing so from AskUbuntu.

 The filesystem wars have raged for decades and there is no right or wrong one to pick. However, we recommended either `ext4` or `xfs` to keep things simple. `xfs` allegedly works slightly better with large files (like media files) but there is not much in it.

     Due to some quirkiness in how Ubuntu server and desktop present drives under `/dev/disk/by-id` we recommend using the Ubuntu desktop variant. You can [disable the desktop services](https://linuxconfig.org/how-to-disable-enable-gui-on-boot-in-ubuntu-20-04-focal-fossa-linux-desktop) if system resources are at a premium.

 There isn't much call for NFS these days for home use and we've found most users can get by with only samba quite happily. If you need NFS, you'll know it.
