Because I don't use any LVM, RAID or encrypted devices, I can safely turn off all nearly all

`fedora-\*storage\*` services. To turn off these services, we use the `systemctl mask` command.
|
||||
A bonus with that mechanism is, that no rpm %post script turns them on automatically.

```console

$ cd /lib/systemd/system

I also like the idea of automounting (systemd's automount feature was an idea of mine :-).
|
||||
So I turn /boot in a "mount on demand" mountpoint. Also having /tmp as a tmpfs is one way to reduce
|
||||
disk activity (useful for e.g. a slow flash disk). My resulting /etc/fstab looks like this:

Because NetworkManager is started also by the graphical login target,

I can remove it from the multi-user target and it will be started in parallel to the gdm login screen.
