Disable Swap on Raspberry Pi OS Trixie

The old method of disabling swap no longer works.

This will still work on previous versions

sudo dphys-swapfile swapoff
sudo dphys-swapfile uninstall
sudo update-rc.d dphys-swapfile remove
sudo apt purge dphys-swapfile --yes
sudo apt autoremove --yes

As the new version uses zram

Edit the swap configuration file

sudo nano /etc/rpi/swap.conf

Then find the lines in the config as follows remove # and set size ot 0

One is under Files the other is under zram

[File]
FixedSizeMiB=0
[Zram]
FixedSizeMiB=0

Reboot your system.

Viewing in htop we can see Swp has 0/0K size
