Hi, first i downloaded the snap- infected version from ubuntu.mate.org with torrent.
Then i did unsquashfs the filesystem.squashfs.
After chrroting inside it i did
sudo apt autoremove --purge snapd
sudo rm -rf /var/cache/snapd/
then i did add tghe firefox -prefences.d no snap file and added the mint no snapd apt patched file.
After that i did apt-get update , closed the sqaushfs an did regenerate the filesystem.size file.
Last but npt least used isomaster to add the modded file. The iso size shrunk dramatically abou 1 GB.
after applying some themes:
Note that cups and pulseaudio need still to be recompiled to prevent snap from entering the system.
Its blazingly fast and runs well even with themes from ubutnu 22.04.
