If you use Firefox, it added pdf editing in since 106. I like it compared to xournal. https://www.mozilla.org/en-US/firefox/106.0/releasenotes
Devuan then!
Fedora for me as it seems to work the best for my hardware, will be moving to Kinoite when I get the chance. i already am using distrobox and Flatpak in general. Tried NixOS (with Root on ZFS) but couldn't get hp-wmi module to work on on it. I was having some problems with Opensuse Nvidia drivers (wakeup from suspend didn't work sometimes). The one thing I miss on Fedora, that Opensuse has is Full-Disk Encryption.
