Annoying thing with #flatpak apps is that their temporary files go to `$XDG_RUNTIME_DIR`, which is a ramdisk created by systemd. Ramdisk created with very limited size, causing for example #Signal to fill it, or things to quite comically fail when #calibre tries to transfer a larger book to your device. And I haven't yet found a way to adjust the size of this ramdisk, and only an ugly hack to work around this. #Linux#sysadmin
@solene thank you. I'll try that later, though flatpak has some assumptions and isolations. It probably has a better chance of working for calibre than IMs, and for that someone suggested also other variables to try, specific to calibre
