Two years or so tried fedora Silverblue and one the main issue i run into was storage. I had 180 GB SSD at the time and it filled to 90-something in a week. Now i have a 240 GB SSD and thing of try an immutable distro but worried about the storage space.
Anyone got insight into how big an SSD do i need?


The OS shouldn’t take that much storage regardless of whether its immutable. If you’re talking about containerized software, then it will depend on what programs you plan to run.
do you mean Flathub or something like docker/distrobox. I remember using toolbox for some CLI commands.
