Im giving a go fedora silverblue on a new laptop but Im unable to boot (and since im a linux noob the first thing i tried was installing it fresh again but that didnt resolve it).
its a single drive partitioned to ext4 and encrypted with luks (its basically the default config from the fedora installation)
any ideas for things to try?
You might be right. I was thinking of it in terms of a traditional distro, as I use vanilla Debian where my advice would apply and yours probably wouldn’t.
From what I do know, though, I guess /etc would be part of the writable roots overlaid onto the immutable image, so it would make sense if the immutable image was sort of the initramfs and was read when root was mounted or something. Your command is probably the correct one for immutable systems.
