HDD has 100x the storage capacity vs SSD. What are you talking about?
If you’re set on TrueNAS, then just build a box to do that.
If you want a low power solution, go with Synology or Qnap.
You don’t really need to worry them at all, because they won’t be actively affecting anything, but the process would be like this:
dnf autoremove
and see if that will remove these extra kernel packages. If not, use rpm -qa | grep kernel
to find all the surface kernel packages to remove.But again, and let me stress this because it sounds like you’re not super experienced with this: there is no benefit to removing these packages versus just switching the running kernel, only risk.
You’re getting that error because it’s a meta package-a package that represents a collection of packages-so you need to actually remove the set of packages it installed and replace it with another kernel. Simply installing an alternate kernel package should configure it to be the default booting kernel on Fedora. You want a replacement kernel to be installed before manually removing whichever is active right now.
Don’t know about PDF viewers, but check the software store. I know there are a lot.
