Not sure if this has been requested in the past but would there be any use in having a base-lts group package?
At the moment you have to load base then install linux-lts [remove linux package]
Or bootstrap pacman then load packages required.
Does not seem much point in loading both kernels, as you have fallback option.
Apart from the burden to maintain base-lts is there a benefit in removing the linux package?
For myself I find it very convenient to have 2 kernels installed - I may do some "experiments" with one kernel knowing I can always rely on the other one.
Also upgrading the 'linux' package is less stressful with a "backup" kernel (the falback image of the upgraded kernel may not always be the answer when the problem is in the kernel itself).
