Hello list, The main system on this box is ~amd64 plasma, but I also have a small rescue system which is amd64, no desktop. I use bootctl from systemd-boot to manage the UEFI images.
My question is: how much of the bootctl-installed image is essential for booting? In other words, if I install the ~amd64 kernel (5.1.9), what effect will that have on booting the rescue system; and if I install the amd64 kernel (4.19.44), what effect will it have on booting the plasma system? In practice, I install the ~amd64 kernel and hope it doesn't affect the rescue system too much; and it seems not to. Could I do better? -- Regards, Peter.
