There is this notion of "kexec boot"; I've never tried it, but it's
documentation claims "kexec  is  a system call that enables you to
load and boot into another kernel from the currently running kernel."

Maybe it comes with too many ifs and buts to be a viable approach.

..I used to "kexec reboot" a lot in my pre-systemd Debian days,
AFAIR, bought me nice long uptimes with new kernels. ;o)

    What's the purpose of kexec ? I see one main: using a Linux session as the bootloader, a bootloader more heavily customizable than Grub. Additionally it saves a few seconds. Are there any other ?
