You don't need a bootloader if you don't reboot
That's why it's called FOSB: Free and Open Source Bloat... Grand Unified Bloatloader, U-Bloat...
on a serious note, is possible to never reboot?
like an high availability server that can't never go down, how do they manage kernel updates? *
Kernel live patching, which basically rewires kernel functions at runtime, lets you update the kernel without rebooting. I don't remember how old that is though.
there's also kexec
That's still downtime, it just doesn't reboot firmware
You can go without rebooting if you always have power, don't care about updates (security) and don't run into bugs.
It's done with multiple servers I guess. One updates/reboots while the other ones don't.
