So you are proposing to run all kind of daemons as root to avoid them
being hit by the OOM killer early?
Resilience also means to have each process run with the minimum
priviledges it needs. Running daemons as root when they need not
certainly does not increase resilience.
The proposal of a syscall to prevent a process from being hit by the OOM
killer early is certainly a better idea. Especially since you can use
POSIX capabilities to safeguard the call.
But the easiest and best solution for the OOM problem is still to add the
needed resources. And that ain't going to change no matter how sophisticated
the OOM killer gets in selecting the order to kill processes.
