Yes.

Yes. See systemd.exec(5):
"This controls the memory.limit_in_bytes and memory.soft_limit_in_bytes
control group attribut

Memory limit and memory soft limit aren't rlimits, but cgroup limits?
Is this documented somewhere?
Sorry if I spread any misinfo.

AFAICS that is simply not correct. The resource limit logic and the
cgroup memory logic are orthogonal.

Yes, getrlimit.
yes, rlimit_as

Do you mean getrlimit? man 2 ulimit on F16 says it's not implemented.
If it's getrlimit, is it RLIMIT_AS?

you cannot detect when you've hit the soft limit other than by getting a NULL
on malloc.

Hello all
We want to limit the memory a service can use using MemoryLimit= and
MemorySoftLimit= described in systemd.exec.
As I understand it, LimitAS= and LimitRSS= aren't particularly useful.
Linux doesn't even implement LimitRSS?
