with new rhel 7 it's not difficult to image common setups
where... which one is it - multi-user.target or
network.target is the target and no gui
these naturally most often than not will be
multicore/multisocket systems
and an admin would like to set a sort of hard ceiling above
which users running their heavy-numbers-crunching apps could
not go
with old libcgroup it was fairly straightforward, with
systemd quite opposite, but I might be wrong, only started
looking at it all
but if I'm right I would be strange redhat missed/dropped
all these scenarios where users can be controlled/limited by
cpusets
any other way to restrict users in/via cgroup cpu? I'm still
thinking systemd

Just a curiosity question: If you segregate a user to just one CPU
core, does that really save a system from being crippled if they max out
that core, or crash it? I'd have thought that the rest of the system
would still be affected to some degree. At the least, it'd have to be
completely isolated from the user's core. And it strikes that me that a
user using the operating system isn't isolated, they interact with it.
