Description=Resource-capped slice for user monitoring / status-bar scripts
Documentation=https://www.freedesktop.org/software/systemd/man/systemd.slice.html

[Slice]
# Cap the entire slice at 50% of one CPU and 512 MiB of RAM. If i3blocks or
# any other status-bar tooling enters a fork-storm regime (as was observed
# when polling scripts forked awk/tr/grep/bc every tick), the kernel will
# throttle the slice rather than let it eat the box.
CPUQuota=50%
# MemorySwapMax=0 is required on systems with zram: without it, a cgroup
# hitting MemoryMax thrashes zram instead of being OOM-killed, freezing
# the machine. See .github/skills/oom-prevention/SKILL.md.
MemoryMax=512M
MemorySwapMax=0
TasksMax=256

# Make sure killing the slice reaps every descendant.
