SYNOPSIS
systemctl set-property UNIT PROPERTY=VALUE...
DESCRIPTION
systemctl set-property modifies unit properties at runtime. By default, changes are persistent and stored in drop-in files under `/etc/systemd/system/<unit>.d/`.
Common properties include CPUQuota, MemoryMax, IOWeight, and other resource control settings.
PARAMETERS
--runtime
Make changes temporary (cleared on reboot)
COMMON PROPERTIES
CPUQuota= - CPU time limit (e.g., 50%)
MemoryMax= - Memory limit
IOWeight= - I/O priority
TasksMax= - Maximum tasks
CAVEATS
Some properties cannot be changed at runtime. Persistent changes are stored as drop-in files. Use `systemctl revert` to remove custom properties.
HISTORY
The set-property subcommand enables runtime resource control adjustments, supporting dynamic system tuning without service restarts.
