systune 0.5.13+nmu1 (armhf binary) in ubuntu lunar

 This program writes kernel parameters, previously saved in a configuration
 file, to the /proc filesystem. This enables kernel performance to be
 adjusted without recompiling the kernel.
 .
 systune can be alternative to sysctl(8). It is also started after the most
 daemons and other init.d scripts, so it can be used as "second stage" sysctl.
