swapd

Swapd is a noteworthy swap creation deamon that boasts of dynamic monitoring capabilities of the system's memory, allowing it to detect when swap creation is required. This software's intelligence is evident in the fact that the swap size is automatically determined with respect to sysadmin limits.

Installation is a breeze, provided you follow the outlined steps, and you are logged in as root. Firstly, running 'make install' will suffice. Secondly, glance over /usr/local/etc/swapd.conf to ensure that it aligns with your preferences. You will also need to create the swap directory chosen in swapd.conf, which will only be accessible by the root.

To complete the installation process, add the following line to /etc/rc.d/rc.local: /usr/local/sbin/swapd. If you recently recompiled the kernel, it is recommended that you reboot your system now. However, if you haven't, 'rehash,' and running swapd as root will do the trick.

All in all, swapd is a powerful tool that should undoubtedly have a place in your software collection. Its intelligent dynamic monitoring, ease-of-use, and simple installation process make it a must-have.
