ramlog acts as a system daemon that maintains log
files in memory instead of hard disk while the
system is running. On startup, it creates a
ramdisk, copies files from /var/log into the
ramdisk, and mounts the ramdisk as /var/log. All
logs after that will be updated on the ramdisk.
When shutting down or restarting the service, it
saves log files back to hard disk. This service
drastically reduces the frequency of hard disk
usage, which can be useful when the system runs on
battery or uses flash memory instead of a hard
disk.
