Introduction http://www.linux.com/archive/feature/141231

From http://freshmeat.net/projects/ramlog/
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.

Steps for manual installation of ramlog on Fedora: (Steps for other systems may vary)

1. add or update kernel paramter ramdisk_size=xxx where xxx is amount of memory for the ramdisk ramlog will use you should update it in your /etc/grub.conf or /etc/lilo.conf file

3. cp ramlog.8.gz /usr/share/man/man8/ramlog.8.gz
4. cp ramlog.cron /etc/cron.daily #or to other dir based on your need
5. /sbin/chkconfig --add ramlog
6. /sbin/chkconfig ramlog on

Last RPMLINT report:
RPMLINT report:
ramlog.noarch: W: incoherent-subsys /etc/init.d/ramlog $prog
The filename of your lock file in /var/lock/subsys/ is incoherent with your
actual init script name. For example, if your script name is httpd, you have
to use 'httpd' as the filename in your subsys directory. It is also possible
that rpmlint gets this wrong, especially if the init script contains
nontrivial shell variables and/or assignments. These cases usually manifest
themselves when rpmlint reports that the subsys name starts a with '$'; in
these cases a warning instead of an error is reported and you should check the
script manually.
