[wplug] initrd directory

[Poyner, Brandon]

The man page for initrd (4) on a redhat system explains it pretty well.  Of course steps 1 through 6 help explain what 7 is all about.
 
         7. If the normal root file has directory /initrd, device /dev/ram0 is
         moved  from  /  to  /initrd.  Otherwise if directory /initrd does not
         exist device /dev/ram0 is unmounted.  (When moved from / to  /initrd,
         /dev/ram0 is not unmounted and therefore processes can remain running
         from /dev/ram0.  If directory /initrd does not exist  on  the  normal
         root file-system and any processes remain running from /dev/ram0 when
         /linuxrc exits, the behavior of the kernel is UNSPECIFIED.   See  the
         NOTES section for the current kernel behavior.)

	I was working on a small server that had ClarkConnect loaded. It seemed
	to be RedHat based and I was trying to clean up a bunch of stuff that
	the previos admin had left behind plus establish a mirror drive.
	
	Long story short their was a directory /initrd off of root that was
	empty and so I thought it was not needed. I had a SuSE box to compair
	against and so I deleted it. ....Several hours later (thinking it was
	hardware or other unrealted issues) I recreated the directory and it
	booted. Once that was done I could then get back onto the internet and
	did some googling. Found that it realy should be thier on RH systems.
	Why? Why does their need to be an empty directory their for the initrd
	to load and work? My SuSE box and RH based firewall don't even have
	initird files as they are completely monolithic for all the major
	drivers (mass storage drivers).
	
	In need of edumakashon.
	
	Thanks,
