"initial RAM disk". When booting a kernel image, it's sometimes necessary to access additional features, almost always kernel modules and a utility to load them, which 1). aren't compiled into the kernel (say, a stock kernel), and 2). can't be read from the primary root filesystem because of a dependency deadlock with these features. The solution is to create a small filesystem image with just the tools necessary to get you through the boot sequence. This is loaded as a RAM disk, then saved to /initrd after boot, presumably so that you can examine its contents in the event of any problems. I've used an initrd in the distant past, when I was dual-booting GNU/Linux and NT. Actually, it was a triple boot, with the NT bootloader being the primary, DOS being a boot option from this, and LOADLIN.EXE being an option on an DOS boot menu. LOADLIN would bring up a kernel which didn't have SCSI support, so I created an initrd with the appropriate modules to bring up my GNU/Linux installation. Cool hat trick. Not often used these days. See lilo and kernel sources documentation for more information. -- Karsten M.
