I'm running the 2.6 xen kernel on CentOS 5.3. My goal is to use larger-than-normal ramdisks. I can see that the rd module is statically compiled into this kernel, so I tried passing the option ramdisk_size=262144 during boot, but dmesg shows that it gets reset to 16384K. I can also see that this is the size stipulated in the kernel config.
Do I have to rebuild the kernel to make this work? If that's the case, can I rebuild it with the new size and still use an initrd? If the answer is no, how do I go about making sure that the drivers I need are compiled into the kernel? I know the most basic steps to building a kernel, but I'm not entirely confident I know what I'm doing here. I've looked for howto's but haven't found anything covering this case yet. Any help is appreciated.

tmpfs will do that for you: http://en.wikipedia.org/wiki/TMPFS

Not a bad idea at all, but there is still the possibility of getting swapped out with tmpfs. I really want to make a big ram disk.
