Does the current Fedora Live CD support loading the rootfs to RAM? I thought I remembered that as a boot option in some of the earlier releases (Fedora 6?).
I googled a bit and found reference to a 'live_ram' command line arg and tried adding that and booting, but I get the following error:
Done copying live image to RAM. eject: did not find a device /dev/root in /sys/block/
Then I get a "Good Luck" message and a rescue prompt.
My test PC is a Core2Duo w/ 2GB of RAM, SATA HD, and IDE CD/DVD drive.

The code is still there. It's not exercised much, though. We removed it from the menus as it can be pretty confusing to do reliably (how much RAM is "enough")

Yep, that's the trick

Sounds like a bug in eject -- it should follow the link and then do the eject

Yeah, eject is apparently looking in /block/sys to check for the 'removable_media' flag for the specified device... and it's assuming the device name isn't a symlink.
