Aye, I'm on udev (new install, plus specifying "nodevfs udev" as kernel arguments), and while I'm not worried about disk space, I did like that Ubuntu and RHEL made it easy to see if a device was connected through a quick glance at /dev/, but while trying to truobleshoot a SATA drive (whole other issue there), /dev/ is reporting four serial devices, but only one of them is a block and the other three are... console devices? Bit of a pain.
I've skimmed the udev guide at lunch, but once I get off work I'm going to give it a thorough reading. If Gentoo hasn't taught me anything else, it's to read the bloody manual. Twice.
Thanks for the help though!
