I booted up in to the kernel, did # ls /dev/sd*, and the only things displayed were /dev/sda and /dev/sda1. That is the place where my USB stick gets mounted. > The default in new kernels is to only use /dev/sd*. I'm totally confused. Doesn't "sd*" mean "SCSI disk drive"? When I was installing Gentoo from the CD, I had to mount my main hard drive as /dev/sdb5. When I built my own kernel, it needed /dev/hdh5. This seems crazy. Is it documented anywhere in Gentoo? -- Alan Mackenzie (Nuremberg, Germany).
