Re: Problem installing gentoo linux/genkernel environ on alpha platform

Hi,


From the output below, it appears that aboot is working fine given that
the kernel has loaded.  This looks like a problem with your ramdisk image
to me.  I agree, check your fstab, but on the ramdisk image.

The device file with major:minor number 01:00 is /dev/ram0 or /dev/rd/0
depending on whether you are using devfs.
