Most probably so. But at that point, I was pressed for time. Had the
system need only /dev/{console,null} then all will be well. If not?
Then another cycle of LiveCD-mount-mknod-restart.
Much faster to just `genkernel initramfs` while waiting for the snafus
to be fixed

There are cases for each, but I personally prefer going single-user.

[gentoo-user] Anyone running a gentoo guest on virtualbox?
