- added "skip" and "seek" to dd.
* swapoff -a was not working. Now it is.
* init did not cleanly unmount filesystems on reboot. Now it does.
* "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
Now both work.
* Some architectures (PowerPc) assume chars are unsigned, so they could
not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
