Some sd partitions are set up as a side effect of the bootstrap
process. Look at mbrpart() in /sys/src/boot/pc/part.c, which
is called for each sd while probing for possible boot devices.
The comment says
/*
* Fetch the first dos and all plan9 partitions out of the MBR partition table.
* We return -1 if we did not find a plan9 partition.
*/
That's why termrc does further probing, to find any extra
partitions besides the above. To do the same for a CPU server,
you would have to add something to the local cpurc.
