mkdir /proc; mount -t proc proc /proc (I think); check man mount_proc

to the extend that they use /proc if they notice a problem accessing
the kernel:  yes, at least for -current. There was some work in
the last months on this, so 1.4.1 might have less of that functionality.

Affected commands are in-tree ps and top.

Btw: don't confuse this with the Linux /proc. Linux  /proc is in
reality a /we_put_everything_into_this; the BSD /proc has only
process-related information. Generic kernel information is handled
by kernfs (mounted on /kern); some of you might have noticed that
/kern/msgbuf is used instead of "dmesg" inside installation miniroots,
or that the installation miniroot uses /kern/rootdev to mount itself
read-write.
