You can just type all the device names or use a shell loop when /usr/bin
is not mounted.

Yes, it is much faster to type all the device names than to even type
the command to generate them when there are a small number of device
names.

I wouldn't use jot for MAKEDEV'ing disks in practice :-).  Part of
my point is the new syntax for MAKEDEV is just as hard to remember
as the syntax for jot.  You would use it once or twice per millenium
after install more than about 8 drives at once.
