DDensity.? I thought there was a single command to make the system

Was it SYSGEN?
As near as I can tell SYSGEN only modifies a file (or two) but
does not copy any files to a new location.

No, SYSGEN is the CP/M command to initialize a blank, formatted disk with the
CP/M system:
“The SYSGEN transient command allows generation of an initialized disk
containing the CP/M operating system. The SYSGEN program prompts the console
for commands by interacting as shown...” (From
http://www.gaby.de/cpm/manuals/archive/cpm22htm/ch1.htm#Section_1.6.6).
SYSGEN puts the CP/M system files on a reserved (not visible) area of the disk.
It is a separate program, not a built-in command. On the Osborne (which I
used), CP/M was 4KB in size. You can use then use PIP to copy the other,
visible files.
Seems a bunch of crossed wires. SYSGEN is also a command on LDOS,
LS-DOS, versions of TRS-DOS (that were actually versions of LDOS
or LS-DOS) but with a totally different function.
I didn't now the command off the top of my head but I did know
that making bootable floppies under CP/M was not difficult. Just
like moving it to allow for different memory maps. Something else
that none of the other TRS-80 OSes can do.
