It would be nice if usim.ini could support something like a %myname% variable; so that one could write:

   disk0_filename = disk_%myname%.img

And have it expand based on whatever the value of chaos.myname is. Then also have a -n FOO option to usim proper that can set chaos.myname accordingly.

This would allow reusing the same config for multiple instances easily without having to make a bunch of usim.ini files for each machine.

Might be better to do this using M4; then one could also support things like "%include foo" kind of directives. Which would be useful if one has a site, with multiple hosts, e.g, usim-ams-lm1.ini:

%include usim-amssite.ini
myname = AMS-LISPM-1

And where, usim-amssite.ini might contain:

sys_directory = ../sys
state_filename = usim-%myname%.state

prommcr_filename = ../sys/ubin/promh.mcr
promsym_filename = ../sys/ubin/promh.sym
mcrsym_filename = ../sys/ubin/ucadr.sym

hosts = ../sys/amssite/hosts.text

disk0_filename = disk-%myname%.img
