At work we have a 386 system (used for accounting) running SCO Unix. I
changed the shell for root (in the /etc/passwd file), from '/bin/sh' to
'/bin/csh'. Boy did this cause problems. Everything works fine, until you
reboot the system. While the system is coming up (e.g. starting cron, print
services, etc.) is starts display the /etc/motd (i.e. message of the day) file.
After the system finally comes up, if you look at the /etc/systemid file it
contains the contents of the /etc/motd file prepended to what was originally in
the /etc/systemid file, that is the /etc/motd file is in the /etc/systemid file
with the original value of the /etc/systemid file at the bottom. Also, the
/etc/mnttab table is totally trashed, containing a lot of garbage that commands
like 'df' puke on.
On other Unix systems I have found that a lot of times the scripts in /etc that
are executed upon boot, don't contain the ":" or "!/bin/sh" at the top of them,
which tells them to execute using the Bourne shell; therefore, if they are
executed using the C-shell they crash. I looked through quite a few of them
on the SCO Unix system, but they appeared to be okay.
Has anyone else experienced this problem or know why it happens? Is there just
a badly formed script that I overlooked or what?
Your help is appreciated!!!

I think the problem is that SCO in their "WISDOM" looks at /etc/passwd for the root shell and executes that as the shell for startup. (When I added a "tset -r" in the /etc/profile every time I reboot, I get a TERM=(ansi) prompt at the bottom of the screen.) I would think that *nix would be smart enough to just default to /bin/sh to execute these scripts. Leave it up to SCO to screw it all up. #include std_disclaimer.h -- Mark A. Emanuele V.P.
