[9fans] cron and lib/profile

[gas]

Cron (w. host=local) does not seem to read $home/lib/profile, so all
the binds there are missing. Should it not behave as if the user logged
in and typed the command manually?

With host=local, the command runs in a namespace as in /lib/namespace.
If you need the bindings made in your lib/profile you can use the
explicit name of the CPU server as hostname.

In the latter case, rx(1) and rexexec(8) are used. Rexexec does:
execl("/bin/rc", "rc", "-lc", buf, nil);
to run the commands in it. (The -l flag causes rc to read lib/profile.)

whereas, if host is 'local', cron does:
execl("/bin/rc", "rc", "-c", buf, nil);

The I can't tell if the difference in behaviour is intended.  But you
can work around it that way.

This is left over from when localcron was a separate program.
Then it didn't even create a new name space.  It just ran as
the local user in the name space in which it started.

It would probably make sense to change cron to do:

		putenv("service", "rx");
		execl("/bin/rc", "rc", "-lc", buf, nil);

to be more like rexexec.  Perhaps $service should be
"cron", but "rx" seems okay.

Heiko, Russ - thanks. It works as expected with the explicit name. The
"local" made me somewhat confused; it just failed silently.
