Since method property values are actually shell scripts (i.e., they are
executed like this: execle("/sbin/sh", "/sbin/sh", "-c", method_propval,
NULL, nenv)), there's not much choice but to display the method property
values as a whole.
To get a command name out of a method property value is not as simple as
you might think -- consider this:
/sbin/sh -c 'foo=;: ${foo:=bar}; echo $foo'
or
/sbin/sh -c 'env FOO=bar /lib/svc/method/.../foo'
No, noone should be writing method property values of that sort, but it
is possible. So you really need a human to look at the method property
values.
(Perhaps then using /sbin/sh -c to evaluate methods was a bad idea? But
it's certainly in keeping with the way things work in a Unix
environment.)
