SMF was actually designed to *avoid* that sort of mess, but I guess to each his own. You might try setting the "logging" option for svc.startd. > 1) I wanted to make this mechanism more convenient by also > logging the information if the kernel was booted with the > "-m verbose" or "-v" option; how can a userland program > query the options passed to OI kernel? Looking at the source for svc.startd (usr/src/cmd/svc/startd.c), it looks like that just sets an internal flag and isn't exposed to applications. > 2) Also, echoing to /dev/console does not put the messages > into (local or remote) syslog files.

It's by design that multiple services are started in parallel and that each one writes to its own log file and that you don't get messages unless something is wrong. I suppose it'd be nice for someone to write a fancy SMF progress monitor to quell the anxiety of those who can't see no news as good news (I might be one of them ;-}), but I don't think reverting to a long colorful "foobar ... OK" list as in the Linux world is the right way forward. > 3) Is there a good way to differentiate the "physical" and > "serial" consoles, as to address and write to both of them > if available?
