I'm trying to debug my startup scripts in rc2.d and rc3.d - during boot the system prints nothing to the console. Where does the output (stdout, stderr) from the scripts go?
The scripts do run, I know that,
Thanks,

take a look in /var/svc/log/
This is the area where all of the starup services/scripts put their output.
For the old style rc scripts you want to lookin the milestone logs:
rc2.d goes to milestone-multi-user:default.log
rc3.d goes to milestone-multi-user-server:default.log
a tail -f on these is pretty useful at boot time, since your the login prompt appears (and sshd comes up) before most of the rc2 and rc3 scripts run.
Thanks, to be a bit more specific, one of my favorite ways to debug startup scripts in the past was to place a "#!/bin/sh -x" in the first line fo the script so I could see everything happen. It appears that this output doesn't seem to be captured anywhere in the Solaris 10 boot process.
Output going to stderr and stdout by way of an echo statement seems to be captured, I created a file /etc/rc2.d/S99outputfoo that looks like this:
#!/bin/sh -x
echo I AM A JELLY DONUT TO STDOUT
echo I AM A JELLY DONUT TO STDERR >&2
echo I AM A JELLY DONUT TO DEVNULL >/dev/null
Which IIRC sends the second line to stderr, just to check to see if it was a matter of svc sending stderr to the bit bucket. But all I see in milestone-multi-user:default.log is:
Executing legacy init script "/etc/rc2.d/S99outputfoo".
I AM A JELLY DONUT TO STDOUT
I AM A JELLY DONUT TO STDERR
Legacy init script "/etc/rc2.d/S99outputfoo" exited with return code 0.
I expect to see something like:
+ echo I AM A JELLY DONUT TO STDOUT
I AM A JELLY DONUT TO STDOUT
+ echo I AM A JELLY DONUT TO STDERR
I AM A JELLY DONUT TO STDERR
+ echo I AM A JELLY DONUT TO DEVNULL
This might sounds bonkers (as it should do the same thing) but try this:
instead of:
#!/bin/sh -x
try:
#!/bin/sh
set -x
This has worked for me in the past.
Otherwise i've used newctty (to get round Sun bug number 1143634 - using response files in rc scripts), however it also sends the ouput back to the console again, as before:

I'm not sure if i still need newctty for Solaris 10 (for the pkgadd bug).

BTW I also seem to have heard there is a verbose output option to smf. I'm sure it's buried somewhere in the documentation.
