Up until now I wasn't aware of an "abnormal" way to bring a system down. The only other way that I know happens when init 0 or init 5 hang and you eventually get mad and yank the power cord. Which means that your script did nothing. :-) > Would this also work for scripts which change the > shutdown logic of the OS itself?

I'm only aware of two facilities. smf which can disable the services one by one (svcadm enable/disable) or in the cases of init 5 etc... stop everything or the old method with scripts in /etc/rc?.d linked to /etc/init.d. > Back in Solaris 8/9/10, the /etc/rc0 script was THE > logic which led to system halt or reboot (sans the > reboot/halt/uadmin commands themselves).

I don't have a Solaris 10 box anymore so I have no clue what is in the rest of /etc/rc0.d. Can you post the complete script with ! at the beginning of the lines that contain your code and not Sun's code? You may want to dig into the code at src.opensolaris.org. This is probably the original script: http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/initpkg/rc0.sh in which case it looks like you need to start parsing lsvcrun. http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/cmd/svc/lsvcrun/lsvcrun.c alan -- This message posted from opensolaris.org _______________________________________________ sysadmin-discuss mailing list sysadmin-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/sysadmin-discuss
