Whenever this happens again on Solaris 10, not getting a service out of

I've traced one of those issues down to some kind of sqlite stuff
getting confused (which is used by smf(5) IMHO).
This is good info. Robert or Peter, do you want to add it to the
wiki? I feel like we should have a more extensive "Amanda on Solaris"
section, but I'm certainly unqualified to write it..
Solaris 10 is a whole new ball of wax for a sysadmin.
I've created a number of services, but still have a lot to learn. One
important thing to note is the whole chain of dependencies and run
levels that affect a service. You can write a simple service that has
no (or claims no) dependencies, but that isn't really the way they are
supposed to work. It's sort of like building error checking and
pre-conditions into code.
Just as an example, I cloned a system this week by replicating the boot
drive, moving the drive to another system, and replicating that back
over the boot drive. Then boot off CD and edit all the /etc identity
stuff. I forgot to remove some entries from /etc/vfstab where the first
system had a larger collection of drives. It booted up and none of the
services came up. It turns out that the file system is a dependency for
the multi-user run level, which in turn is a dependency for many of the
services. So, the extra file systems, that I didn't need, ended up
blocking all the services. On a Solaris 9 system, that would have just
flown by.
You can see the full list of dependencies for a service by doing `svcs
-l <service name>`. Of course, that's recursive. Some of those might
have dependencies as well. It's sort of like tracking the loading of
libraries and their dependencies with ldd.
