[opennms-devel] OpenNMS Lists FAQ

Gang:

With the new year having arrived I thought we could use a little  
mailing list FAQ. So I stole the one Tanner Lovelace maintains for  
TriLUG and modified it to work for OpenNMS.

I'll send this out once a month, and regulars, please ignore. Also  
please excuse the multiple posts, one to each list, for those of you  
who subscribe to more than one.

The OpenNMS FAQ
Maintained by Tarus Balog <tarus(at)opennms.org>,
v1.0, 01 Jan 2005

The OpenNMS mailing lists have become rather successful as a channel  
for discussion of all aspects of the OpenNMS project and application.   
As is often a result with such lists, increased in the volume of  
traffic has prompted users to call for a FAQ to help maintain the  
signal-to-noise ratio. If you would like any help from the OpenNMS  
mailing list, this is the place to start!

[opennms-devel] Suggestion: Changing packages to *not* run the installer

Hey all,

I had part this discussion with brozow <at>  over IM a day or two ago, and I 
wanted to run it by everyone else on this list.

I'm significantly interested in changing the packages that we produce 
to *not* run the installer when the packages are installed.  My 
reasoning is below and I'm interested in people's comments and whether 
you agree or disagree.

I have two main reasons why I would like to do this:

1) Prevent the opennms packages from being partially installed if an 
error occurs in the installer.  Also make it easier for the user to 
re-run the installer if they do run into an error.
2) Make the installation more configurable, particularly in terms of 
not being so strict about OpenNMS's dependencies and where they live 
(e.g.: Tomcat).

There is also the side-effect of removing a lot of the complexity from 
the existing packages, particularly the opennms.spec.in file that is 
used for building the RPMs.

There are a lot of things that can cause it the Installer to fail, and 
I'd rather have it fail when the user can easily restart it instead of 
leaving a partially-installed RPM.  Here is a list of some of the 
common problems that users can get now (or ones that they will get when 
they upgrade to 1.1.5--the last three checks have been added to the 
installer since 1.1.4):

It sounds good. We hope with 1.3 to have an installer like Gallery.

For those of you that don't know, Gallery is a PHP app for publishing  
pictures online. I just upgraded from CVS (don't ask) and the admin  
page checked all dependencies and let me know what I needed to change.

It was slick.

I'll let Matt weigh in, but for me, +1

I like the idea and leaves lots of ideas open for custom installers.  I 
am curious about the upgrade process.  Would the opennms.sh script 
check to see if there had been an upgrade and prompt to run the 
installer?  With this new process the installer can be very wizardish 
and perform configuration changes as needed.

The more I think about this the better I like it.  +2 ;-)

This is very do-able, and a good idea.  We could have the post-install 
script of the RPM, .deb and other packages touch a file, and then have 
opennms.sh check for the existence of that file.  When the installer 
successfully runs, it will delete the file.

	Thanks,

This is already on the "roadmap" for the Debian packages.[1] Whether 
OpenNMS is ever uploaded to Debian contrib or not, I would still like 
them to conform to Debian policy/best practice as much as possible. This
is not feasible without dropping the invocation of the installer during 
postinst.

+1

[1] I was my intention to hold off until after 1.2 was released.
