Introduction to Git

Git is a source-code control system that allows multiple developers to work on the same project. Each developer has a copy of the repository on his workstation, and can check in changes to that repository and synchronize it with a central server. Other developers can then fetch those changes by synchronizing their local repository with the central one.

This documentation assumes that you already have a basic understanding of Git and source code control systems.

Introduction to Subversion

Subversion (also known as SVN) is a source-code control system that allows multiple developers to work on the same project. Each developer has a copy of some or all of the source code of the project on his workstation, and can check in changes to that repository which are then uploaded to a central server. Other developers can then fetch those changes by synchronizing their files with the repository.

When a new Virtualmin module is ready to be released, the following steps can be used to create, sign, and add them to the repositories.

There are three package types, and RPM and deb packages must be built on systems specific to those package types. We build RPMs on a CentOS 5 VM and debs on a Debian 5 VM. I usually build the wbm.gz package on the CentOS VM, though it can be built pretty much anywhere with a Webmin installation and the module you want to package.

In the examples below, I'll use the virtual-server module.

Can I run each service on a different machine?

Yes for some services, no for others.

It is possible to use LDAP for mail user configuration, though this is not a comprehensive solution. Many of the features of Virtualmin can be re-implemented manually on the mail server, using Webmin and Usermin, but per-domain spam/AV configuration is not possible in this setup. The other option is to use Virtualmins ability to run commands before or after creation/update/delete of user accounts. One could write a custom command that makes use of ssh to perform actions on a remote mail server.

FreeBSD has much shorter username limits than Linux, by default, and thus it is usually impossible to use the full domain name as the unique suffix for usernames. A full world rebuild is required to work around this issue, in order to insure that the kernel and all support tools agree on the longer username length.

FreeBSD has a limit of 16 secondary groups, and so permissions on homes can never be tighter than 751 (which makes directories list-able by all users that have a shell), because Apache must be able to access the public_html directory.

Note: Before upgrading, please beware that PHP 5.3, provided with Ubuntu 10.04, is not supported by several of the Virtualmin Professional Install Scripts. Since we have no control over those applications, the timeline for when they will work with PHP 5.3 is not under out control. We strongly recommend you check all of the applications you use, to be sure they will survive the upgrade, before moving from 8.04 to 10.04.

1. Plan for some down time (sorry, it's gotta happen with a distribution upgrade, regardless of Virtualmin being involved).

2. Convert your apt Virtualmin source to point to the virtualmin-lenny repo, instead of virtualmin-etch. Also add a virtualmin-universal source (this is new for lenny and will make upgrades and some other stuff easier/faster in the future; both on my side as the maintainer of the repos and on your side as the user). The virtualmin-universal source line looks like:
