Fedora server implementation straw man

ok, so I figure I will see if I can't get some discussion going on
implementation plans. Here's a straw man proposal for everyone to knock
holes in and propose better ways to do our implementation. ;)
* Our deliverable will be a iso image similar to the current netinstall
iso image. It will be that + all packages needed to install/deploy
our featured roles and base things they need. This will allow
installing from the net or using the iso stand alone to install
* We add comps groups for each featured server role we support. So, for
example: 'server-freeipa'. This comps group has all the packages
listed we want to install to setup the role as we determine is best.
This may include packages that are not direct dependencies on the
* The roles use cockpit to manage and configure the server role post
install. If there's a way (not sure if there is), we could look at
adding a anaconda 'spoke' for the server install that runs this at
install time for folks that want to configure then? Or on firstboot.
* We create a new fedora-server-$role package for each role. This role
package contains the 'glue' we add to turn this into a fedora server
role from just a install with the packages and local config. We will
need to come up with guidelines and what these packages will contain,
1 A way to express what items should be monitored when the role is
installed/running. Perhaps /etc/server/$role/monitoring/ports and
processes and such.
2 A way to express data that should be backed up if you want to
backup the role. Perhaps /etc/server/$role/backups/datadirs and
configdirs or databases.
3. We may want to change systemd presets to indicate things that
should be running/enabled/etc when the role package is installed.
4. Anything else we need to impement an "API" for roles. Are we going
to define this soon?
5. We can tie this package to specific versions of requirements. So,
for example, if there's a new freeipa update and we haven't valided
fedora-server-freeipa with it, the requirement can be on the older
version and the users will not be updated until we push an update to
6. We setup specific bodhi requirements (like critpath) for server
role packages, requiring specific testing before they can go stable.
7. We may have a fedora-server-base or fedora-server-common package
to contain common/base stuff all roles need/user and make the role
packages require it. We would need to be very careful about updates
of this however.
* Users can install fedora-server-freeipa via yum/dnf after the fact,
or via the iso image/anaconda.
* Users can decide they don't care about our valueadding/glue and
remove fedora-server-freeipa and it will just go back to a machine
with all those packages installed (ie, uninstalling shouldnt
hopefully do anything other than allow them to remove required
packages and ignore our old glue).
ok. Poke holes away. ;)
