[Bug 1491102] [NEW] [FFE] add mdadm and lvm2 to cloud image

 

Public bug reported:

In order to make use of raid and lvm functionality that is being added
to curtin, we need to have mdadm and lvm2 packages available.  curtin is
able to install the packages, but that is less desireable than having
them already available inside the image.

This bug is a feature freeze exception to add mdadm and lvm2 to the wily
cloud-image seed [1].

== general risks ==
Adding these packages will add ~ 5M total to the cloud image installed system.

== mdadm risks ==
mdadm recommends on default-mta. So addition of this package to the cloud image means also adding an unconfigured mta (postifx). There is some discussion on this topic from ubuntu-devel at [2].

Additionally, its possible presence of this package could cause issues.
It installs udev rules that could misfire.  Any such issues encountered
really should be fixed anyway, rather than just hoped to not be hit.

== lvm2 risks ==
Similarly to mdadm, lvm adds udev rules and could raise cause problems.
As with mdadm, any such issues really ought to be fixed any way.


== general information ==
The reason this is proposed for inclusion into the cloud-image is 2 fold
a.) the maas ephemeral images are created from the cloud-image.  so packages in the cloud-image are then available in the install environment for maas.  We dont want to add differences between these installation sets.
b.) it is not unreasonable to add these packages to the cloud image.  It is not at all farfetched that someone would use lvm or raid in a "cloud" environment, so they're not entirely wasted space there.
