Ben Nemec 01a0dbf7c0 Remove unnecessary dkms install from base 
The use of dkms in base was actually removed long ago in
Ic2c345bf9f0738dadae611194e263d3a5d424a3e and it is creating an
unnecessary dependency on EPEL for the centos elements.

base

This is the base element.

Almost all users will want to include this in their disk image build, as it includes a lot of useful functionality.

The DIB_CLOUD_INIT_ETC_HOSTS environment variable can be used to customize cloud-init's management of `/etc/hosts`:

  • If the variable is set to something, write that value as cloud-init's manage_etc_hosts.
  • If the variable is set to an empty string, don't create manage_etc_hosts setting (cloud-init will use its default value).
  • If the variable is not set, use "localhost" for now. Later, not setting the variable will mean using cloud-init's default. (To preserve diskimage-builder's current default behavior in the future, set the variable to "localhost" explicitly.)

Notes:

  • If you are getting warnings during the build about your locale being missing, consider installing/generating the relevant locale. This may be as simple as having language-pack-XX installed in the pre-install stage
  • This element ensures /tmp/ccache will be available in the chroot during the root, extra-data, pre-install, install and post-install stages. /tmp/ccache is unavailable during block-device, finalise and cleanup stages as it will have been automatically unmounted by then.
