Use case

It's desired with both an installation (zfssend) and upgrade (zfssend+be) image for a host.
Currently, this involves running "poudriere image" twice, doing a lot of duplicate work. (example: installing 160 packages twice)

Fix

It's desired to add new image types to fix this problem, and to make zfssend understand merging of them.
Argument:
zfssend+param1+param2+...
zfssend: alias for zfssend+full

• +full
  • Current implementation of zfssend
  • Append .full.zfs to image name
• +be
  • Current implementation of "zfssend+be".
  • Append .be.zfs to image name.

Currently, everything is echoed to STDOUT but does not seem to log it anywhere. Make "poudriere image" create a build log and write output there.

The command line option "-o" is described as follows, by the commands output:

Build a miniroot image as well (for tar type images), and
overlay this directory into the miniroot image

This seems to implicate it's only for tar type images, but it works perfectly fine with zfssend (and presumably, zrawdisk)###

Use case: I found that I wanted to do many scripted actions on an image after importing on a new host. This feature will allow performing the common ones on the image before export instead.

Use case: building images on a different system than the package builder.

Currently, poudriere image assumes there is a locally built package repository, and fails if it doesn't exist.

Solution: Allow specifying custom package repository using a command line option or environment variable.

Use case:

• One directory with common file structure for all images
• One (or several) directories with file structure for a specific image, or sets of images

Example:
poudriere image (...) -c /mnt/common -c /mnt/envs/staging -c /mnt/servers/someservername

would overlay files from the directories in the provided order.

poudriere imgage seems to intend to only set a hostname in rc.conf if it's specified:

# Set hostname
if [ -n "${HOSTNAME}" ]; then
	chroot ${WRKDIR}/world sh -c "echo \"hostname=${HOSTNAME}\" >> /etc/rc.conf"
fi

This variable may be set with the "-h" command line option, but there's a default value of "poudriere-image".

Consider not setting the default value.
Alternatively, consider not writing the default value to rc.conf if rc.conf already contains a hostname directive.
