==========
|
||
|
|
|
||
|
|
The scripts can generally just be run. Options can be set on the command line
|
||
|
|
or by exporting variables to override those present in lib/img-defaults. -h to
|
||
|
|
get help.
|
||
|
|
The image building scripts expect to be able to invoke commands with sudo, so if you
|
||
|
|
want them to run non-interactively, you should either run them as root, with
|
||
|
|
sudo -E, or allow your build user to run any sudo command without password.
|
||
|
|
|
||
|
|
Using the variable ELEMENTS\_PATH will allow to specify multiple elements locations.
|
||
|
|
It's a colon (:) separated path list, and it will work in a first path/element found,
|
||
|
|
first served approach. The included elements tree is used when no path is supplied,
|
||
|
|
and is added to the end of the path if a path is supplied.
|
||
|
|
|
||
|
|
By default, the image building scripts will not overwrite existing disk images,
|
||
|
|
allowing you to compare the newly built image with the existing one. To change
|
||
|
|
that behaviour, set the variable OVERWRITE\_OLD\_IMAGE to any value that isn't
|
||
|
|
0.
