NAME
appjail-ajspec —
AJSPEC file specification
DESCRIPTION
An AJSPEC is a file that contains parameters that specify how and where one or more images are downloaded, verified, and described.
The AJSPEC format is the same as described in appjail-template(5) with a subtle difference: required parameters are treated the same as normal parameters.
Although AJSPEC files have the same format as a Template, you should not use appjail-config(1), but rather appjail-image(1), which is more capable of editing which parameter and how.
PARAMETERS
The following are the parameters that made up the AJSPEC file. If Multiple is Yes, the parameter can be specified more than once. If Optional is Yes, the parameter is optional for the import and update subcommands in appjail-image(1).
<tag>.name
Image name. Although it is optional it is highly recommended to have it set as it is not, the user will have to specify one when importing.
Optional: Yes
Multiple: No
<tag>.timestamp.<arch>
Timestamp specifiying when the image was last updated.
Optional: No
Multiple: No
<tag>.maintainer
In charge of maintaining the image and everything related to it.
Optional: Yes
Multiple: Yes
<tag>.comment
One-line description
Optional: Yes
Multiple: No
<tag>.url
Home page project or a website that provides more information about the image for the specific tag.
Optional: Yes
Multiple: No
<tag>.description
Long description.
Optional: Yes
Multiple: Yes
<tag>.sum.<arch>
Checksum.
Optional: No
Multiple: No
<tag>.source.<arch>
Sites where the image can be downloaded. If the first one fails, appjail-image(1) will try the second one and if it fails, it will try the third one, and so on.
Thought this as a list and each source is an element. appjail-image(1) simply makes an attempt sequentially, but the way the list is sorted resides in the IMAGE_DOWNLOAD_METHOD parameter.
Optional: No
Multiple: Yes
<tag>.size.<arch>
Compressed image size.
Optional: Yes
Multiple: No
maintenance
