Installed-Size
Sub-Package
Number
The Installed-Size field defines the size of the package once installed on a target system. This field is automatically calculated by the build process if it is not already defined in the package. Note that the size is currently calculated using a block size of 1024 bytes when most modern systems make use of 4,096 or more.
In most cases you should let the wpkg --build command compute this value. If you need to define some additional space. For example because you create some files after installation, then that space should be included in the Extra-Size field instead.
If defined by you, the field must be a valid decimal number defined in Kb.
Note: This field should probably not be defined in a control.info file.
