Reserving Additional Space on a Target System

You need to determine whether your package needs additional disk space on the target system. This space is in addition to the space required by the package objects. If so, create the space information file. This task is different than creating empty files and directories at installation time, as discussed in Defining Additional Objects to Be Created at Install Time.

The pkgadd command ensures that there is enough disk space to install your package based on the object definitions in the pkgmap file. However, a package may require additional disk space beyond that needed by the objects defined in the pkgmap file. For example, your package might create a file after installation, which may contain a database, log files, or some other growing file that consumes disk space. To be sure that there is space reserved for it, you should include a space file that specifies the disk space requirements. The pkgadd command checks for the additional space specified in a space file. Refer to the space(4) man page for more information.

Note –

Be certain that your space file has an entry in the prototype file. The file type should be i (for package information file).
