The prototype File

For example, this case study uses the hierarchical layout of the package objects shown in the figure below.

Figure 5–1 Hierarchical Package Directory Structure

The package objects are installed in the same places as they are in the pkg directory above. The driver modules (sst and sst.conf) are installed into /usr/kernel/drv and the include file is installed into /usr/include/sys/scsi/targets. The sst, sst.conf, and sst_def.h files are absolute objects. The test program, sstest.c, and its directory SUNWsst are relocatable; their installation location is set by the BASEDIR parameter.

The remaining components of the package (all the control files) go in the top directory of the package on the development machine, except the sed class script. This is called devlink.tab after the file it modifies, and goes into etc, the directory containing the real devlink.tab file.

From the pkg directory, run the pkgproto command as follows:

find usr SUNWsst -print | pkgproto > prototype

The output from the above command looks like this:

d none usr 0775 pms mts
d none usr/include 0775 pms mts
d none usr/include/sys 0775 pms mts
d none usr/include/sys/scsi 0775 pms mts
d none usr/include/sys/scsi/targets 0775 pms mts
f none usr/include/sys/scsi/targets/sst_def.h 0444 pms mts
d none usr/kernel 0775 pms mts
d none usr/kernel/drv 0775 pms mts
f none usr/kernel/drv/sst 0664 pms mts
f none usr/kernel/drv/sst.conf 0444 pms mts
d none SUNWsst 0775 pms mts
f none SUNWsst/sstest.c 0664 pms mts

This prototype file is not yet complete. To complete this file, you need to make the following modifications:

• Insert the entries for the control files (file type i), because they have a different format than the other package objects.

• Remove entries for directories that already exist on the target system.

• Change the access permission and ownership for each entry.

• Prepend a slash to the absolute package objects.

This is the final prototype file:

i pkginfo
i postinstall
i preremove
i copyright
e sed /etc/devlink.tab ? ? ?
f none /usr/include/sys/scsi/targets/sst_def.h 0644 bin bin
f none /usr/kernel/drv/sst 0755 root sys
f none /usr/kernel/drv/sst.conf 0644 root sys
d none SUNWsst 0775 root sys
f none SUNWsst/sstest.c 0664 root sys

The questions marks in the entry for the sed script indicate that the access permissions and ownership of the existing file on the installation machine should not be changed.
