# vpkg-provides.sh is part of RPM, the Red Hat Package Manager.
|
|
|
|
# vpkg-provides.sh searches a list of directories (based on what OS
|
|
# it's being executed on) for shared libraries and interpreter files
|
|
# that have been installed by some packaging system other than RPM.
|
|
# It then generates a spec file that can be used to build a "virtual
|
|
# package" that provides all of these things without actually
|
|
# installing any files. The spec file in effect tells rpm what it
|
|
# needs to know about operating system files which are not under rpm
|
|
# control. This makes it much easier to use RPM on non-Linux systems.
|
|
|
|
# By default the script also generates a %verifyscript (with hard
|
|
# coded $shlib_dirs, $ignore_dirs values) which will check that the
|
|
# checksum of each file in the directories searched has not changed
|
|
# since the package was built.
|
|
|
|
# Comments: This script is a quick hack. A better solution is to use the
|
|
# vendor's package management commands to actually query what's installed, and
|
|
# build one or more spec files based on that. This is something
|
|
# I intend to write, probably in perl, but the need for something like this
|
|
# first effort was great, so I didn't want to wait until the better solution
|
|
# was done.
|
|
|
|
# The complete specfile will be sent to stdout.
|
|
|
|
# you will need to create a spec_header for the virtual package. This
|
|
# header will provide such specfile information as:

%description
|
|
This is a virtual RPM package. It contains no actual files. It uses the
|
|
\`Provides' token from RPM 3.x and later to list many of the shared libraries
|
|
and interpreters that are part of the base operating system and associated
|
|
OS packages for $osname.
|
|
|
|
This virtual package was constructed based on the vendor/system software
|
|
installed on the '$osname' machine named '$hostname', as of the date
|
|
'$date'.
