I'm trying to install RedHat 8.4 on a workstation in an isolated network. Is there a way to do it without connecting to the web or a server on the same network ?

The GUI does not seem to provide the option to install from the DVD anymore in this version, and attempting to use a Kickstart file with repo --name="RpmPackages" --baseurl=file:///run/install/repo/my_repo adds a line in the additionnal repositories list but not as a main repository and does not allow the installation to proceed. The 'main' repository appears to have to be a network location as the GUI does not provide the option to use a file:// path, however this workstation can not connect to anything (first workstation in the isolated network).

Every kickstart example I have found uses an nfs or http server to provide the initial repository.

Is there a way to force an installation from disk or do i have to install a server on a different OS before I can actually start installing the target system ?

I've been trying to compile GDAL 3.2 on CentOS 8 (due to a java project requiring gdal bindings that should be provided by gdal32-java), however rpmbuild fails right at the start before I make any change:

$ rpmbuild --rebuild ../gdal32-3.2.3-1.rhel8.src.rpm
Installing ../gdal32-3.2.3-1.rhel8.src.rpm
error: line 23: Unknown tag: %pgdg_set_gis_variables

Note that the source RPM is from the pgdg-source-common repository provided by postgres at https://download.postgresql.org/pub/repos/yum/srpms/common/redhat/rhel-8-x86_64. All dependencies required by the spec file are installed.

The tag %pgdg_set_gis_variables in gdal32.spec appears only once (at the line where an error is reported) and seems to initialize some global variables used to retrieve other files/resolve dependencies.

By unpacking the file into SOURCES and commenting-out this tag - as well as manually setting the expected values that I see unused, I could get rpmbuild -ba SOURCES/gdal32.spec, however it fails at configure, presumably due to missing values that should have been set by %pgdg_set_gis_variables (+ In this case, I get an error that shows that there is an attempt to expand the tag despite its being commented-out).

Do you know where I could find a sample that provides this tag/How I could build this RPM ?
