[Users] Fedora-3x template packages

[Denis Silakov]

You clone the repo inside the rpmbuild/SOURCES folder, so you get all sources inside rpmbuild/SOURCES/fedora-32-x86_64-ez folder, not inside rpmbuild/SOURCES itself.

Just copy the files to the SOURCES folder directly, e.g.:
vrpmbuild/SOURCES
# cd rpmbuild/SOURCES
# git clone -b dist-vz7-u15 https://src.openvz.org/scm/ovzt/fedora-32-x86_64-ez.git
# cp fedora-32-x86_64-ez/os*  fedora-32-x86_64-ez/*packages .
...

Also make sure that there no other files in rpmbuild/SOURCES, otherwise the template can pick up them.

The root of the problem is that template authors are quite lazy to declare every source file separately in spec, so the spec looks for sources in a rather tricky way:

%define sources_lst() \
%((cd %_sourcedir;\
s=1;\
for tmpl in %1; do\
sources=$tmpl"_*";\
for file in $sources; do\
echo Source$s: $file;\
s=$((s+1))\
done;\
done))\
%nil

%define templates_list() %((cd %_sourcedir; for f in *_packages; do echo -n "${f%_*} "; done))

The latter command scans _sourcedir recursively so it finds *_packages files even in subfolders. But the former macro doesn't look into subfolders so at least os* files are missing.

I am evidently still missing something. Building and installing an rpm
ran without errors:

# cd rpmbuild/SOURCES
# git clone -b dist-vz7-u15 https://src.openvz.org/scm/ovzt/fedora-32-x86_64-ez.git

# cd
# rpmbuild -bb rpmbuild/SOURCES/fedora-32-x86_64-ez/fedora-32-x86_64-ez.spec
# yum localinstall rpmbuild/RPMS/noarch/fedora-32-x86_64-ez-7.0.0-1.vl7.noarch.rpm

However, the resulting rpm contains no os files:

# rpm -ql fedora-32-x86_64-ez-7.0.0-1.vl7.noarch
/vz/template/fedora/32/x86_64/config/app/*/default
/vz/template/fedora/32/x86_64/config/app/*/default/description
/vz/template/fedora/32/x86_64/config/app/*/default/release
/vz/template/fedora/32/x86_64/config/app/*/default/summary
/vz/template/fedora/32/x86_64/config/app/*/default/version

and container generation of course fails:
# prlctl create F32 --vmtype ct --ostemplate fedora-32-x86_64
Creating the Container...
Failed to register the CT: PRL_ERR_VZCTL_OPERATION_FAILED (Details: Error:
Unable to find ostemplate: fedora-32-x86_64
Creation of Container private area failed)
Failed to create the virtual machine.


What am I missing?
