Nice, I could just point my tool at it and it got some data (despite not
having ported it to openSUSE or riscv64 at all):

              nevra               |                 name                 
----------------------------------+--------------------------------------
 authbind-2.1.2-2.1.riscv64       | /usr/lib/authbind/libauthbind.so.1.0
 glibc-2.31-2.1.riscv64           | /lib64/libc-2.31.so
 jamin-0.95.0-259.1.riscv64       | /usr/lib64/ladspa/jamincont_1912.so
 ladspa-caps-0.4.4-4.2.riscv64    | /usr/lib64/ladspa/caps.so
 ladspa-pvoc-0.1.12-3.2.riscv64   | /usr/lib64/ladspa/pvoc.so
 libnuma1-2.0.13-1.1.riscv64      | /usr/lib64/libnuma.so.1.0.0
 segv_handler-0.0.1-161.2.riscv64 | /usr/lib64/segv_handler.so
 vde2-2.3.2+svn587-3.2.riscv64    | /usr/lib64/vde2/libvdetap.so
(8 rows)

This still looks rather manageable to me, so perhaps we can go ahead
with the removal of DT_INIT support on riscv64.

Thanks,
Florian
