Opera on Fedora 31
To work around Opera not starting on Fedora 31 I linked the libhwloc.so.5->libhwloc.so.15. Maybe one should also copy libhwloc.so.5 from CentOS7 (kantine) instead of linking the new one.
Probably also the new Opera 2020 will not depend on libhwloc.so.15, because their webpage claims to support RHEL7, but not RHEL8 and even RHEL8 seems to have libhwloc.so.5 instead of .15.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
