It installs: /opt/rh/nodejs010/root/usr/lib64/libcares.so.2 /opt/rh/nodejs010/root/usr/lib64/libcares.so.2.0.0 but causes packages depending only on libcares.so.2()(64bit) to not install c-ares, that installs: /usr/lib64/libcares.so.2 /usr/lib64/libcares.so.2.1.0 and provides libcares.so.2()(64bit) One example problem is that installing nodejs010-c-ares and then sssd has the side effect of sssd not installing c-ares.
nodejs010 has been EOL for ages and this bug is fixed in newer releases.
