Use ldd on any service binary to see that it's linked against a separate distro. (It's best to use the ldd from the corresponding platform).

There are actually three distros on each host. Current runtime platform, previous runtime platform, centos platform.

For cases where you might not know which ldd will actually work, I like to use patchelf or readelf to get the interpreter then use the —list arg directly. That way it always actually gives correct results, using a different loader can change the selected library paths even if it thinks it works. One-liner would be approximately $(patchelf —print-interpreter tgt) —list tgt My apologies if the dashes became an em-dash or similar, on a phone.
