Description

I've tried to search in Maloo for any results of b_es6_0 client with Rocky9.x distribution and got nothing but several failed node-provisioning. Meanwhile Yu Jian pointed out to some sessions with Rocky9 clients:

https://testing.whamcloud.com/test_sessions/447310ef-dc22-491f-843f-6a213d75774e

In both clients are reported as 'RHEL9.4' and that is why search by Rocky9.x distribution doesn't work it seems. So Rocky9.x distributions are not reported correctly in Maloo for some reason. 

btw, 'Rocky8.x' reported quite well
