Just wondering why in EL5’s base repo the latest supported mysql package is 5.5 and in EL6’s base repo it is 5.1? Seems strange to me.

(it is clear that the SCL of EL6 has version 5.5 but that implies a different update policy).

Because that is how Red Hat decided to handle MySQL in EL5. I agree with you that it seems strange … CentOS just rebuilds the upstream source code. They did it, we duplicated it.

In fact, the MySQL in EL5 is an SCL. It is the only SCL released for EL5
and it is different than the EL6 ones (path wise, etc).

BTW, I am sure they had their reasons, they would not have done it that way without good reasons as it is a fairly substantial change. I don’t know what those reasons are however.

Without knowing exactly the reasons – EL5 vs. EL6 are structural not so different (e.g. POSIX) that the reasons wouldn’t apply also to EL6. Anyway, it is like it is.

similarly, EL6 now has mdadm-3.3 whereas EL7 has mdadm-3.2 .

mdadm-3.3 supports the badblock log (bbl), whereas mdadm-3.2 doesn’t. This is something to consider – one could/should use EL6’s mdadm to create an md device on a EL7 system. This is future-proof in the sense that the EL7 kernel will then be able to use the bbl, and hopefully RH
will include mdadm-3.3 in EL7.1 .

best, Kay
