About to update to RedHat Enterprise Linux or CentOS 7.7? Beware!


There's a couple of caveats before upgrading to RHEL / CentOS 7.7.

1: Upgrading to latest RHEL 7 PCP package pcp-4.3.2-2.el7 gives several issues.

During installation/upgrade of pcp-selinux:

    Updating / installing...
    1:pcp-selinux-4.3.2-2.el7 ################################# [100%]
Failed to resolve allow statement at /etc/selinux/targeted/tmp/modules/400/pcpupstream/cil:83
semodule: Failed!

Followed by lots of selinux errors logged.

Workaround is to install 7.7's selinux-policy first

    yum update selinux-policy

or, if you've already updated,

    yum reinstall pcp-selinux

Documented in RedHat Bugzilla entry 1714101 

2: bind is updated from version 9.9 to 9.11. This breaks configurations in which the same zone file is defined in several views.

The solution is to use bind 9.11's "in-view xxx" in subsequent definitions of the same zone in different views.

The fix is described in detail here.
