Chapter 19. General Updates
Chapter 19. General Updates resource-agents-sap-hana shipped in an incorrect channel The resource-agents-sap-hana package has been available as part of the High Availability Add-On in Red Hat Enterprise Linux 6.7 and 6.8. However, asynchronous updates for this package were made available through the Red Hat Enterprise Linux for SAP HANA repository. Consequently, package updates on systems that do not enable both the Red Hat Enterprise Linux High Availability Add-On and Red Hat Enterprise Linux for SAP HANA repositories can fail. To avoid this problem, enable both the RHEL for SAP HANA and Red Hat Enterprise Linux High Availability channels in Red Hat Subscription Manager, Red Hat Network, or Red Hat Network Satellite prior to updating any applicable systems. If you do not have access to SAP HANA content, remove the resource-agents-sap-hana package by running the rpm -e command. (BZ#1334776) Incorrect information about the expected default settings of services in Red Hat Enterprise Linux 7 The module of Preupgrade Assistant that handles initscripts provides incorrect information about the expected default settings of the services in Red Hat Enterprise Linux 7 according to the /usr/lib/systemd/system-preset/90-default.preset file in Red Hat Enterprise Linux 7 and according to the current settings of the Red Hat Enterprise Linux 6 system. In addition, the module does not check the default settings of the system but only the settings for the runlevel used during the processing of the check script, which might not be the default runlevel of the system. As a consequence, initscripts are not handled in the anticipated way and the new system needs more manual action than expected. However, the user is informed about the settings that will be chosen for relevant services, despite the presumable default settings. (BZ#1366671) The default value of first_valid_uid in Dovecot has changed in Red Hat Enterprise Linux 7 Since Red Hat Enterprise Linux 7.3, the default value of the first_valid_uid configuration option of Dovecot has changed from 500 in Red Hat Enterprise Linux 6 to 1000 in Red Hat Enterprise Linux 7. Consequently, if a Red Hat Enterprise Linux 6 installation does not have first_valid_uid explicitly defined, the Dovecot configuration will not allow users with UID less than 1000 to log in after the update to Red Hat Enterprise Linux 7. To avoid breaking of the configuration, redefine first_valid_uid to 500 after the upgrade in the /etc/dovecot/conf.d/10-mail.conf file. Note that only installations where first_valid_uid is not explicitly defined are affected by this problem. (BZ# 1388967 )
