1.206.1. RHBA-2009:0484: bug fix and enhancement update
Note
This update has already been released (prior to the GA of this release) as FASTRACK errata RHBA-2009:0484
The setup package contains a set of important system configuration and setup files, such as passwd, group, and profile.
This updated setup package fixes the following two inconsistencies between the bash and the csh and tcsh profile scripts:
- in order to match the bash shell's default behavior and provide consistency across shells, csh files in the /etc/profile.d/ directory are not read when csh is loaded as a non-login shell.
- when using the csh or tcsh shell, the user's umask is now set exactly the same as it is for the bash shell. If a process owned by a user creates a file, the UID number of the user is 100 or greater, and the username and group name match, then the umask of the process will be set to "002". Otherwise, the umask will be set to "022".
In addition, this updated package provides the following enhancements:
- this updated setup package reserves the new "tss" User ID and Group ID, and the userid (UID) and groupid (GID) numbers (59:59), which should prevent accidental usage of that UID/GID pair by other packages and administrators. TrouSerS is an implementation of the Trusted Computing Group's Software Stack (TSS) specification.
- this updated setup package reserves the new "puppet" user ID and group ID, and the userid (UID) and groupid (GID) numbers (52:52), which should prevent accidental usage of that UID/GID pair by other packages and administrators. Puppet is an automated system administration engine that performs tasks such as adding users, installing packages, and updating server configurations based on a centralized specification language.
- this updated setup package reserves the new "pkiuser" user ID and group ID, and the userid (UID) and groupid (GID) numbers (17:17), which should prevent accidental usage of that UID/GID pair by other packages and administrators. The "pkiuser" user and group IDs are used in subsystems associated with the Red Hat Certificate System.
- this updated setup package reserves the new "vdsm" user ID and "kvm" group ID, and the userid (UID) and groupid (GID) numbers (36:36), which should prevent accidental usage of that UID/GID pair by other packages and administrators. VDSM service manages a single SolidICE node (VDS). It serves as a proxy for Virtual Machine creation, management, statistics, and log collection.
- this updated setup package reserves the new "oprofile" user ID and group ID, and the userid (UID) and groupid (GID) numbers (16:16), which should prevent accidental usage of that UID/GID pair by other packages and administrators. The "oprofile" user and group IDs are used by the OProfile program, a low-overhead, system-wide profiler capable of running transparently in the background.
Users are advised to upgrade to this updated setup package, which resolves these issues and adds these enhancements.
