- A regular expression, which was used to match the name of the master bond device in the grep utility, was incorrect. Consequently, network scripts did not properly handle lines in interface configuration containing comments and the ifup-eth command failed to activate slave devices. This update provides an updated regular expression for grep and ifup-eth now works as expected in the described scenario.

- In Red Hat Enterprise Linux 6.4, a master device was always started after its slaves while using Mode 6 bonding. As a consequence, bonded interfaces were unusable. This update ensures the master device is always set up before its slaves and Mode 6 bonding now works as expected.
- Previously, mounting of the /proc directory in the initrd script did not take into account options set in the /etc/fstab file. As a consequence, /proc was not mounted with the specified options. With this update, /proc is now re-mounted in the rc.sysinit script, which ensures it is mounted with the specified options.
- Previously, initscripts called the nmcli utility to stop the interface even if it was not managed by NetworkManager at the time. As a consequence, the interface was stopped, but the output of nmcli stated the action had failed. After this update, nmcli is no longer called when NetworkManager is not handling the interace, for example when it has failed, is disconnected, unamanaged or unavailable. As a result, the output from nmcli now matches the real result.
- If assigning an IP address through the Dynamic Host Configuration Protocol version 4 (DHCPv4) failed, initscript exited with an error. As a consequence, static IPv4 and IPv6 addresses were not set if DHCPv4 failed. The option IPV4_FAILURE_FATAL has been added to let the user decide whether the script should continue or exit when DHCPv4 fails. Additionally, if set to "no" and DHCPv6 is enabled in the configuration file, initscript tries to get an IPv6 address even if DHCPv4 fails.
- After sending the TERM signal, the killproc() function always waited $delay seconds before it checked the process again. This waiting was unnecessary and with this update killproc() checks multiple times during the waiting delay. As a result, killproc can continue almost immediately after a process ends.
- Previously, initscript did not follow the order of mounts specified by the administrator, because some mount types were prioritized. As a consequence, a subdirectory could be mounted before its parent directory. After this update, NFS, the Common Internet File System (CIFS), the Server Message Block (SBM) and other mount types are the last to be mounted. As a result, the mounts in the /etc/fstab file are processed in the right order.
- Previously, the securetty utility always tried to open the /etc/securetty file in read and write mode. As a consequence, on a read-only root filesystem, this led to failure and the file was not modified even if the TTY had already existed. With this update, securetty now checks whether the /etc/securetty file needs to me modified and exits if it does not. As a result, securetty now works correctly on a read-only root filesystem.
- Prior to this update, users were not informed when an Address Resolution Protocol (ARP) check was performed successfully. As a consequence, the users could be confused about the time needed to load the interface. With this update, a message is printed after every ARP check thus preventing confusion.
- Previously, initscripts documentation contained no information about the rule-* files. As a consequence, users did not know how to set routing rules for IPv6 addresses. This update adds documentation for the rule6-* files to the sysconfig.txt file.
- Previously, users were not aware of the /etc/init/*.conf files being overwritten after every update with the default values. A comment has been added to the /etc/init/*.conf files to inform users these files should not be modified and to use the *.override files instead.
- With this update, configuration options for Dynamic Host Configuration Protocol version 6 (DHCPv6) have been applied to the /etc/dhcp/dhclient6-<iface>.conf files. Options for both DHCPv4 and DHCPv6 in the /etc/dhcp/dhclient6-<iface>.conf are now applied.
