[vbox-dev] [PATCH] add redhat8_ks.cfg kickstart

Due to changes in RHEL 8, the redhat67_ks.cfg Kickstart script included in
the UnattendedTemplates directory does not work with CentOS 8. The patch
below adds a Kickstart script for RHEL 8 and CentOS 8, and makes other
changes to integrate the new script into VirtualBox. Following the pattern
for redhat67_ks.cfg, the new script is named redhat8_ks.cfg. All comments
in the new script are worded to mirror language and terms used in the RHEL
8 documentation; and all sections, commands, and options appear in the same
order in both the new script and the documentation.
The install command has been deprecated in RHEL 8. In regard to the install
command, the documentation states, "Use its methods as separate commands."
The cdrom command was retained and now serves to specify that installation
should occur from the first optical drive. The install command was removed
from the new script.
The auth command has been deprecated in RHEL 8. Passwords are shadowed by
default with sha512. The following auth command was removed from the new
script:
auth --useshadow --passalgo=sha512
The default SELinux policy is enforcing. The following selinux command was
removed from the new script:
selinux --enforcing
The documentation states, "Either the --vckeymap= or the --xlayouts= option
must be used" for the required keyboard command, suggesting an OR rather
than an AND. Nonetheless, both --vckeymap=us and --xlayouts='us' are used
in the new script. Many examples of this usage can be found, and it does
not appear to cause issues. The value "us" was specified to maintain
consistency with the value that was specified in the redhat67_ks.cfg script.
In order to comply with the order demonstrated in the syntax shown in the
documentation, the timezone command was changed as follows:
timezone@@VBOX_COND_IS_RTC_USING_UTC@@ --utc@@VBOX_COND_END@@
@@VBOX_INSERT_TIME_ZONE_UX@@
timezone @@VBOX_INSERT_TIME_ZONE_UX@@@@VBOX_COND_IS_RTC_USING_UTC@@ --utc@
@VBOX_COND_END@@
For the --plaintext option to the user command, the documentation states,
"If this option is present, the password argument is assumed to be in plain
text"; but it does not explicitly indicate plaintext is the default. The
--plaintext option was added to the user command as follows:
user --name=@@VBOX_INSERT_USER_LOGIN_SH@@
--password=@@VBOX_INSERT_USER_PASSWORD_SH@@
user --name=@@VBOX_INSERT_USER_LOGIN_SH@@
--password=@@VBOX_INSERT_USER_PASSWORD_SH@@ --plaintext
For the network command, DHCP is the bootproto method used by default. In
addition, due to a change in how network devices are named in RHEL 8, eth0
is not a valid device name by default; but the link keyword can be used to
specify the first interface with its link in the up state. The network
command was changed as follows:
network --bootproto=dhcp --device=eth0 --onboot=on
--hostname=@@VBOX_INSERT_HOSTNAME_FQDN_SH@@
network --device=link --onboot=on --hostname=@@VBOX_INSERT_HOSTNAME_FQDN_SH@
@
For the bootloader command, mbr is the default value for the location
option. The bootloader command was changed as follows:
bootloader --location=mbr --append="nomodeset crashkernel=auto rhgb quiet"
bootloader --append="nomodeset crashkernel=auto rhgb quiet"
The autopart command automatically creates partitions in accordance with
Red Hat recommendations. The value plain for the type option specifies
"Regular partitions with no LVM." The following two part commands were
changed to the single autopart command on the third line immediately below:
part / --fstype ext4 --size 6000 --grow --asprimary
part swap --size 1024
autopart --type=plain
Without the elfutils-libelf-devel package installed, post install scripting
failed to compile kernel modules for VirtualBox Guest Additions, resulting
in their failure to install. The elfutils-libelf-devel package was added to
the %packages section in order to resolve this issue.
Only the new Kickstart script has been tested, and it has only been tested
with CentOS 8. OS and Guest Additions both install. Full testing with RHEL
8 should be completed prior to integration.
I'm licensing this patch under the MIT license. Please review. Feedback is
welcome. Thanks!
