Weekly Changes – 14/11/2022

Again this week the majority of changes are related to the new Ubuntu installer which is edging closer to being ready for general testing. Here are all the details…

Hardware Monitoring

The LCFG hwmon utility now ignores lustre read-only mounts when reporting failed drives.

fstab component

The new LCFG fstab component for Ubuntu is currently undergoing testing. This week sees the support for free partition sizes restored. Also, the new showdisks method now completely ignores all read-only drives (e.g. CD/DVD).

file component

With the new Ubuntu installer it is possible to configure files using the LCFG file component during the baseinstall phase (which is inside the recently established chroot). To use that facility the relevant LCFG tag must be added to the install-context specific resource – file.files[install] This is used to initialise various important locale configuration files.

LCFG installbase profile

With the new Ubuntu installer the LCFG installbase profile which is used to bootstrap the system is dependent on the bios boot mode (UEFI or legacy). To support this there is a new header – lcfg/options/select-installbase.h – which is included by the lcfg/options/boot-legacy.h and lcfg/options/boot-uefi.h headers. It may be included several times to allow overriding of the boot mode.

Note that if you use a local installbase profile (e.g. diceinstallbase-ubu2004) you may need to make some changes, the simplest solution is to specify that profile using the LCFG_INSTALLBASE_STUB macro. See the recent blog article for details.

Ubuntu Installer

The LCFG resources for the new Ubuntu installer are now fully integrated into the standard headers. This can be tested by defining the USE_NEW_INSTALLER macro at the top of an LCFG profile. We will soon be providing instructions for those outside of Informatics who would like to test the new installer for themselves.

Changes to headers and package lists

Members of the Informatics Computing team can browse all the changes to the headers and package lists.
