Add cloning of Ubuntu

Ubuntu installations may now be cloned

Add Ubuntu 22.04 diskless

Ubuntu 22.04 can now be diskless booted

Add missing scripting support to Ubuntu scripted installation

Ubuntu scripted installation did not fully have pre.d, post.d, and firstboot.d. Add these hooks for more consistent Ubuntu behavior.

Add netplan support to confignet

Confignet can now correctly configure netplan in Ubuntu installations

Add openbmc console support

For OpenBMC based systems, a new console method ‘openbmc’ is provided for better performance and security when working with such platforms.

Break out partitioning and package list for EL scripted profiles

Make customization of EL profiles easier by having the partitioning and package list as separate files for new profiles.

nodeattrib can now read from a file

A nodeattrib batch file can now be specified by nodeattrib -s

nodersync can now interact with a non-default interface

The nodersync command now has a -s switch consistent with nodeping and nodeshell.

Fix cloning to NVME boot devices

The cloning would fail when the target was NVME, this is corrected.

imgutil now has non-interactive operation

There is now a -y argument to imgutil to avoid being prompted by zypper or dnf

Improved Cooltera CDU sensor behavior

A broader range of firmware is now supported.

Improve imgutil capture warnings

Previously, a user would not be aware of missing parts of a clone until a test deployment. Now a number of key dependencies are checked and fail the capture if it is known the image would have challenges booting.

Improved discovery performance and fixes.

Discovery activity for known nodes is reduced. This particularly helps large systems with a collective. Also, a problem where discovery could be terminated due to a bad subscription has been fixed.

Improved collective behavior

Collective startup uses far less resources in large clusters. Collective members now skip scanning switches that are not relevant, per collective.managercandidates.

More graphical terminal support in stats

Stats can now specify a terminal format in ‘-f’. The default remains sixel, but iterm and kitty are now implemented:

kitty is compatible with konsole, kitty, and wezterm and is the most recommended. iterm may work in other terminals. sixel is the slowest and most likely to have glitches, but may work with some terminals that support neither iterm nor kitty.

Improve noderange collation in collate

Collate can now abbreviate numerical ranges and leverage bracket support to shorten the result. For example: grp[1:2,4],t3u[18:25,30],t4u[20:30],t5u[17:24,27:30]

Mitigate poor DNS behavior

Slow DNS behavior has long caused issues in confluent. Confluent now enacts an aggressive timeout and makes some formerly sequential name lookup activity concurrent.

Confluent now has server side rack layout API call

API users now have a call that can more easily organize rack location information, /noderange/[noderange]/layout.

Confluent 3.9.0 no longer has support for RHEL 7 as a management node

Confluent 3.9.0 will no longer support RHEL 7.x as a management node. Managing nodes running RHEL 7 is still supported.
