Upgrade not respecting packaged installer

[fernandezpayen]

During the upgrade process, "Install macOS Monterey 12.2.1" is packaged and deployed. However, we are noticing that once the computer has completed the upgrade, the computer is running 12.3. Somehow, the computer is upgrading to 12.3 during the upgrade process. Parameter 5 is specifically set to "12.2.1". The packaged installer is 12.2.1.

In addition, the startosinstall.log file is gone from the system after the upgrade is complete. We would like that file saved on the computer for review while testing the upgrade process.

Further investigation into this issue has led to a unique finding in the install.log. The devices that are going past the indicated macOS upgrade (12.2.1) are showing the following in the install.log file:

• osinstallersetupd[9778]: Disk image is mounted out of the kernel at /Volumes/dmg.PdZiQz

However, the devices that are going to 12.2.1 are showing that the installer disk was mounted:

• osinstallersetupd[7544]: Mount point /Volumes/Shared Support
• osinstallersetupd[7544]: mountDiskImageWithPath: /Applications/Install macOS Monterey.app/Contents/SharedSupport/SharedSupport.dmg

Is this something that has been seen by anyone else?
