Make Photon OS nightly builds great again

[dcasota]

Describe the bug

Hi Photon OS team,

The nightly builds of Ph5 use the same guid 21b41f5 since about a month ago. This only happens on x86_64 and it does not happen for Ph4.

Reproduction steps

classic make build

Expected behavior

non-repudiation of nightly builds

Additional context

No response

In Ph5 and common branch, https://github.com/vmware/photon/blob/5.0/support/spec-checker/check_spec.py introduced import license_expression with ab2f44b.
Hence for the docs, it has to be added e.g. as sudo pip3 install license_expression.

Ph5 nightly still uses a same guid f7e5808 since March 25th 2025.

In addition, when building ph5 with kernel 6.12.y (branch actually named as 6.0), to avoid the build issue AttributeError: module 'yaml' has no attribute 'safe_load' in "/root/common/support/package-builder/SourceConfigData.py", line 61, in _parseConfig config = yaml.safe_load(file).

add to the docs and run before make build:

sudo pip3 install license_expression
sudo pip3 install pyyaml
