Bug: Installer clobbers the NUKE_PATH environment variable

[yuanmich2]

Describe the bug

The installer completely overwrites the NUKE_PATH environment variable which can break a lot of Nuke environments.

Expected Behaviour

We should make reversible changes wherever possible. The installer should append to NUKE_PATH instead of clobbering it.

Current Behaviour

The installer just overrides the value of NUKE_PATH as described here:

deadline-cloud-for-nuke/install_builder/deadline-cloud-for-nuke.xml

Line 90 in f6ce5d7

<value>${nuke_installdir}</value>

Reproduction Steps

Run the installer on a linux machine. Check /etc/profile.d/deadline* and note the value of NUKE_PATH in it.

Environment

At minimum:

1. Operating system: Linux
2. Version of Nuke: n/a
3. Version of this package: 0.18.8
4. If this is from a version installed by the Deadline Cloud Submitter installer, then what version of the submitter installer? DeadlineCloudSubmitter-2025.02.06.0-linux-x64-installer.run

Hi! The NUKE_PATH of the individual installer is indeed different. Did you test if jobs would render correctly? From tests on my end, render jobs still work as intended.

Everything will work fine if you don't use any plugins. The problem is that every plugin needs to share the NUKE_PATH environment variable, but the installer is changing its value to only point to the deadline cloud submitter. The result is installing the submitter has a chance of breaking all other plugins.

The fix would be to append to NUKE_PATH rather than overwriting it.
