Released artifact doesn't load correctly for certain docker images

Environment

The released artifacts cannot be loaded correctly on certain platforms. I tried to install zpm-0.7.1.xml on docker image containers.intersystems.com/intersystems/iris-community-arm64:2024.1.

Reproduce

The output is

USER>set sc = ##class(%SYSTEM.OBJ).Load("/home/irisowner/zpm.xml", "ck")

Clues

Apparently the MODDIR variable in the .xml file is somehow evaluated to /usr/irissys/mgr/user/-28/. Not sure where the -28 comes from. In ASCII table, 28 (as decimal) is file separator. Not sure if it's related.

On the other hand, running the above command on native IRIS (macOS ARM64 version) works fine.
