Using the UserInstallation env breaks soffice.bin execution

[M0Rf30]

As in title.
I'm running unoserver a against custom soffice.bin.(cp-22.05.06)
It would be nice to pass or customize the default cmd line or, at least, remove the UserInstallation env.
Without it, a USER/.config/core/4 (not tied to /tmp) folder will be created and the soffice.bin will continue its execution flawlessly

Regards

How does it break it?
