When using Guix as package manager on a foreign distribution (Pure OS Byzantium) and after installing some GNOME package (GNOME Web - Epiphany), it exposes some files, which are processed during the user's login resulting in a login failure.
Way to reproduce:
$ guix install epiphany
$ sudo reboot
After GDM appears, enter the user password.
Observed result: the screen turns black, then returns to GDM. (If GDM
is not installed and if the phosh service is enabled instead, the
screen remains black after unlocking the drive but turns on and off.)
Expected result: session starting as usual (utilising the host system
files).
Here is the part of the system log, which appears to be relevant
because it is different between the normal and affected login attempts.
I attach the full logs for reference.
