    Respect `db_home` setting even for SYSTEM/Microsoft accounts
    
    We should not blindly set the home directory of the SYSTEM account (or
    of Microsoft accounts) to `/home/<name>`, especially
    `/etc/nsswitch.conf` defines `db_home: env`, in which case we want to
    respect the `HOME` variable.
