When you write something like this, can you accompany it with a
reference? The essential package util-linux's man page seems to
contradict whatever it was you found and read:
-, -l, --login
Start the shell as a login shell with an environment
similar to a real login:
[ … four bullet points … ]
-m, -p, --preserve-environment
Preserve the entire environment, i.e., do not set HOME,
SHELL, USER or LOGNAME. This option is ignored if the
option --login is specified.
