Another question that probably should be answered first is
that why pkexec (whatever that is) checks against /etc/shells
and if that’s correct.
On systems where I don’t have root, I tend to install things
including a shell into ~/.etc/bin/ and then ofc also put it
in $SHELL… for GNU screen.
I’d be really appreciative if I did not have to add extra
nōn-canonical paths to /etc/shells for bugs in unrelated
software.
Thanks,
