Package: login
Version: 1:4.0.16-2youpi
Severity: normal
Tags: patch upstream
Hi,
When booting with init=/bin/login, tty controlling sequences like ^C
or ^Z don't work. The incurred unfortunate effect is that one can't
interrupt the programs one runs (like ping, e2fsck, badblocks, ...).
This is because login doesn't initialize a session, while it should.
The attached patch corrects that, please apply.
Regards,
Samuel
