fix for off-by-one in setting command title for init none

Description Kirill Kolyshkin 2006-04-06 15:09:49 UTC 
SysVinit version 2.86 have a problem in its code that leads to 
incorrectly displaying init name in process list (and in 
/proc/1/cmdline) -- it is shown as 'ini'. This was observed inside an 
OpenVZ's VPS. See http://bugzilla.openvz.org/60 for more details.

Patch fixing this is attached. Note that 2.85 does not have such bug.

Similar bugs found, filed and fixed in Debian and Gentoo. I have also sent it
maintstream to sysvinit maintainter(s) but never got a response back.

Hm, it seems quite possible that this could happen (especailly compared to the
2.85 code), however, I'm not actually seeing this in practice on any machine I
have access to. Certainly, your 'ini' example doesn't occur.

I'm curious how this could trigger only in OpenVZ. Do you invoke init
differently there?
Comment 3 Bill Nottingham 2006-05-10 16:06:28 UTC 
Added in 2.86-4.
Comment 4 Kirill Kolyshkin 2006-05-10 16:14:49 UTC 
Probably the thing is in ordinary Linux you usually run kernel with a lot of
parameters, and the ones which kernel itself can not recognize are being passed
to init. In OpenVZ, we just execute /sbin/init in a newly created virtual
environment without passing any arguments to it.

Package name is now sysvinit in latest Fedora.
