[Pkg-sysvinit-devel] Bug#699566: sysvinit: handle ischroot more gracefully

[Yves-Alexis Perez]

Package: sysvinit
Version: 2.88dsf-39
Severity: normal

Hi,

this is more or less the same thing as #665827: sysvinit postinst use
ischroot to detect if it's in a chroot, but it doesn't correctly test
the return value.

ischroot returns 0 if a chroot is detected, 1 if not, and 2 if it failed
to do the detection. It's a bit unfortunate, because usually people do
stuff like: ischroot && foo.

But usually when you fail to detect that you're in a chroot, it's
because you're in one but you're prevented to detect it. In those case,
I think it should be safer to *not* try to kill 1 because it won't work.

Regards,
