Mmmh, I don't think we can assume that sudo is installed, just because
we are within an sudo environment (with $SUDO_USER set).
Maybe we are inside a chroot environment and we entered by using sudo
from the outside. Package sudo is *not* necessarily installed *inside*
the chroot environment...
Oh, I see. More generally, this is an argument against the whole
'switching-the-user' point: the same user pointed by $SUDO_USER isn't
guaranteed to exist inside the chroot.
After rebuilding apt-listbugs with your proposed modification,
I enter the chroot environment (B50shell_pdeb hook script),
Thanks for the explanation, I was really puzzled by the mysterious
behaviour :)
In http://www.inventati.org/frx/progs/scripts/B50shell_pdeb I read:
/bin/bash < /dev/tty > /dev/tty 2> /dev/tty
Redirecting to/from the tty is evil, and chaining such
redirections is double evil for sure. Or is it evil^2 ? Well, anyway too
much evilness to defeat, I don't think there's a simple workaround for
it (for some meaning of 'simple').
(even though I don't understand the use of the $n variable in "read p v
n"...)
Oh, nothing (actually, it stands for 'null' or 'notcaringabout'), just
compulsory scripting for capturing the tail (if any) and not clobbering
the previous variable. Or if you feel like:
test -n "$n" || continue # These aren't the droids you're looking for
Ciao,
Gian Piero.
