[buildd-tools-devel] Bug#589917: schroot: TERM environment variable is not preserved

[arno renevier]

Package: schroot
Version: 1.4.7-1
Severity: normal

Hi,
schroot(1) manual tells:

 default, the environment is not preserved, and the following environment
 variables are defined:  HOME,  LOGNAME,  PATH,  SHELL,    TERM  (preserved
 if  already  defined),  and  USER. 

But TERM variable, even when defined in my host environment is not preserved.
I think it was preserved in previous version, but I don't remember exactly
when.

my config is as follow:

[ia32]
description=Debian testing 32bits
directory=/srv/chroot/ia32
type=directory
users=arno
root-groups=root
root-users=arno                                                                                                            

regards,
arno
