Bug#773704: libsys-hostname-long-perl: additional output of su command not filtered

[Christian Vieser]

Package: libsys-hostname-long-perl
Version: 1.4-2
Severity: normal

Dear Maintainer,

in case the home directory of user nobody doesn't exist, "su" creates
it and reports this action on stdout, like this:

# su -s /bin/sh nobody -c hostname
Creating directory '/nonexistent'.
myserver.example.com

The perl function hostname_long() concatenates these two lines in
reverse order, so the returned string value is

myserver.example.comCreating directory '/nonexistent'.

I suggest to ignore all possible additional output of "su" and only
return the last line. Of course it would be preferable to prevent
su from creating the directory at all, but I couldn't find a solution
for this.

Thank you very much,
Christian
