NetBSD zaphod 1.6.2 NetBSD 1.6.2 (ZAPHOD) #0: Sat Jun  5 04:50:05 PDT 2004     dave@arthur:/usr/src/sys/arch/i386/compile/ZAPHOD i386

>Description:
Attempting to create a package with pkg_tarup while a nonroot user, the following happens:

zaphod:~$ pkg_tarup foobar
Becoming root@zaphod to create a binary package
/usr/bin/su Password:
Illegal variable name.
zaphod:~$ 

This does not happen when the user is root (ie, using sudo), but it is rather annoying.
>How-To-Repeat:
See above
>Fix:
It seems clear to me that the following section of code in the pkg_tarup script is at fault:

if [ `${ID} -u` != 0 ]; then
        ${ECHO} "Becoming root@`/bin/hostname` to create a binary package"
        ${ECHO} -n "`${ECHO} ${SU} | ${SED} -e's/[[:space:]].*//'` ";\
        exec ${SU} root -c "$0 \"\$@\"" "$0" "$@"
fi

Those escapes, which appeared in pkg_tarup 1.6, used with the exec call seem to be the problem.  I don't know just what is being attempted there.  Whoever did it, please explain and hopefully fix it.
