when using chroot, I found that sort, and add_drv can't be used in chroot.
bash-3.00# chroot /secroot /usr/sbin/add_drv
/usr/sbin/add_drv: getexecname() failed
bash-3.00# chroot /secroot /usr/bin/sort
/usr/bin/sort: getexecname() failed
following is the turss message. what is the reason. could someone help me.
bash-3.00# truss chroot /secroot /usr/bin/sort
