Q1: usr/src/cmd/distro_const/slim_cd/slimcd_generic_live.xml Why the change from network/routing/ndp -> network/sendmail-client I don't understand the connection this has to bug 6440. Q2: How will the "module" line, in the GRUB entries on the LiveMedia, find the correct boot_archive? Currently it is: module /boot/boot_archive I don't understand. Please explain. Thanks. Joe
