That sounds like a good compromise to me! Another thing to consider: /etc/init.d/localmount should check whats already mounted and leave that out. But it will act as fallback if the minimal initramfs fails to mount /usr or /var for any reason. That way anybody migrating to that "minitramfs" will not risc an unbootable system. -Marc -- 8AAC 5F46 83B4 DB70 8317 3723 296C 6CCA 35A6 4134
