I'm not sure if we even need typical boot scripts. Grub can be configured to use /tools/bin/init. /tools/bin/init can be modified to use /tools/etc/inittab.
/tools/bin/initscript adds /tools/bin to $PATH, if needed. /tools/etc/linuxrc (or whatever) can mount /proc, start udevd, sshd, and whatever else. Capabilities can also be set on agetty and login in this script. Agetty wants to write to /var/run/utmp and /var/log/wtmp. This can be modified to use /tools/var, but I don't know if that will cause problems. If agetty can use /tools/var, without causing problems with other stuff we install later, then we don't need to create directories before rebooting, and don't need root before rebooting (except for Grub). We create /tools/etc/passwd, and modify agetty/login, and maybe glibc, to use that. Same with /tools/etc/mtab. Or, would be be better to create directories, and set their ownership and permissions, before rebooting, and let agetty use /var, and let mount use /etc. Except for possible problems iwth utmp/wtmp, I like the first method better. Maybe there are other ways? robert
