elchildo wroteI tried partitioning manually and didn't work for me either.
The simplest workaround I found is to install normally, when the installer fails at the root password setting, go edit /usr/lib/obarun/install/config.sh, at the end of the file comment or delete the "|| die..." part like this:
printf "%b\n" "${pass}\n${pass1}" | passwd -R "${NEWROOT}" "${user}" # || die "unable to set the ${user} password" "clean_install"
...then run the installer again and it will let you continue with the installation. As setting the passwords won't work anyway, when the installation finishes and before rebooting set them manually (sudo su -, chroot /mnt and passwd).
i could be wrong, but i use a similar method to set the password to the new user on my own unattended script, that extra
"%b\n" at the beginning might be piping an extra new-line to passwd. and %b? that is an oblog syntax i believed.
UPDATE: ok, false assumption above. here's my test
is
passwd -R bugged? this is basically the error is used as such
ob66# passwd -R /mnt root
passwd: Module is unknown
passwd: password unchanged
ob66#
in anycase chpasswd should also work:
ob66#
ob66# echo "root:password" | chpasswd -R /mnt
ob66#
