SystemImager 3.1.x and higher, has a new entry that is
recommended. From "man autoinstallscript.conf":
This section contains miscellaneous settings
used by BOEL (Brian's Own Embedded Linux), the embedded
linux that performs an install on autoinstall clients.
ˇ devstyle - Tells the autoinstallscript to
mount the devfs filesystem in the image prior to
running System Configurator, which prepares the
loader. Many boot loaders need to access the
disks at this point, and systems that use devfs won't
have any device files in the freshly copied image for
the boot loader to use (at this point, BOEL
has done a chroot into the root of the filesystem on
the freshly installed client.)
Feel free to ask if you have any quetions.
