ABOOT.CONF(5)

NAME
aboot.conf - The configuration file for aboot(8)

DESCRIPTION

aboot.conf contains a list of boot settings for aboot(8). Each boot setting has a unique number which can be supplied at the SRM-Prompt.

aboot.conf must be in a directory called etc on the same partition as your kernels reside on unless you explicitly list the partitions for your kernels (see below for details). So if you create a separate boot partition (called /boot) then aboot.conf should reside in /boot/etc/.

In the following example the kernels reside on a different partition (hda4) then / belongs to (hda5) while in the fourth line /boot is on the same partition (hda6) as /. Therefore aboot.conf can be located on any of the three partitions but always in a directory etc at the top level of the file system on that partition. You can change the partition to use with abootconf(8).

  EXAMPLE ABOOT.CONF

    0:4/vmlinuz root=/dev/hda5
    1:4/vmlinuz root=/dev/hda5 single
    2:4/vmlinuz.old ro root=/dev/hda5
    3:4/vmlinuz-2.4.9-32 root=/dev/sdc3 initrd=/initrd-2.4.9-32.img console=tty0
    8:6/boot/vmlinuz ro root=/dev/hda6

The first number is a unique identifier for each boot configuration. To boot a certain configuration at the SRM-Prompt you would issue

boot dka0 -fl "0"

where dka0 has to be replaced by your boot device and the boot configuration (0 in this case) can be replaced by any defined in etc/aboot.conf.

After the colon the number of the partition the kernel resides on is given. 1 corresponds to the BSD partition labeled A:, 2 to B: and so on.

After the slash the name of the kernel to boot is given, including a possible path. If your kernel does not reside on a file system but is located directly after aboot at the beginning of the hard disk you would omit the number, the slash and the kernel name.

Next the name of the partition to mount as / is given. Other kernel parameters follow as required. As shown also an initrd can be specified.

The contents of this file can be shown before booting if necessary by using the interactive mode of aboot(8) (booting with the flag "i") and then issuing "h" at the aboot-prompt.
