Several varieties of partitioning programs have been adapted by Debian developers to work on various types of hard disks and computer architectures. Following is a list of the program(s) applicable for your architecture.
Recommended partitioning tool in Debian. This Swiss army knife can also resize partitions, create filesystems and assign them to the mountpoints.
A simple-to-use, full-screen disk partitioner for the rest of us.
Note that cfdisk doesn't understand FreeBSD partitions at all, and, again, device names may differ as a result.
Mac-aware version of fdisk.
One of these programs will be run by default when you select
tty2) by pressing Alt
and F2 keys together, and manually type in the
name of the program you want to use (and arguments, if any). Then
skip the step in
debian-installer and continue to the next step.
If you will be working with more than 20 partitions on your ide disk,
you will need to create devices for partitions 21 and beyond. The next
step of initializing the partition will fail unless a proper device is
present. As an example, here are commands you can use in
tty2 or under Execute A Shell to add a device
so the 21st partition can be initialized:
# cd /dev # mknod hda21 b 3 21 # chgrp disk hda21 # chmod 660 hda21
Booting into the new system will fail unless proper devices are present on the target system. After installing the kernel and modules, execute:
# cd /target/dev # mknod hda21 b 3 21 # chgrp disk hda21 # chmod 660 hda21
One key point when partitioning for Mac type disks is that the swap partition is identified by its name; it must be named “swap”. All Mac linux partitions are the same partition type, Apple_UNIX_SRV2. Please read the fine manual. We also suggest reading the mac-fdisk Tutorial, which includes steps you should take if you are sharing your disk with MacOS.
If you are installing onto a NewWorld PowerMac you must create a
special bootstrap partition to hold the boot loader. The size of this
partition must be 800KB and its partition type must be
Apple_Bootstrap. If the bootstrap partition is
not created with the Apple_Bootstrap type your
machine cannot be made bootable from the hard disk. This partition
can easily be created by creating a new partition in
partman and telling it to use it as a “NewWorld
boot partition”, or in mac-fdisk using the
The special partition type Apple_Bootstrap is required to prevent MacOS from mounting and damaging the bootstrap partition, as there are special modifications made to it in order for OpenFirmware to boot it automatically.
Note that the bootstrap partition is only meant to hold 3 very small
files: the yaboot binary, its configuration
yaboot.conf, and a first stage OpenFirmware
loader ofboot.b. It need not and must not be
mounted on your file system nor have kernels or anything else copied
to it. The ybin and mkofboot
utilities are used to manipulate this partition.
In order for OpenFirmware to automatically boot Debian GNU/Linux the bootstrap
partition should appear before other boot partitions on the disk,
especially MacOS boot partitions. The bootstrap partition should be
the first one you create. However, if you add a bootstrap partition
later, you can use mac-fdisk's
r command to reorder the partition map so the
bootstrap partition comes right after the map (which is always
partition 1). It's the logical map order, not the physical address
order, that counts.
Apple disks normally have several small driver partitions. If you intend to dual boot your machine with MacOSX, you should retain these partitions and a small HFS partition (800k is the minimum size). That is because MacOSX, on every boot, offers to initialize any disks which do not have active MacOS partitions and driver partitions.
