The +partitions are numbered `1' through to `8' in +Linux and ``lettered'' `a' through to `h' in UNIX. +Linux kernels 2.2 and higher always correspond `1' to +`a', `2' to `b' and so on. For +example, <filename>rz0e</filename> in Tru64 UNIX would most likely be called +<filename>sda5</filename> in Linux. + +</para><para> + +Partitions in the disk label may overlap. Moreover, the `c' partition +is required to span the entire disk (thus overlapping all other +non-empty partitions). Under Linux this makes <filename>sda3</filename> +identical to <filename>sda</filename> (<filename>sdb3</filename> to <filename>sdb</filename>, if +present, and so on). Apart from satisfying this requirement, you +should carefully avoid creating overlapping partitions. + +</para><para> + +Another conventional requirement is for the `a' partition to start from +the beginning of the disk, so that it always includes the boot block +with the disk label. If you intend to boot Debian from that disk, you +need to size it at least 2MB to fit aboot and perhaps a kernel. + +</para><para> + +Note that these two partitions are only required for compatibility; +you must not put a file system onto them, or you'll destroy data. If +you're not going to share the disk with Tru64 Unix or one of the free +4.4BSD-Lite derived operating systems (FreeBSD, OpenBSD, or NetBSD), +you can ignore these requirements, and use the partitioning tool from +the Debian boot disks. See <xref linkend="partition-programs"/> for details. + +</para><para> + +Disks can be partitioned with the graphical disk configuration tool that +is accessible through the Application Manager, or with the command-line +<command>disklabel</command> utility. Partition type for the Linux file +system should be set to `resrvd8'. This can only be done via +<command>disklabel</command>; however, all other configuration can easily be +performed with the graphical tool. + +</para><para> + +It is possible, and indeed quite reasonable, to share a swap partition +between UNIX and Linux. In this case it will be needed to do a +<command>mkswap</command> on that partition every time the system is rebooted +from UNIX into Linux, as UNIX will damage the swap signature. You may +want to run <command>mkswap</command> from the Linux start-up scripts before +adding swap space with <command>swapon -a</command>. + +</para><para> + +If you want to mount UNIX partitions under Linux, note that Digital UNIX +can use two different file system types, UFS and AdvFS, of which Linux +only understands the former. + +</para> + </sect2> + + <sect2 arch="alpha"><title>Partitioning in Windows NT</title> + +<para> + +Windows NT uses the PC-style partition table. If you are manipulating +existing FAT or NTFS partitions, it is recommended that you use the +native Windows NT tools (or, more conveniently, you can also +repartition your disk from the AlphaBIOS setup menu). Otherwise, it +is not really necessary to partition from Windows; the Linux +partitioning tools will generally do a better job. Note that when you +run NT, the Disk Administrator may offer you to write a ``harmless +signature'' on non-Windows disks if you have any. <emphasis>Never</emphasis> let +it do that, as this signature will destroy the partition information. + +</para><para> + +If you plan to boot Linux from an ARC/AlphaBIOS/ARCSBIOS console, you +will need a (small) FAT partition for MILO. 5 Mb is quite +sufficient. If Windows NT is installed, its 6 Mb bootstrap partition +can be employed for this purpose. + +</para> + </sect2> |
