d	delete partition
a	create partition
w	write partition table
q	quit
cr	cartridge return or press enter

Part 2: Partition Table

Partitions	Details	File size	Comment

a b	swap	300m	x2 of physical memory
a c	physical drive		cannot be deleted
a d	/tmp	100m
a e	/var	10g	larger for log files storage
a f	floppy		reserved for floppy drive

a i	/var/qmail/queue	500m	reserved for qmail installation
a j	/var/noneqmail/queue	500m	reserved for qmail installation
a k	/home	*	rest of the unused disk space

Part 3: Installation

After setting the partition tables

w (cr)
q (cr)

This are some of the messages displayed:

No label changes.

The root filesystem will be mounted on wd0a.

wd0b will be used for swap space.
Mount point for wd0d (size = 102312k) (or one or one [/tmp] (cr)
Mount point for wd0e (size = 10485720k) (or one or one [/var] (cr)
Mount point for wd0g (size = 3145968k) (or one or one [/usr] (cr)
Mount point for wd0h (size = 24832048k) (or one or one [/home] (cr)
Mount point for wd0d (size = 102312k) (or one or one [/tmp] done (cr)

Done no available disks found.

You have configured the following partitions and mount points:

wd0a /
wd0d /tmp
wd0e /var
wd0g /usr
wd0h /home

The next step creates a filesystem in each partition, ERASING existing data.

Are you really sure that you’re ready to proceed? [n] y (cr)
