Dynamic or static partitions

There are two forms of disk directives, those that dynamically create disk partitions each time at boot time, and those that create permanent locally deployed portions of the master image.

The DISKMOUNT and DISKSWAP directives cause the specified disk(s) to be re-partitioned (if necessary) and filesystems to be created every time at boot time. These directives are best used for creating filesystems for temporary storage, such as /tmp.

Note: Local disk partitions that need to retain data across a reboot should be handled normally with /etc/fstab.
