Description of problem:

When creating several partitions using interactive partition editor of the
installer, user doesn't have any control over the order in which  partitions are
really created in. It seems the tool sorts newly created partitions by size,
and then allocate them in partition table. This way the biggest partition gets
smaller partition
index. E.g. swap partitions are not the largest ones, that means that swap
partitions move to the end of the disk, where IO is much slower than at the
begining.. So user has NO way to place swap partition at the begining of the
harddisk, except by NOT using that interactive partition editor.
Comment 1 Jeremy Katz 2003-02-10 13:12:54 EST
This is intentional as its the only way we can make sure there is space
remaining to add the partitions which are larger and potentially growing.  If
you mark a partition as "must be primary", then that gives it additional
priority and it will get allocated before partitions which don't have primary
specified
Comment 2 hvv 2003-02-11 05:06:30 EST
Utilizing primary partitions is totally wrong for this.
Also precise control over the order of partitions should be available
at least in the Expert mode, and better yet - it there should be
a checkbox somewhere in DiskDruid to control the automatic reordering
of partitions.

You can also create partitions by specifying the cylinder range.  Double click
on a free space region and you can do this.
