[Xen-users] xen-create-image puts "swap" before "root"

[Alexandre Kouznetsov <alk@xxxxxxxxxx>]

Hello.

I'm setting up a Xen hypervisor on a Debian Wheezy, and facing a issue I 
wanted to deal with since a long time ago.
It's about the order in which xen-create-image handles DomU's disks.  By 
design of /usr/bin/xen-create-image perl script, the "swap" partition 
always goes in the first place on the list, followed by "/" and then the 
rest of them.
Between other things, this setup makes it tricky for PyGrub, there has 
to be specific code in xm.tmpl to make the "/" to appear in the first place.
I'm wondering why is it so. I would expect the "/" to go first, followed 
by swap and then the rest of them. Even better, if a partition schema 
from /etc/xen-tools/partitions.d is used, why not to use the disks in 
the same order as they appear in the partitions file, for sake of 
predictability.
This is not feature request. There must be a reason to handle the 
partitions in this order. I'm very curious to know which is it, before 
proposing any change.
Greetings.
