Pkg xen devel - Jul 2008 - Bug in xen-utils-unstable

Hello there,

I might have found some bug in xen-utils-unstable (amd64). 

When starting some Linux in domU, the ?ramdisk? parameter of my .cfg file is
overridden and has the same value as the ?image? parameter.
That ends in an unbootable VM (vmlinuz is not a ramdisk ?)

?No filesystem could mount root, tried: cramfs
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(x,y)?

[.cfg file]
ramdisk     = '/boot/initrd.img-2.6.18-6-xen-amd64'
kernel      = '/boot/vmlinuz-2.6.18-6-xen-amd64'
...

Some field must be badly passed to some function somewhere. I?m not used to
python

Best :)
