[expert] 7.0 network upgrade fails

[Concis]

Hi all.

I have a strange error message that I would be grateful if someone could
shed some light on.

I have a Laptop and I am installing Air(7.0) with a bootdisk generated from
network.img.

Everything works out alright until I am to select which packages I am going
to install. I get this errormessage: "An error occured: all: canīt open dir
/tmp/rhimage/Mandrake/RPMS No such file or directory"

It seems to me that maybe the bootdisk is flawed?

I selected Customized and then Development as options for the install.

Kind Regards,
Fredrik Hult
