I compiled  xen-4.0.0 like this :


make -j2 world KERNELS="linux-2.6-xen0 linux-2.6-xenU" 2> ../FILE

----------------- FILE ------------------------
the program '/bin/bash' called '/usr/bin/udevinfo', it should use 'udevadm info <options>', this will stop working in a future release
select-repository: Searching `.:..' for linux-2.6.18-xen.hg
select-repository: Ignoring `.'
select-repository: Found ../linux-2.6.18-xen.hg
/bin/sh: line 2: [: argument expected
select-linux-arch: i386


What is linux-2.6.18-xen.hg ( taken from hg clone http://xenbits.xensource.com/linux-2.6.18-xen.hg )
and why it is required by xen-4.0.0 for compilation ?
