Re: FW: using OCAML xenstored

[Alex Zeffertt <alex.zeffertt@eu.citrix.com>]

Some time ago I sent some patches against xen-ocaml-tools.hg to make it work as 
replacement for the C xenstored in xen-unstable.hg.  One of the patches was to 
fix this install path issue:

http://lists.xensource.com/archives/html/xen-devel/2009-04/msg00697.html

I don't think these patches were applied. (I don't know if there is a reason for 
this.)  It might be worth checking out the whole patch queue if you are 
intending to use it with xen-unstable.hg.

Regards,

Alex
