Thanks for your answer.

I know about provmethod. But it seems to me that it doesn't provide a
way to instruct xcat to perform *serveral* actions (bmcsetup, then
runimage, then boot osimage) at deploy time as a tabedit of chain can
with an entry like :
"compute",,,"runcmd=bmcsetup,osimage=centos6.7-x86_64-netboot-compute",,,
Am I missing something ?

I guess those are the postinstall scripts you mention later in your
message. But I don't see any reference to postinstall scripts in a
stateless setup : is that a statefull or statelite feature only ? I've
read only about postscript and postbootscripts.

I thought rpm's were installed inside the image with a yum command
(installing inside the chroot) via the /install/postscripts/ospkgs
postscript.
That would make sense but then why wouldn't *every* postscripts
(associated with the osimage object) be run in a similar manner by
genimage ?
This would, for some, make less sense to me, thus my confusion.
Thanks
