[ydl-gen] Upgrading YDL on PS3 cluster

[Sylvain HENRY]

Hi,

I'm in internship in a company which has bought a cluster (composed of
8 PS3 nodes and a
G5 head all running YDL 6.0) to Terrasoft a few months ago.

I would like to upgrade YDL to YDL 6.1 on PS3 nodes. I used:
 yum --installroot=/var/lib/yhpc/images/myimage update
and it worked. But when I reload the image and reboot, the old Linux
kernel (2.6.22) is
still used.

Does anyone know how to switch to the newly installed kernel (the one
in /boot/)?

Thanks!
Sylvain
