[Planetlab-devel] Minimum disk size per MyPLC node

[Brett Lane]

  Thanks for the insight. Indeed, the method I used was adding /minhw to 
the end of the Model field.

Hardcoding that constant and running the bootmanager seemed to do the 
trick, thank you. However, though I'm pretty sure this error is 
unrelated, I want to be complete in making sure:

Exception while running: Running chroot /tmp/mnt/sysimg  rpm --import 
/etc/pki/rpm-gpg/RPM-GPG-KEY-planetlab failed (
rc=1)

I guess my keys are messed up.

Thanks again,
Brett

IIRC we came across somebody with a 16 Gb memory stick (yeah...) and made this change in a rush...
