Closed devimc closed 5 years ago

devimc commented 5 years ago

Other cloud-config implementations like cloud-init resizes automatically the rootfs to the maximum allowed, ucd should do the same.

fixes #34

@mdreyesm please do me a favour and test it in your baremetal machine :smile:

ahkok commented 5 years ago

Yeah, alright, I can see this is the way to go.... Now we need testing.

mdreyesm commented 5 years ago

I already tested the change deploying a Clear Linux image with the new binaries using Ironic in baremetal hosts, and it seems to work.

Thank you very much @devimc
