@DavidHuber-NOAA Do you have a chance to review this PR?

Confirmed the new spack-stack location is correct. Thanks!

@RussTreadon-NOAA @ShunLiu-NOAA Can we go ahead and merge this unless there are any more approvals needed?

[RussTreadon-NOAA]

@ShunLiu-NOAA asked Ming, Cory, and I if ctests need to be run for the PR on WCOSS2, hera, orion, or hercules. We agreed that confirmation that the changes work on Jet is sufficient.

I should merge this yesterday after approval from Russ, Cory and Ming.
