Hello @GeorgeGayno-NOAA I have included updates for building ufs-utils in a container provided by @mark-a-potts. This is work being coordinated with @aerorahul (@WalterKolczynski-NOAA added since Rahul is on leave) and references NOAA-EMC/global-workflow Issue #3025.
For links to the fix directories, we don't want to have the fix directories in the container so did not update link_fixdirs.sh.
Please let me know if including the container build is okay, and if so, how we should handle link_fixdirs.sh. Maybe a warning message?
Thanks!

@GeorgeGayno-NOAA Sorry about that! Code is finalized and is consistent with other global-workflow submodules. Thanks.
