Probably Lachele has Amber installed on a non-compute server that
very few can access and that mounts the device on which Amber resides
as writable. This is the situation at OSC, and it does complicate testing
especially since Amber has become bloated. Alternatively others have
different but related issues: Amber contains a testing
suite that is soo long it overruns an interactive cpu time limit
and a suite that requires a variety of parallel footprints, which may
only be available from a batch job, for thorough testing.
The simple solution for these situations is to tar the Amber tree,
untar it on local scratch disk, and test it there from a batch job:
Here is one from Amber 8; it will need updating for Amber 10.
