Launching rose-stem with cylc vip ... -S USE_MIRRORS=true ... ./rose-stem now broken on the MO hpc?

[MichaelWhitall]

Hi folks,

I think a recent change on the Met Office hpc has banned use of the -S directive when submitting jobs to the hpc; see:
https://engage.cloud.microsoft/main/org/metoffice.gov.uk/groups/eyJfdHlwZSI6Ikdyb3VwIiwiaWQiOiIxNTk2MTgzODM4NzIifQ/new

As it stands, the Simulations Systems working practices recommend using a -S directive when launching rose-stem tests for lfric_apps, UM, etc:
https://metoffice.github.io/simulation-systems/Development/testing.html

I can confirm that my latest attempt to launch a UM rose-stem test suite using the recommended command now fails:

cylc vip -z group=developer -S USE_MIRRORS=true -n my_rose_stem_suite ./rose-stem

The rose-stem remote_init_ex1a task on the hpc submit-fails, as expected given the change they've made to the hpc, because of the -S USE_MIRRORS=true which we're supposed to add to tell rose-stem to extract from the local git mirrors (recommended practice).

Can anyone suggest how we should launch rose-stem now? Can we just ditch the -S USE_MIRRORS=true?

Cheers!
Mike

OK it looks like the problem isn't the -S USE_MIRRORS=true in the command to launch rose-stem from VDI (I tried leaving that out and it still submit-fails). For UM rose-stem, the problem is there's a

        [[[directives]]]
            -S = /bin/bash

in the file:

rose-stem/site/meto/family-ex1a.cylc

Deleting that directive from the UM rose-stem site file makes the problem go away :)

I haven't checked yet whether other repo's rose-stem suites have a similar problem...
