EESSI-extend doesn't load on systems which have LMOD_EXACT_MATCH=yes #746
Description
EESSI-extend just tries to load the default EasyBuild version. This doesn't work when a system requires LMOD_EXACT_MATCH=yes
{EESSI 2023.06} [casparl@tcn1 software-layer]$ module load EESSI-extend/2023.06-easybuild
-- Using /tmp/$USER as a temporary working directory for installations, you can override this by setting the environment variable WORKING_DIR and reloading the module (e.g., /dev/shm is a common option)
Configuring for use of EESSI_USER_INSTALL under /home/casparl/eessi
-- To create installations for EESSI, you _must_ have write permissions to /home/casparl/eessi/versions/2023.06/software/linux/x86_64/amd/zen2
-- You may wish to configure a sources directory for EasyBuild (for example, via setting the environment variable EASYBUILD_SOURCEPATH) to allow you to reuse existing sources for packages.
Lmod has detected the following error: These module(s) or extension(s) exist but cannot be loaded as requested: "EasyBuild"
Try: "module spider EasyBuild" to see how to load the module(s).
Executing this command requires loading "EasyBuild" which failed while processing the following module(s):
Module fullname Module Filename

EESSI-extend/2023.06-easybuild /cvmfs/software.eessi.io/versions/2023.06/software/linux/x86_64/amd/zen2/modules/all/EESSI-extend/2023.06-easybuild.lua
(we enforce this on our system since we got tired of people relying on defaults and then complaining that their code ran differently when we installed some new version - and they simply weren't aware :))
One option would be to have the EasyBuild version as a suffix - in which case there would be multiple EESSI-extend modules. Alternatively, maybe the module can still be convinced to load a default (can a module change lmod config on the fly...?) version. Or at least print a somewhat more clear error.
Note that as a workaroud, I load an EasyBuild module first, then load EESSI-extend. That way, it works
