Background
Smaller, tangible activities to be implemented under the EOSC-Nordic umbrella, in support of the NLPL virtual laboratory.
User Management
The project maintains an email list for all users with access to the NLPL virtual laboratory. We need to extract programmatically, on Saga and Puhti, which users are associated with any of the NLPL billing project(s), which should be read from a local file. This mechanism should be run as cron(8) job every night and rewrite another local file with active email addresses (which is then used at NLPL headquarters to automatically update the set of mailing list subscribers).
File System Management
With multiple users maintaining a shared collection of directories and files (aka the community directory, the shared software and data installations that make up the core of the virtual laboratory), we frequently run into permission challenges that at times are tedious to resolve or require administrator priviliges (which the NLPL developers cannot have). We would like to see an interface where a cron(8) job regularly reads a specification of permissions and such from a file (maintained by NLPL), quality-controls the contents, and then executes corresponding actions, e.g. something like
software/modules/etc/nlpl/foobar rm software/modules/ chgrp -R nlpl software/modules/ chmod g+rwX,o+rX
