We have enabled a service called superchown. This service allows you as a volume owner to change the ownership of files in the volume. Normally you need mailto:postmaster@science.ru.nl’s help to make these changes, but with superchown you can do it yourself.
Currently this is implemented as a command line utility that is available on the LILOs. Its manual page has all the details:
man superchown
If you have further questions, or want to use superchown, please reach out to mailto:postmaster@science.ru.nl.
