We would be most happy to accept any patch you care to submit.

I would only ask you to maybe share your thoughts with us during the design
phase so that we can help you to write your feature most fitting to the general
ReaR design philosophy. If you don't want them public on the list, just mail us

Some thoughts:
- ATM ISO creation happens after the backup which would conflict with writing
the ISO at the beginning of the tape. I don't recall any reason why we could not
switch the backup phase and the output phase (well, maybe some very small
reasons) in general to make it easier for you. If you change this please take
care of handling the RESULT_FILES properly, e.g. adding it to the TSM backup.
- If you want to move around a lot of things please submit that as several
patches (e.g. one for moving everything around without changing much code and
another one for the new code). This would help us to do the code review because
we need to mirror your changes with the proper svn move commands to keep the
version history. As an alternative you could also send me your modified working
copy, I review it and simply commit it. Thus you could do the svn move business
- ATM we have no case where OUTPUT and BACKUP is the same and I would like to
see some discussion on this list about how to best cut the features. Maybe have
OUTPUT=TAPE and BACKUP=TAPE or maybe BACKUP=NETFS and NETFS_URL=tape:///dev/nst0
and then OUTPUT=TAPE with some magic to set TAPE_DEVICE from NETFS_URL ... The
idea would be to maximze the code reusage from NETFS which does already a fine
job of tar backups... I would not mind renaming NETFS to BUILTIN to make it
clear that this is the built-in backup method...

Kind Regards,
