[CentOS] Dell unofficial community repository - what do you think?

Hi all.

I am currently gathering information about firmware update on Dell
PowerEdge machines.
I've found
http://linux.dell.com/wiki/index.php/Firmware-tools_announcement
and
https://linux.dell.com/repo/community/
It is an unofficial, community supported repository.

What are your experiences: should I perform firmware updates the
traditional way by downloading *.bin packages from Dell and run them
manually or should I use this repo? Is this repo "safe" and releases
stable packages?

Best regards,
Rafal Radecki.
