be very careful with this application.
I corrupted a whole server, unrecoverable, by clicking submit on the 'Installed' tab.
I updated with YUM fine to start, everything went well, except ssh would not come up, even after a reboot.
I went into the web interface, clicked on the installed tab, selected openssh to view details, and clicked submit. Next thing I know the whole server packed up and died.
Examining it as much as we could, even cp and mkdir no longer worked, so something drastic was done from this page by the selection .. it's not clear what the actions do. I assumed I could view details of the chosen application, apparently not! :\
maybe a little on-screen documentation?
