[ANNOUNCE] Update of the MondoRescue server

Update of the MondoRescue server

In order to prepare the delivery of MOndoRescue 3.3.0 later this week (more on
that later !), I'll update the MondoRescue server to the latest Mageia 7 that I
have tested successfully on other machines.

So the server will be unavailable starting Wednesday the 20th of november at
9:30AM CET till 11:30AM CET (that shouldn't take longer, but I need to check
the various services, svn, http, ftp, trac, mail, sympa, ...)
