ouch! Yes, such polling systems are quite standard and a must
for reliable server maintenance. Of course they will not be
100% fool proof either.

However, having easy access to a spare machine which has the OS
pre-installed and on which you can restore the full the
wiki-backup, maybe something to look at.

Indeed! I hope you weren't stressed unnecessarily by my e-mail,
and I hope this is now just clear to the audience:
In case of severe problems with the R-Wiki do contact Philippe
Grosjean by "personal" e-mail (i.e. not just assuming he reads
