I would prefer to use 1 method for all / replacements, as it helps
with processing the rrd files lateron. (in graph generation)

Personally, I prefer not to use them, but on the previous job they used them
very often, as a space is an invalid character.
There I started to use the double underscore as replacement for the slash,
after a short period of using root for / and var, home etc. etc. for the rest
of the filesystems. A uniform replacement of the / had proven to be more
practical then the old naming convention. To be honest, I didn't switch to
the double underscore due to finding some in directory names, but because
I was using mrtg that time and it crashed on a filename with only 1 _ (yep
I currently have a shell/perl script for the df monitor. When it helps a bit,
I could send it. (or even post it here, as it's not that big)
