However… if I add to the host’s config a DISK IGNORE /, then while
the text (as above) only shows /tmp, I lose /tmp’s graph line and it

and after a line for /tmp, with no effect. As soon as I add the
IGNORE line, /tmp’s graph line vanishes on next update.
Try this:
HOST=foo
DISK %^/$ IGNORE
so you use a regex pattern that only matches "/" to ignore that
filesystem.
I was expecting this to work - but now I have
Filesystem 1024-blocks Used Available Capacity Mounted on
none 131072 15456 115616 12% /tmp
and below it, / is graphed. The graph line for /tmp vanished. I'm very
confused.
Hmm, yes - that can happen because you now have two RRD graph files, but
only one graph showing up on the webpage. You should have both of them
on the graph in the "trends" column, though.
Either wait 48 hours - then the root-filesystem graph will go "stale" and
automatically be ignored on the "disk" status graph display. Or you can go
to the ~hobbit/data/rrd/HOSTNAME/ directory and delete/rename the
"disk,root.rrd" file out of the way.
