The main problem arises because we need to check if something is mounted a lot and /proc/mounts can be much larger than the mtab. The kernel update I mention above was needed for another reason but an operation to check mounted-ness was added at the same time to eliminate the need to look at the mtab. You might not need to go to a new kernel but I've only ported this particular patch as far back at 2.6.22 at this stage. I need to do a port back to 2.6.18 at some point soon so maybe that will cover most of the work needed for the in-between version as well. Anyway, it is still a big change so it really is your call as to whether it is worth the effort from yourselves, but this is the story, to the best of my knowledge anyway.
