Quote the context you need so your question makes sense and reply below it, and you're more likely to get useful answers as it'll be less work to reply properly. Here's how it should have looked, now quoted another level for my reply: >> That said, there's been a lot of work recently on getting >> swap-over-NFS to work properly -- effectively giving a new interface >> for the swap code that doesn't rely on direct mapping to device >> blocks.

The answer is yes, I've definitely seen commit comments about swap over NFS on recent commits, so the work is indeed going in, tho it may well still be a WIP. (I don't use NFS here and in fact with 8-16 gigs RAM common these days, I don't use swap so much any more either and often don't even have the kernel swap option on for my current configs unless I'm using it for suspend-to-disk, so I've not followed the issue closely enough to know current in-kernel status, but based on the commits I've happened across, yes, the work is certainly going in, if the feature isn't already there and working in general and they're simply tweaking it now.) -- Duncan - List replies preferred.
