I had a long twitter thread about this with some BSD developers, https://twitter.com/landley/status/1127148250430152704 asked on the toybox list for opinions, http://lists.landley.net/pipermail/toybox-landley.net/2019-May/010461.html and became aware of this patch set when the android bionic maintainer pointed me at news coverage of it http://lists.landley.net/pipermail/toybox-landley.net/2019-June/010536.html So there would appear to at least be interest in the concept. (The conclusion I came to looking at it last month is is it can't be done without kernel support, but if such support _does_ arrive I want to add it to toybox.) Rob
