I sort of understand this need, but I suggest that it's caused by poor
namespace management, and that the solution should be to improve that
rather than try to keep your RWs and ROs out of sync with each other.
There are several ways to have versionized trees: two are
- at the top (ie, different root volumes)
- in the middle of the filesystem space via symlinks (eg, have a
volume 'in the middle' of your hierarchy that lets you have 'dev' and
'prod' links) -- take a look at slides 15 & 16 of
for one way to do that
