Comment 92 for bug 2046844

@arraybolt3: Answer to your question. bwrap requires capabilities within the user namespace. unshare is a little more forgiving in that what it requires depends on the options passed but most of the options also require capabilities within the user namespace.

The potential solution I mention is comment #91 is to define a profile for bwrap that allows it capabilities within the namespace but does not allow its children capabilities within the namespace, so that bwrap and unshare can not just launch an application to by-pass the restriction. This seems to work well for unshare but there are cases where bwrap is failing in unexpected ways (which is still being debugged).

At this late stage the plan is to try to get a fix for bwrap in but if necessary to file an SRU if necessary for the bwrap fix. So yes this is being worked on and even if the fix isn't present on day one we do plan to get it fixed.
