Hello; I found that writing to overlayfs mount may be denied to a process with own user namespace and uid=0 inside that namespace, unless I explicitly chown lower-work/work directory to a parent namespace uid corresponding to that user namespace uid 0. The test case might be found at https://unix.stackexchange.com/questions/229782/overlayfs-doesnt-work-with-unprivileged-user-namespace Tried with debian's 4.1.6 and 4.2-trunk. Could someone please clarify if this is a bug or a feature, and if this might be changed in future? Thank you!
