Highlighting this and the BUGS section makes more sense. While accurate, the combined terminology of mount points, filesystems, local, and remote was terse enough to confuse me. I may experiment more to definitively reproduce my permissions issue. >> Will experiment with read-only and lndir(1) in the coming week. > > iirc there's something in the source tree which doesn't work with > a read-only mount (xenocara is OK though), not sure whether lndir > gets around that or not. > I'm slowly whittling down the options required. Building the kernel creates and populates a compile directory, while userland wants to create obj symlinks and has problems with binutils/gdb when using noexec. Haven't gotten to lndir yet.
