Hi, I'm just trying a bit around, and then came over the following issue: When I mount a file system directly via mount_union(8), I have no problems with handling the file system (everything works as expected). But when I mount a file system directly with the option `-o union`, and the underlying filesystem is read-only, I will always get EROFS when I'm not at the top directory. E.g. when / is still mounted read-only, and you try mount -t tmpfs -o union tmpfs / Then you'll be allowed to do anything in /, but nothing in any of the descendants, e.g. you cannot touch /var/file. Why is it like that? Is there any way to circumvent that (mount_union(8) is no option for me)? Regards, Julian
