his doesn't matter, but if the directory has been specifically deleted ahead of time so that it is created afresh, this is an unnecessary window. We can avoid this by passing the caller-provided BITS to 'mkdirat' when attempting to create the last directory. * gnu/build/activation.scm (mkdir-p/perms): Create target directory with BITS permissions.
