Created attachment 360826 [details, diff] nilfs-utils-2.1.5-r1.ebuild.patch I found that nilfs_cleanerd is not started in case /etc/mtab is a symlink. To fix this issue upstream suggests [1] to use libmount and really after I've enabled it everything works as expected. Please, apply patch in attachment.

I've modified the ebuild to build against libmount. Thanks.
