Comment 5 for bug 1607920

I jointly worked with the zfsonlinux maintainer on a patch that will be merged in 0.7.0 milestone
https://github.com/zfsonlinux/zfs/milestone/11?closed=1

#4680, has been tackled in two parts. the first part (patch that will be merge in 0.7.0), change from /etc/mtab to /proc/self/mounts, and keep the existing mtab update functions alone in the mount helper.

Eventually, a second part would be for ZoL contributor/maintainers to do the integration with libmount. libmount didn't exist on Linux when the mount helper code was originally written. That could allow ZoL to drop their custom code.
