p_l in #zfsonlinux reported that he had issues mounting filesystems that were resolved by adding rc_need="mtab" to /etc/init.d/zfs. Closer inspection revealed that we do have a race, but it is not clear how this race caused mounting to fail. What is clear is that this race should be fixed, so lets add the proper `use mtab` line to handle it. Signed-off-by: Richard Yao <ryao@gentoo.org> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #2148
