Every distribution has slightly different requirements for their init scripts. Because of this the zfs package contains several init scripts for various distributions. These scripts have been contributed by, and are supported by, the larger zfs community. Init scripts for Gentoo/Lunar/Redhat have been contributed by: Gentoo - devsk <devsku@gmail.com> Lunar - Jean-Michel Bruenn <jean.bruenn@ip-minds.de> Redhat - Fajar A. Nugraha <list@fajar.net>
