This commit replaces the zfs.redhat.in init script with a slightly modified version of the existing zfs.lsb.in init script. This was done to minimize the functional differences between platforms. The lsb version of the script was choosen because it's heavily tested and provides the most functionality. Changes made for RHEL systems: * Configuration: /etc/default/zfs -> /etc/sysconfig/zfs * LSB functions: /lib/lsb/init-functions -> /etc/rc.d/init.d/functions * Logging: log_begin_msg/log_end_msg -> action Features in LSB which are now in RHEL: * USE_DISK_BY_ID=0 - Use the by-id names * VERBOSE_MOUNT=0 - Verbose mounts by default * DO_OVERLAY_MOUNTS=0 - Overlay mounts by default * MOUNT_EXTRA_OPTIONS=0 - Generic extra options Existing RHEL features which were removed: * Automatically mounting FSs on ZVOLs listed in /etc/fstab Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Issue #3153

# description: This script will mount/umount the zfs filesystems during

# should be mounted is handled by the zfs 'mountpoint' and
|
|
# 'canmount' properties. See the zfs(8) man page for details.

# It is also responsible for all userspace zfs services.
