  Currently there are three different init scripts inside the SCST project:
  scst, iscsi-scst and qla2x00t. This makes it unnecessary hard for users to
  run several target drivers simultaneously. Additionally, several variants of
  these init scripts exist for different distributions. This patch unifies all
  these init scripts into a single init script. Additionally, some new features
  have been added:
  - Kernel module parameters can now be specified per kernel module in
    /etc/default/scst. An example:
   ib_srpt_parameters="thread=1 srp_max_req_size=4200"
  - When using the sysfs interface, compute the kernel module list from scst.conf.
    Or, editing the SCST_MODULES variable is no longer necessary.
  - When using the procfs interface, the SCST handler kernel module list is
    computed from /etc/scst.conf. The list of target driver kernel modules must
    now be configured in /etc/default/scst.

  Other changes:
  - scstadmin output is shown if scstadmin fails.
  - Running make -C scstadmin install does no longer cause the scst script to
    be started at the next reboot - it is better to leave this as an explicit step.
  - Made the error message generated if the lsb-core package has not yet been
    installed more clear.
  - Use proper init script path on Slackware.
  - make uninstall: run remove_initd under chroot if $(DESTDIR) is not empty.
  - Fixed a bug in "make -C scstadmin uninstall": the path specified for removing
    /etc/init.d/scst was wrong.
  - The command /etc/init.d/scst restart will only try to start SCST if stopping
    succeeded.
  - Replaced "mkdir -m 755 -p $(DESTDIR)$(INITDIR)" by
    "install -d $(DESTDIR)$(INITDIR)" because of uniformity.

  These changes have been tested on Ubuntu 11.04, Fedora 15, CentOS 5.6,
  Scientific Linux 6.0, openSUSE 11.4, SLES11 SP1 and Slackware 13.37.

  More /ec/init.d/scst tuning:
  - Works now if the SCST modules have been compiled into the kernel (=Y) instead of being compiled as modules (=M).
  - Rename DAEMONS into SCST_DAEMONS.
  - Use the same name for loading and removing the iSCSI kernel module (iscsi_scst).
  - Set the path after having read /lib/lsb/init-functions instead of before.
  - Remove the path from the killall command.
  - When parsing /etc/default/scst, handle both parameters with and without embedded spaces correctly.
