thanks, SysV init script

[Sergio Ballestrero]

  Hello drinkers :-),

 as a newcomer to Arla, i am saying thanks to all the Arla developers, for
they helped me staying away from the always outdated Transarc client :-D

 Well, on a more practical side, i have attached a LinuxConf/RedHat
"compatible" or "enhanced" SysV init script, derived from the distribution
one. It has been simplified, because linuxconf takes care of at least some
of the checks. The ".init"  extension is gone, because so it has to be,
after the "enhanced SysV" specs. The comments at the start contain the
requested fields so that the handling by Linuxconf is mostly automatic -
i've chosen to use the same levels and priorities as the nfsd. It
is specific to my setup, using /opt/arla, but that should not be a
problem... 
 So, let me know if you like it. or not.
 
 Cheers,
   Sergio

PS the "enhanced SysV" documentation is available from
http://www.solucorp.qc.ca/linuxconf, in the technical section
