[debian-knoppix] [script] Samba start script

[Chris Liechti <cliechti@gmx.net>]

the script "sambastart" is like "sshstart" starting a service and could 
therefore go to the same KNOPPIX submenu ;-)
this can be handy in a Windows environment where one uses Knoppix as 
rescue disk. and as nmbd is started it makes it also easy to lookup the
Knoppix machine if one does not know its IP number. (hint: "nmblookup 
Knoppix" on linux)

it updates the samba config files and exports the knoppix users home 
directory (read/write) and it asks if all the partitions under /mnt 
should be exported too. if this is done, it adds the corresponding 
entries to smb.conf, including automatic mount if the share is accessed.
(mounts are r/w as /bin/mount is used with the fstab entry)

that this can work it must have a valid samba password set. the script 
"knoppix-setpassword" takes care of that (it is automaticaly called 
within sambastart). i'd recomend to use that in "sshstart" too as it 
uses a nice (X)dialog interface ;-)

knoppix-setpassword should be installed in /usr/bin or /use/local/bin so 
that it is found by the sambastart script. (sorry cant provide a ready 
made deb)
