Looks good so far, except that I'm not sure whether it makes sense to 
run 'O'ffline tests 4 times a day. You may want to add '-l selfteststs' 
and '-l offlinests' to see self-test activity and duration in the syslog.

Note that you could test the effect of '-s REGEX' by running 'smartd -q 
showtests'.

DEFAULT as device name could be used for common settings, for example:

DEFAULT -H -l selftest -l error -m [email protected]
/dev/twa0 -d sat+megaraid,4 -s 
(O/../.././(00|06|12|18)|S/../.././01|L../../5/01)
/dev/twa0 -d sat+megaraid,5 -s 
(O/../.././(00|06|12|18)|S/../.././01|L../../5/02)
/dev/twa0 -d sat+megaraid,6 -s 
(O/../.././(00|06|12|18)|S/../.././01|L../../5/03)
/dev/twa0 -d sat+megaraid,7 -s 
(O/../.././(00|06|12|18)|S/../.././01|L../../5/04)

This also eases the temporary addition of directives like '-M test' to 
all devices.

Christian
