Both answers point to the same issue. 'ifclass' is a bash function / 
subroutine. If one uses a different interpreter then bash, one will not be 
able to use any of the fai-specific functions.

Hooks are automatically parsed in a bash context, scripts use whatever 
interpreter you choose.

'/bin/sh' is likely to be provided by dash on recent debian releases and 
bash on older ones, but it ~could~ be something completely different. It's 
been a long time since I saw a system which provided /bin/sh by an actual 
'Bourne shell'.
