I would like to propose alernative option to add operations to be performed at system startup.
The idea is to have this controlled thru tce:s and requires no other actions than selecting the tce in question to be installed.
As an example if you would like to create different TC "flavors", each flavor could then be defined by the set of tce:s it includes.
A solution could be:
Place whatever scripts you want to execute during startup in the directory
/usr/local/bootlocal
inside your tce.
In /etc/init.d/tc-config you add, close to the invocation of /opt/bootlocal.sh, code that look what files (with x flag set) that exists in /usr/local/bootlocal and executes them.
