This might seems trivial to many people. However, I don't really know how to have some of my SysV init scripts being executed every time a machine restart. For Fedora, this is very simple using
chkconfig. However, I don't know what is its equivalence on Ubuntu.
Googling around and I found that the command is actually
update-rc.d. A default modus operandi is
update-rc.d foobar defaults
where foobar is my init script. This will place links to
/etc/init.d/foobar on appropriate run levels.
