/etc/init.d available in all Linux distributions?

Hi All,

I would just like to know if the /etc/init.d directory which is used to hold the start up scripts is available in all linux distributions? Are there any exceptions

One more question

Is the command chkconfig available in all Linux distributions and used in a similar fashions across all Linux distribuitions?

Thanks in advance for your answers.....

Cheers

/etc/init.d is available on most Linux distributions that I know, except for Gentoo, which uses /etc/rc.d/init.d

I have yet to see chkconfig in SuSE, Debian (and -based), and Gentoo, they all have their own tools for administrating run-level services.

Arch Linux (i.a.)
