start a program at boot, before any other service

[antolap]

If I want to start a program at boot time, before any service are started, in which file I should put it?

rc.local is started at the end, which is started as first ?

rcorder(8) is your friend here:

rcorder /etc/rc.d/* /usr/local/etc/rc.d/*

prints the order the rc scripts will be run in.

and what should I put in the my custom rc file to ensure that it will be the first in the list of rcorder ?

# PROVIDE: xx
# REQUIRE: xx
# KEYWORD: xx

only these lines influence boot order?
what to write, to be the first to run?

Tomorrow I'll study manual pages

See also service -e — prints enabled rc scripts in order.

And you’ll likely want something like


# AFTER: FILESYSTEMS
# BEFORE: NETWORKING

... before any service are started, ...

Serious? Before file systems are mounted, before sysctl is configured, before networking is up? I doubt it.

It might help if you could explain what you are trying to accomplish.

Ok solved

How?

putting:

# BEFORE hostid

in /etc/rc.d/myfile

I don't know if there's an absolute solution

Hacking /etc/rc is the only way to be absolutely sure. Look for both calls to rcorder, after that insert your script in the start of the list. Then nothing can override your script and your script totally ignores the positioning directives.
