I want to execute the following commands when my laptop is booted -

cp /etc/alsamix.conf /etc/asound.state
/sbin/alsactl restore 0
chmod 666 /dev/snd/*

Obviously it is essential that these are executed after the files in /dev/snd are created at boot time. I have been told to put these commands in /etc/rc.d/rc.local but lfs doesn't use rc.local - at least my version doesn't have it.

So to the question - where is the best place in lfs to put these commands so that they are executed at the correct time and with the required privilege when a user boots the machine?

Thanks

Hi,

Most elegant would be to create your own script in /etc/rc.d/init.d/ and link it to the appropriate /etc/rc.d/rc<number>.d/ directory(ies).

- Pro's:
Own script, no 'alien' stuff in the already excisting scripts.
You decide when it is started (by means of the link in rc<number>.d directories

- (possible) Con's:
Need to write script.
Need basic understanding of the runlevels.

If you need help setting up the above: Just ask.

The BLFS Bootscripts package has the scripts for doing that.

When the computer starts-up, the first thing that it does is to run a program called init. At startup, that program refers to /etc/inittab based on the selected "runlevel" (usually 5).

The typical contents of an inittab will cause all of the commands in /etc/rc.d/rc5.d/ to be executed. All file-names beginning with 'S' (startup) are executed, in alphabetic order. The 'K' files are used similarly at shutdown.

You will notice that all of these files are symbolic-links, and definitely numbered, so that their sequence of execution is certain.

Usually, the inittab then specifies that /etc/rc.d/rc.local is scanned or executed last, if it exists. Its contents and purpose are the same.

What you'll do is to build a command-file containing the necessary instructions, put it (maybe...) in /etc/init.d, and link to it from the appropriate /etc/rc.d/rc.# directories, or from rc.local.

It is very important to understand init and the central role that it plays in the operation of the entire system for the entire duration of its uptime.
