Final step issue at migrating to openrc! [SOLVED]

I'm currently migrating my system to openrc.

I can't retrieve location of the description file for the modules kernel should load.

Its /etc/conf.d/modules in baselayout2.

Most things are loaded automatically now, so you may not need explicit load instructions in /etc/conf.d/modules

Thanks for you reply.

ASAIU, the figure is "please migrate content of file A to file B".
What you're pointing at is file B, but I think my problem is that I can't find file A.

One thing is for sure, my kernel has been configured to minimize module calls as much as possible.
I know kernel only use 2 modules: one is SCSI, I can't remember the other one.
Whether this modules are loaded at boot time, I can't tell.
If they are not, I could be an explanation for the lack of directory /etc/modules.autoload.d/

Rebooting should not be too risky, though.

I'm just trying to do everything right at first shoot.

Thanks for your attention and interest.

I finally made it. It's working fine too.

The two concerned modules are:

CaptainBlood,

The scsi_wait_scan.ko kernel module allows SCSI drives to not spin up until the kernel scans their address on the bus, rather than powering up when you switch on. This is a good thing as it reduces the peak load on the +12v used to power the drive motors. If this feature can be used, the drive spin up peak is spread over a longer period.

As far as I know, its only useful with real SCSI drives. PATA drives certainly don't support this option. I'm not sure about SATA drives.
Its not so important as it once was as the moving mass in drives is much lower than in the 'good old days' and motors need less power anyway.

xt_policy.ko is part of IPtables - your firewall so that needs to be in place before your internet connection goes live.

look in lsmod to see if these modules are loaded.

Actually I don't have any true SCSI device, but ASAIK it needs to be activated at some point in kernel for USB key drive to operate.
It's been a while now, but I think there no other option around I can remove without my test key to fail.

Although I already did a lot for a very lean kernel, I kept all firewall option activated because this system it aimed to be a firewall between internet and my home network,
I guess I have a lot to understand before it gets there.

By the way, this openrc brought my 586@450, PIO4 an asskicked boot time.

Thanks a lot for your attention, support and interest.
