[SOLVED] I deleted my rc.conf.

Hello all,

Well, I am a genius. Or perhaps not....... I just deleted my '/etc/rc.conf' on accident. I meant to remove a different file, but I had been editing '/etc/rc.conf' a lot that night. So when I did a 'sudo rm', '/etc/rc.conf' was what I typed. I finally found a basic backup of it and used that. I even got my internet back to working.

I realize that none of that is relevant. My question is:

Is there some easy way to get all the modules and daemons back in there? I don't know what all modules and daemons where there before, so I don't know which ones to put back in there. I was hoping that there was some neat trick to scan for what modules and daemons that I need in '/etc/rc.conf' and put them there. Any chance of that?

Any advice to help me get out of this mess would be greatly appreciated. I may even put some thought into what I delete next time. smile

Also the backup of '/etc/rc.conf' was named '/etc/rc.conf.pacnew'. And I also noticed that in Midnight Commander all the backup files have a '*' before them. So '/etc/rc.conf.pacnew' appeared as '*rc.conf.pacnew'. However, I renamed it 'rc.conf.backup' before thinking that perhaps it needs to be '*rc.conf.pacnew' in order for the fallback kernel to use it. Is this the case? If so how do I get the '*' back in the name? Because now that I renamed it back to 'rc.conf.pacnew' is doesn't have the '*' before it.

I would think that since the fallback kernel would boot and the regular one would not, then the fallback must use that backup file. I would also think that that file would have to have a certain name in order to be found. If not, that is great, but if so, I need to get it renamed properly. Thanks.

Re: [SOLVED] I deleted my rc.conf.

Don't worry about the * - I'm surprised it's even there.  Maybe that's because it was executable, or something wierd?  Dunno.

As for your daemons, just look at the contents of /etc/rc.d and figure out which ones you need.  Some should be clear (syslog-ng, network, etc...) and others, well, hopefully you know what custom daemons you were running before.

Thanks for the reply. I ran 'hwdetect --modules' and got:

So do I just copy all that and put it in my '/etc/rc.conf'? That seems like way more modules than used to be in there, but that is fine. What about the daemons though? Thanks.

Thanks. So as long as it is named '/etc/rc.conf.pacnew' it will be fine then? That is good. It does need to be 'rc.conf.pacnew' though right? Or can it be named anything? The '*' may just be there to tell me that they are backup files I suppose.

Good to know about the deamons. So do I just add all of them that are in the '/etc/rc.d' to the 'DAEMONS=()'? Thanks.

check hwdetect --help
IIRC, former installer used (i may be wrong but anyway, no big deal):
hwdetect --sound
hwdetect --net

No, it needs be named /etc/rc.conf.   The pacnew file is created by pacman if you've edited your rc.conf, so that you can compare your edited version to the version in the package - nothing will ever use /etc/rc.conf.pacnew for anything.

No, you look through that directory and decide which you need.  I would strongly advise AGAINST adding every single daemon installed on your system into your DAEMONS array - look through the list and figure out which you need.

Re: [SOLVED] I deleted my rc.conf.

Okay, this is what I have went with for DAEMONS:

DAEMONS=(syslog-ng network netfs crond cups dbus hal jack-audio-connection-kit
lircd lircmd mdadm mysqld mythbackend alsa)

I think this should pretty much cover things. Hope so at least.

When it comes to MODULES though I don't know what to think for sure. The only module that I remeber having to add is 'vboxdrv' which I have now. Could I see an example of someone's MODULES to give me a better idea what to look for please?

Re: [SOLVED] I deleted my rc.conf.

my modules line looks like this...

MODULES = ()

that is why arch uses udev, so I don;t have to worry about loading modules. If u need vboxdrv and u know it, then put only that one there. IMO

Re: [SOLVED] I deleted my rc.conf.

yeah...udev should auto load most modules you need. if you still want an idea of what you could put in there, here's mine: ndiswrapper e100 eepro100 mii slhc ac97_bus snd-mixer-oss snd-pcm-oss snd-page-alloc snd-pcm snd-timer snd snd-ac97-codec snd-intel8x0 soundcore

they were mostly in there by default, and I never bothered removing them

I see. I am still new to Arch, having used Ubuntu before. I don't know much about MODULES anyway, I just figured they were important/mandatory. Thanks.

So if I understand right, the DAEMONS are necessary but the MODULES are not? That works for me. Seems odd though, but that's fine. Thanks.

Re: [SOLVED] I deleted my rc.conf.

udev on slow computers can take forever, sometimes its better to turn off udev and hand load modules if u have POS computer. If not then let udev handle your hardware modules and only add them if udev doesn't load a module u need.

It means the file is executable, not that it's a backup. The rc backups just happen to be executable.

Thanks for explaining that. I believe that I have everything fixed now. Thanks to everyone for the great help.
