Arch ignores my rc.conf modules section. That is, because I used a patch/hack/workaround so udev wouldn't take so much time loading(+- 15 seconds). But now, I can't remember the name of nor find the patch/hack/workaround I used, so I can't uninstall it. Is there some way I can find out how to "unignore" my rc.conf modules section, or does anybody know which patch/hack/workaround I probably used?
Thanks!

Can you please post your rc.conf?
There have been some changes lately http://www.archlinux.org/news/changes-t … cklisting/

# LOCALIZATION

#
# LOCALE: available languages can be listed with the 'locale -a' command
# DAEMON_LOCALE: Set the locale during daemon startup and during the boot
# process. If set to 'no', the C locale will be used.
# HARDWARECLOCK: set to "UTC" or "localtime", any other value will result
# in the hardware clock being left untouched (useful for virtualization)
# Note: Using "localtime" is discouraged.
# TIMEZONE: timezones are found in /usr/share/zoneinfo
# KEYMAP: keymaps are found in /usr/share/kbd/keymaps
# CONSOLEFONT: found in /usr/share/kbd/consolefonts (only needed for non-US)
# CONSOLEMAP: found in /usr/share/kbd/consoletrans
# USECOLOR: use ANSI color sequences in startup messages
# VERBOSE: Verbose level (from 1 to 8). man 3 syslog for level info

# Declare each interface then list in INTERFACES
# - prefix an entry in INTERFACES with a ! to disable it

Your MODULES array is empty, how do you expect rc.conf to 'ignore' it?
And as Karol says, you really need to merge your .pacnew files (or update your system altogether).

My MODULES array is empty because I emptied it. But, it is being ignored, because of a patch/hack I installed. I want to know the name/url of that patch/hack, so I can undo it.

But what was wrong? The modules weren't loaded or weren't ignored? What were you trying to accomplish?

I can't speak for everyone, but imo there is no way anyone can identify the patch/hack/workaround you used without more details. Any chance you know what file(s) changed when this p/h/w was applied?

No it is not:
cur_work$ gr MODULES /etc/rc.conf
# MODULES: Modules to load at boot-up. Blacklisting is no longer supported.
MODULES=(acpi-cpufreq)
cur_work$ lsmod | gr acpi_cpufreq
acpi_cpufreq 5809 1
freq_table 2491 2 cpufreq_ondemand,acpi_cpufreq
processor 24328 3 acpi_cpufreq
mperf 1315 1 acpi_cpufreq
Module blacklisting is, however, ignored -- please read the news post...

Leonid.I - did you not read his posts? He applied some unidentifed hack to his system, which he now blames for disabling the automatic loading of modules from the MODULES array.
The fact that it works for you is totally irrelevant.
Offline
Fair enough...
The only relevant patch from initscripts git is
<http://projects.archlinux.org/initscrip … 25c0e17782>.
MODULES is parsed in rc.sysinit, so this is what we need to see.

The 'hack' you speak of was to work around usage of /lib/udev/load-modules.sh, which we no longer use. I'm not sure where you came up with the idea that it would cause MODULES to be ignored for purposes of loading modules because that was never the case -- it would only cause MODULES to be no longer useful for purposes of blacklisting modules.
This is all now irrelevant because, as I mentioned, load-modules.sh no longer exists. But again, this never affected module loading at bootup and I fail to see how you're making this connection. If you were to reinstall udev and initscripts, you'd be back to square one. In the future, perhaps you could be more mindful of such changes you make to critical pieces of the OS.

Thanks, I'll try reinstalling udev and initscripts. But, I am sure the hack I used had the effect(direct or indirect) that my MODULES section in my rc.conf would be ignored.
I'll try reinstalling those packages, and report whether the problem was solved.
Offline
Reinstalling udev and initscripts didn't seem to work. I disabled MOD_AUTOLOAD, although I read it'd be ignored anyways. My /etc/udev/rules.d is empty, but my /lib/udev/rules.d is not.
Hwdetect --modules
yielded no modules at all. I tried adding a random currently not-loaded module to my /etc/rc.conf module list: crc-itu-t. I don't have any idea what the driver is for, but I thought I could use it to see wheter it get's loaded or not. Lsmod | grep crc-itu-t yields nothing, and no log file in /var/log mentions "crc-itu-t" (I used "find /var/log -print | xargs grep "crc-itu-t"")
For clarification: I installed an (unofficial) hack, from outside the repo's. Probably almost all other arch users didn't install that hack, and this hack I used doesn't have anything to do with the changes to module blacklisting(here).
I tried to find this hack I used, so I can know what it did, and undo that. But, I can't seem to find it anywhere, and I installed the hack quite a long time ago, so I don't remember what it changed.
Perhaps the fact that hwdetect --modules lists nothing helps finding the problem.
Thanks for the help so far.

At this point, how about you upgrade the system and then force install the kernel. That might work. Using -f flag however is not always recommended, but its worth a try. Failing that, simply re-install. Hopefully you have your /home on a different partition.
There's no such thing as a stupid question, but there sure are a lot of inquisitive idiots !

After reinstalling my kernel, hwdetect --modules works again. My modules listed in rc.conf seem to load properly again.
Thanks for your help!
