I have noticed in the slack forum some confusion regarding the use of sysfs and the 2.6 series kernels. Well, I was unsure as well, and did a bit of reading. I still have a few questions.

I started looking around in the kernel documentation, but was disappointed with the lack of guidance on the subject.

The key points to get this working correctly on Slackware seem to be:

1. Give sysfs a mount point

mkdir /sys

2. Put an entry in /etc/fstab

sysfs /sys sysfs defaults 0 0

(Note, this is only for 2.6 series, if you run 2.4 series kernels as well then you need to start thinking about the noauto option, and a script to mount sysfs only when required.)

Patrick says that Slackware 9.1 or later is 2.6 ready, and it is, but you still need to make the changes shown above.

Documentation from various sources also suggests that the initscripts (and shutdown) that start your linux system need to be modified to mount sysfs, but no change appears to be necessary in Slackware, I believe this is due to the line in /etc/rc.d/rc.S:

/sbin/mount -a -v -t nonfs,nosmbfs

which mounts the stuff found in /etc/fstab

however, I do not know whether sysfs should be mounted early like /proc is, or not. It does not appear to make any difference on my system.
Anyone have any comments on this?



I am running Slackware current and kernel 2.6.4

hey,

when i was switching to 2.6 under slackware 9.1 i used this article as a reference. it goes over the /sys stuff, including how to edit init files so that /sys will only be mounted if it's 2.6.

personally, i didn't need to have the option to still boot 2.4, so i didn't bother with that. if that's your case too, you can put "defaults" in the sysfs line in /etc/fstab instead of "noauto" and it will work fine.

the article is at http://linuxdevices.com/articles/AT2184776431.html

cheers,

I didn't read any documentation, I did not have the /sys thing and everything work fine. Will try to do that sys thing to see what I can get out of it.

Hey carboncopy I guess it was related. I couldn´t mount my digital camera (a mass storage scsci device) until I setup sys. I dunno but guess its related.
