Re: WITHOUT_MODULES in /etc/make.conf doesn't work
from Polytropon free...@edvax.de: Yes, /etc/src.conf uses WITHOUT_* on a per-module basis, so you need to explicitely name the modules not to build. But you're right, there's only WITHOUT_USB (for not building the USB-related parts), so going with kernel configuration would be a good point to start -- the more precise you can define your test setting and its variables, the better you can diagnose the problem. In /etc/make.conf, you could use MODULES_OVERRIDE to define the set of modules you want (because only _those_ will then be build) and keeping their functionality out of the kernel. In this case, you have control over your test setting using the modules. The same files offers NO_MODULES=yes to avoid building modules at all (use custom kernel instead). If you decide to use WITHOUT_MODULES, you can define the set of modules you want to avoid building, everything else will be built. Would WITHOUT_MODULES= ulpt work better in /etc/src.conf than in /etc/make.conf ? No, /etc/src.conf as (according to its manpage) a defined set of variables that will be considered when building (or _not_ building) certain modules. Besides the toxic (?) ulpt.ko, there are a lot of modules that would never be used on my hardware, and other modules that could be built in the kernel as non-modules (such as support for msdosfs and ext2fs, which I don't want to be without). That's a good setting for using a custom kernel and not even building the modules for the non-used functionalities. :-) I suppose modules save RAM by being loaded only when needed, but see the virtue of NO_MODULES=yes or MODULES_OVERRIDE in combination with putting everything needed in kernel config. Building WITHOUT_USB would cause a severe loss of functionality, USB sticks, USB hard drives, even USB mice and keyboards wouldn't work. from Jakub Lach jakub_l...@mailplus.pl: Try with: WITHOUT_MODULES= usb/ulpt I'll have to try that on my build/update of FreeBSD 9.0_STABLE i386 on USB stick. Thanks for the hint! This would be from the USB stick but with source base directory /STABLE1/usr/src (on hard drive). I had already built FreeBSD 9.0_STABLE i386 on the USB stick from FreeBSD 9.0_STABLE amd64, and was successful booting that USB stick. Sort of a dirty trick that you have to use usb/ulpt as opposed to ulpt, and a deficiency in the documentation. Now is there any way to prevent ulpt.ko from loading when a USB printer is connected?

Sort of a dirty trick that you have to use usb/ulpt as opposed to ulpt, and a deficiency in the documentation.

Well, the info that uname(1) prints out is generated from the source code at compile time. Recompiling the kernel, or updating the kernel via eg. freebsd-update(8) are the only ways to change it. If you're asking about the perennial I just security-patched my system with freebsd-update, but uname still shows the old patch-level thing, then yeah. Unless freebsd-update supplies you with a whole new kernel image, which only happens when a security bug involves the kernel, then the uname output will not be changed.

Well, the info that uname(1) prints out is generated from the source code at compile time. Recompiling the kernel, or updating the kernel via eg. freebsd-update(8) are the only ways to change it. If you're asking about the perennial I just security-patched my system with freebsd-update, but uname still shows the old patch-level thing, then yeah. Unless freebsd-update supplies you with a whole new kernel image, which only happens when a security bug involves the kernel, then the uname output will not be changed. It's a flaw, but any solutions involving being able to tweak uname settings without changing kernels open up a whole can of security worms[*] which are, on the whole, worse than living with some mildly outdated data.
