Also, XFS is compiled right into the kernel, not as a module (I believe, because there's no module xfs in /lib/modules/3.2.6-gentoo. AFAIK, by default XFS is mounted with acl support.

[gentoo-user] gentoo-sources menuconfig feature/weirdness
Hello all,
Usually on gentoo when gentoo-sources gets updated, updating the kernel
went as follows:
eselect kernel set {new kernel}
cd /usr/src/linux
make menuconfig
and then there was a totally clean config which I would then customize
for the specific setup.
On one box I am currently running 3.1.6-gentoo
When I start make menuconfig for 3.2.1-gentoo-r2 it would appear as if
it got my current config from somewhere, eg local version.
Is this a new feature?
To make sure of this I unistalled all gentoo-sources pkgs, deleted
everything /usr/src/linux*
installed the latest gentoo-sources
yet it still seems to find the current config somewhere
Anyway, just wondering,,
Regards,
Coert

That is exactly how you do it. Copy a .config over and run make oldconfig I am definitely going to try this. Yes, there could be incompatibilities. This might happen once every few years when you do an upgrade over 10 version numbers. But that can be fixed. Not doing it this way means a very high likelyhood of the machine not booting with every single upgrade, plus the huge amount of work it takes to go through everything in menuconfig. indeed, especially when the server is stuck in a far away rack. The choices are simple, - low risk of occasional breakage - high risk of frequent breakage Thank you all

Alternatively, it may be possible to dd the partition and pipe it to clam (not sure if this will work with a whole partition instead of a file) using something like: dd if=/dev/sda1 | clamscan - Alternatively, you can use Knoppix and Fprot, bitdefender and clam.

It has indeed happened to me with an IDE PATA disk.
Try first only to change only your grub config.
Then if you see that the kernel boots fine, you can change /etc/fstab.
If you want you can even use LABELs in fstab.
give your ext{2,3} partitions labels with e2label
and change the device node eg /dev/hda1 in fstab to LABEL=yournewlabel

Now I am reading through /usr/share/portage/config/make.conf.example My CFLAGS on that machine is the default currently: CFLAGS=-O2 -pipe But according to http://www.gentoo.org/doc/en/gentoo-amd64-faq.xml#cflags I can make it: -O2 -march=core2 -pipe Is this entirely necessary? Will it cause a big improvement? If I do change, how do I recompile everything? (like --newuse for USE changes?) Thank you, Coert Waagmeester

I keep changes of my /etc with git and I would like to include /var/lib/portage/world file into the repository. Can I safely do: mv /var/lib/portage/world /etc/portage ln -s /etc/portage /var/lib/portage/world Will portage update handle it properly? Using hardlinks seems to be more cleaner way, but for some reason I don't want to use it for this task. It should work. Just try it out, but make a copy of your world file before. Should be easy to switch back if anything fails. Afaik, the creation of the symbolic link should look like this: ln -s /etc/portage/world /var/lib/portage/world Thanks for the correction, you're right, of course. Nevertheless, I've considered that using hardlinks is most porper way to solve this task. It basically do what I need, make another reference to the file under needed directory; without introducing compexity. What about a bind mount? Rgds, Coert
[gentoo-user] distcc and USE flags
Hello all, Still new to gentoo. I use RHEL a lot. If I want to set up an x86 distcc solution, do the USE flags need to be the same on all machines? Trying to setup/compile all desktop apps on one machine with two assisting in compilation. Regards, Coert Waagmeester
