I mean there is a problem with new kernel version. Not sure but I suppose open-vm-tools sources are installed into kernel sources tree. And if you install new kernel, open-vm-tools sources are not moved to the new kernel-sources tree. Whenever I installed new kernel-sources and re-created link /usr/src/linux pointing to the new sources, I had to re-emerge open-vm-tools too... I don't use open-vm-tools so I don't know how they work. I do know vmware and virtualbox's stuff though - basically the same as any out-of-tree module package. The ebuild takes care of the nitty-gritty and builds the modules against whatever /usr/src/linux points to. Is open-vm-tools the same? Actually, it's open-vm-tools-kmod that builds the kernel module. open-vm-tools is the userspace components that do not have to be rebuilt after a kernel upgrade. Otherwise, yes, that's exactly how it works. Deploying a new kernel version is a complex affair anyway. You have to configure the thing, carefully look out for new and changed config options, run FOUR make commands, edit grub.conf and do a lot of testing. Now you have to add one extra tiny little command to the end. It's one little bullet point in your process. It isn't really all that complicated, and there are plenty of tools to help you automate most of it (i.e. genkernel).

installing
udev-197 and the config scripts will go in the correct place.
You should do this before rebooting the machine because lvm2 won't
work until
its udev scripts are in the correct directory.
Running this command (all in one line):
emerge -p1 $(for p in $(qfile -Cvq $(find /usr/lib/udev/) | sort -u); do
echo =$p; done)
should re-emerge all packages that still have files there. After that,
/usr/lib/udev should no longer exist. If it still does, then there are
files in it that don't belong to any package. Check them manually and
delete them as needed or move them over. Then delete /usr/lib/udev.
Or, without a loop (easier to read and type, IMHO):
qfile -Cvq /usr/lib/udev | awk '{print =$1}' | xargs emerge -pv
or, using gentoolkit instead of portage-utils (slower, but will not fail
if the installed version of a package no longer exists):

The problem is you are trying to downgrade sys-fs/udev but not
virtual/udev. If you want to force using udev-171, you need to mask both
the real and virtual atoms. Try this in /etc/portage/package.mask/udev:
=sys-fs/udev-181
=virtual/udev-181
Then emerge -avuD1 udev and see if that fixes it.

While I don't know Nilesh's background, I have no reason to really doubt what he says here I seem to find a lot of posts on the web where people mount using UUID and they aren't clear as to whether they have an initramfs or not. I'll consider this solved for now with one caveat that it's unclear when you build the initramfs what tools have to be placed within it to make the following true. 1) No initramfs - mount by device name only 2) With initramfs - mount by device name, label or UUID. Thanks VERY MUCH for taking the time to find this. I'm removing the offending option from my grub.config file. Cheers, Mark The other wiki has a page[1] about building an initramfs that includes a section on writing a linuxrc script to support exactly that. I have since switched to Genkernel, but I used to have a hand-built initramfs containing very little besides that script block.

Non-incremental variable means it will reset whenever you assign to it. Thus, all you need to do is specify only what modules you want; anything not specified will be excluded. -- ♫Dustin

Don't you mean dchpcd (the c stands for *client*, dhcpd would be the DHCP daemon granting leases to clients)? If so, and if you don't mind using the same settings for all network interfaces, have a look at /etc/dhcpcd.conf, which has an option option ntp_servers. I'd guess that disabling this would do what you want. Actually, you can use /etc/conf.d/net to turn off receiving NTP configuration for just one interface, if you want. The `dhcp_IFACE` parameter takes several values, one of which is `nontp`, which will do exactly that. For example: config_eth0=dhcp dhcp_eth0=nontp When you find the net.example file, you'll find that documented under GENERIC DHCP OPTIONS, about midway through the file. Regards, -- ♫Dustin

[gentoo-user] crossdev, alternate root, and build dependencies
I am trying to understand and use crossdev to build Gentoo for my
Raspberry Pi, and I have a couple of questions. I was able to
successfully build a toolchain::
crossdev -S -t armv6j-hardfloat-linux-gnueabi
This correctly installed binutils, gcc, glibc, and linux-headers::
equery list cross-armv6j-hardfloat-linux-gnueabi/*
* Searching for * in cross-armv6j-hardfloat-linux-gnueabi ...
[I-O] [ ] cross-armv6j-hardfloat-linux-gnueabi/binutils-2.22-r1:0
[I-O] [ ] cross-armv6j-hardfloat-linux-gnueabi/gcc-4.5.4:4.5
[I-O] [ ] cross-armv6j-hardfloat-linux-gnueabi/glibc-2.15-r3:2.2
[I-O] [ ] cross-armv6j-hardfloat-linux-gnueabi/linux-headers-3.6:0
I then copied the configuration from
/usr/armv6j-hardfloat-linux-gnueabi/etc/portage to an alternate
location, so I could modify it without impacting the crossdev toolchain.
Next, I started to emerge some ebuilds into a staging directory using
the following commands::
export CBUILD=$(portageq envvar CHOST)
export PORTAGE_CONFIGROOT=/home/dustin/rpi-build/configroot
export ROOT=/home/dustin/rpi-build/buildroot/
export PORTAGE_TMPDIR=/home/dusitn/rpi-build/tmp
emerge --nodeps baselayout
emerge --onlydeps baselayout
The first pass completed successfully, but the second failed to build
psmisc::
checking for tgetent in -ltinfo... no
checking for tgetent in -lncurses... no
checking for tgetent in -ltermcap... no
configure: error: Cannot find tinfo, ncurses or termcap libraries
config.log shows this::
configure:3970: checking for tgetent in -lncurses

ncurses did get installed in the alternate root::
ls -1 ${ROOT}lib/libncurses*
/home/dustin/rpi-build/buildroot/lib/libncurses.so.5
/home/dustin/rpi-build/buildroot/lib/libncurses.so.5.9
/home/dustin/rpi-build/buildroot/lib/libncursesw.so.5
/home/dustin/rpi-build/buildroot/lib/libncursesw.so.5.9
Now, I've found that if I install ncurses in /usr/${CHOST} instead of
${ROOT}, psmisc will build successfully. I am thus confused on where
things are supposed to be built. The Cross Development Guide says not to
install pieces of the toolchain in /usr/${CHOST}, but some ebuilds, like
openrc, have explicit RDEPENDs on them, so emerge pulls them in. I'm not
sure how to resolve this seeming catch-22 where I can't install runtime
dependencies in /usr/${CHOST}, but I also can't install build
dependencies in in ${ROOT}.
I am hoping to have this process scriptable, so my current method of
just installing missing build dependencies in /usr/${CHOST} after
something fails won't work. Any pointers would be appreciated.
Thanks,

I was able to use a hex editor to modify the white list at one time, but it didn't matter because the hardware radio switch doesn't work with different cards, either, leaving the radio in a permanently off state. Someday, I'll get a more professional notebook, but until then, I'm stuck with the patched broadcom-sta. It does seem to be working fine for now, so I'm not terribly worried.
