fortuanately i got out of it by then, version 7 hates my hardware, i was using 
6.x  for a couple years (off line, glad i saved local archives), when it first 
hit V6, not surprisingly it kept trying to sneak in and was resistant to

liked the ability to specifically break packages by not installing "required 
code", i don't need my media player to talk to the world.

not at all surprised by the source.  like i said rh spent good money to take 
over centos.  also used scientitic linux which is somewhat fixed.  Then there 
are the impossible to see/use colors mc wants to use, i started using computers 
over leased lines on decwriter 2 printing terminals, I can edit in b/w, though 
i played with mc's colors as well.  that's why i love linux, most problems are 
easy and have well documented solutions.

now, if i just knew how to search for "root-", which is impossible with modern 
search engines, they insist on processing quoted text and turn punctuation into

in any case, that's why i know how to futz with zeronconfig/avahi.  figured it

  CentOS is a free Redhat clone.  Zeroconf (Avahi) is Lennart-ware that
you-know-who got into Redhat's OS.

  It should not be mandatory in Gentoo, per se.  If you have avahi
installed, try "emerge -p --depclean avahi" first, before doing it for
real.

Re: [gentoo-user] dhcpcd: disable zerconf

[mad.scientist.at.large]

it's mostly from the evil centos days (after it was bought out).  I assume 
similiar files are involved with gentoo, as earlier response suggested.  when 
my health improves i'll be putting gentoo on several systems and a couple 
ancient servers, did get it working nicely on one desktop.  I like  a steep 
learning curve, but not while i'm recovering.

Re: [gentoo-user] dhcpcd: disable zerconf

[Lucas Ramage]

Is your scenario related to running Gentoo on a workstation?

I am using gentoo as a hypervisor for lxc and my veth interface for my
guest is getting assigned a 169.254.x.x address (host side). I can't see it
from inside the guest, but it's screwing with my routing tables.

that works.  myself, i like to totally misconfigure it and then change access 
to read only even for root, usually takes care of updates starting it.  i've 
also sabotaged one of there scripts so it just always returns a 1, i.e. error,

Do you mean ipv4ll? Add noipv4ll to /etc/dhcpcd.conf .

While this is going to cause a bit more building, I personally tend to
redirect kernel build output.  I add O=/var/tmp/linux to all my make
commands, which leaves /usr/src untouched and builds faster besides
(tmpfs).

The main downsides to this are:
1.  Make can't re-use objects from previous builds, so rebuilds will
go slower.  Though, IMO this is worthwhile if re-using those objects
causes issues (which I assume is due to imperfect makefiles).
2.  When building packages that install kernel modules the prepared
sources won't exist.  This requires going back and re-preparing them
(make O=/var/tmp/linux modules_prepare).  For packages like zfs-kmod
that use Module.symvers this is even more painful as you can only get
that by rebuilding the whole thing.

[gentoo-user] dhcpcd: disable zerconf

[Lucas Ramage]

Hello,

How does one disable zerconf for dhcpcd or at all in Gentoo for that matter?

Search results gave me this little snippet but it doesn't apply to Gentoo.

[HowTo Disable the “ZEROCONF” in Linux](http://blog.omotech.com/?p=1005)

[bash] # vi /etc/sysconfig/network

NOZEROCONF=yes # or no (either answer will disable the “ZEROCONF route”)

And here again it's the same thing (Fedora).

[Disable the zeroconf route](
https://linuxstgo.wordpress.com/fedora-16/disable-the-zeroconf-route/)

Thanks,

Based on the output you supplied, objtool isn't happy with
fs/ext4/indirect.o and fs/ext4/extents_status.o.
Did you do 'make clean' prior to building the kernel?
If you did, it might be worth doing a 'make mrproper' before
rebuilding the kernel.
Don't forget to back up your .config before running mrproper.

Let us know how you go.

[gentoo-user] [OT] lost menus in seamonkey

[pat]

Hi,

Sorry for this off topic, but I need help. I've killed the seamonkey, 
because it didn't respond for a long time (an hour) and eats about 50% 
of CPU. When I restart it I have all tabs, but lost all menus - no menu 
on right click no menu items under File/Edit/... .


Can someone help?

Thanks
