I used to have 3 (even 4) same-hardware machines (well same MBO really)
in daily use, and the local mirror is not an overkill long run. And if
you look for security, then also Air-Gapping and cloning is a perfect
solution, because you get a clean clone for online with an Air-Gapped
that does not see online...

Some peple like rather btrfs ...

I had written a lot about Air-Gapped and cloning on the Forums, but
maybe moderators would call it "blogging" if I gave you the link.

btrfs I never used OTOH.

We are talking grsecurity-patched (kind of stable[*]) kernel sources,
the =sys-kernel/hardened-sources-4.4.8-r1 package [**].

I read most of the discussion, and I could easily patch the gup.c and
mm.h in question, but those files need to be patched before application
of the grsecurity patch, and that is a little more complex work.

Has anybody done this, as I have limited time available to practice user
patching (which in its simplest form, I was able to do here:
>=dev-libs/nss-3.24 - Add USE flag to enable SSL key 
https://bugs.gentoo.org/show_bug.cgi?id=587116#c2 ), in case it can be
done with user patching, of course.

Anyone?

Regards!

Re: [gentoo-user] I finally ditched acroread

2016-10-24 Thread Zhu Sha Zang 
Hey dude, i have acroread installed but use okular since long time ago. 
In fact my i was in doubt if acroread still installed. I'll uninstall 
acroread, but how to recompile packages without 32-bit ABI? Is there a 
smart way or I need to change e recompile each one?



Best regards.

Acroread is only available as a 32-bit binary and it required that
_89_ packages be built with a 32-bit ABI use flag.  [There are various
other reasons to dislike acroread, but that's the one the really

When I noticed that the latest versions of Qoppa's PDFStudio has added

upgrade.

Emerge is now busy rebuilding those 89 packages without the 32-bit ABI

Well, the question mark is gone once I am connect to a network. But I still
have those messages and no auto-reconnect. I downgraded to 1.0 for now until

I have one box that I run emerge --sync on, and then export /usr/portage
with nfs to a few other gentoo boxes. Works well. For eix, you can do
eix-update on the nfs-clients. I have been experimenting with building
once and using the nfs-server as binhost. Small variations between the
boxes have so far made me abandon that, but a single version of
/usr/portage has given me no headaches.

Why not just share everything via bind mounts in this case?  I'd think
that would have less overhead than rsync/http and then you're not

I use a similar setup for LXC containers running over a gentoo box,
except that my box is setted up to publish the binary packets on a
specified directory that is accessible via HTTP. My LXCs take the binary
packages from this HTTP location and do their normal stuff afterward.
The host box is also a local rsync mirror.

My use case is basic: 2 home computers, I do emerge et. al. on the
faster one and produce binary packages to be used on the other one,
which doesn't even need distfiles, just portage tree plus binary
packages.  I copy stuff between boxes with rsync via ssh. Simple
enough and it seems to be working fine.

It really depends on your situation.

I run Gentoo containers and I typically just bind mount /usr/portage
and distfiles from the host, and that works just fine.  When I was
running Gentoo VMs I had rsync running on a Gentoo box and just shared
out /usr/portage and put it at the front of my mirror list (I also
shared distfiles via http I believe).  If you already have the
services installed it is pretty trivial to set up either and it will
speed things up.

People will go even further if they have large number of Gentoo boxes
and run their own repositories that isn't live-synced with Gentoo's,
allowing for a testing/release cycle.

In general though portage will figure out if any packages moved in the
repo no matter how you sync it.

Yes. And you will see the same output that your see at the end of emerge
- --sync (the profile updates phase, whatever it's called) when you run
emerge. To update the eix database you need to run eix-update.

But a more elegant solution is to emerge app-admin/gentoo-rsync-mirror and
setup your own rsync mirror.

That can be useful if there aren't any other options, but it tends to
be a hassle.  You have to crank up the DPI setting pretty high on the
rasterization operation, and then you end up with image files that
some printers seem to choke on. Our (admittedly ancient) LasertJet
8150 seems to be particulary bad handling large, hi-DPI image files.

portage also changes the content of /var/cache/edb, and in some

has changed.

Unless things have changed massively in the last 3-4 years, you almost 
certainly were using xv without really knowing about it. With just 'x11', 
you're forced into using software scaling instead of hardware scaling, which 
massively slows things down. And hardware scaling has been a feature of 
essentially every video card since, I dunno, 1994 or earlier? And the xv 
extension has been available since 1991...
