I used to use a portage tree shared over NFS. One thing that is worth 
considering, if you haven’t, is having the remote host manage tree syncing. 
This would remove the need for the laptop to be involved in the sync.

Also, I generally would try to avoid updating the system while out and about, 
so that when I am updating it is a local network operation. Obviously this 
won’t work if you need a package when out and about, but if you are local to 
the server every night or couple of nights, it would significantly reduce the 
pain of updates.

[Franz Fellner]

And another great one!
Just have a look at package.use/mkvtoolnix and you will see your problem.

# echo "qt5" >> /etc/portage/package.use/testuse
# emerge @preserved-rebuild
--- Invalid atom in /etc/portage/package.use/testuse: qt5

If it isn't obvious:
# man portage
-> GLOSSARY -> DEPEND atom

It looks like you have a version included but did not put a =, < or > in
front.  Could be the opposite as well.  You have a = in front but no
version on the end.  I do this often since I copy and paste.  One would
think I'd remember to get it right but, I'm me.  ;-)

Here is a couple examples.

dev-libs/redland -mysql
app-office/libreoffice mariadb
>=media-libs/babl-0.1.72 introspection
>=media-libs/freetype-2.8 harfbuzz

Notice that without the = characters you also can't have a version.  If
you do have a version, you have to have the = in front.

Hope that helps.

[gentoo-user] Rasp-Pi-4 Gentoo servers

[james]

I'm thinking about setting up a pair of Rasp-Pi-4 as DNS servers with 
4GB of ram. Is that enough ram for a DNS server?


https://www.amazon.com/CanaKit-Raspberry-4GB-Starter-MAX/dp/B07XPHWPRB


https://wiki.gentoo.org/wiki/Embedded_systems/ARM_hardware_list

If 4GB is not enough, there are some boards with 8GB
of ram.


What about running postfix on a third  board?

https://samhobbs.co.uk/2013/12/raspberry-pi-email-server-part-1-postfix


All feedback is encouraged. It will not be a high volume postfix email 
system. As far as the DNS servers, it seems I vaguely remember some 
software or filters to prevent hack attacks, that just overwhelm  DNS 
servers; or something like that. It just lowers the data flow rate.


It seems this is popular, and which version of USB 3.?
to use on a stick, as now usb sticks can have large capacities now (T+).

Surely I'll back up the mail (spool & such) to a secondary hard drive on 
another system.


It this all goes well, surely I put a web server on a fourth board.

https://pimylifeup.com/raspberry-pi-nginx/


Granted those links are not centric to embedded gentoo, but they do 
cover a lot of what is needed.


Further suggestions are most welcome. This is a fun to do project, 
useful as it would basically be easy to duplicate, so I can travel 
anywhere, get a few static IPs and deploy a small business, 
self-sufficient, network.


So the Rpi4 boards will all need their own unique, static Ip. But, 
another questions is while they are running as 4 distinct gentoo 
servers, could they also double as a quad-gentoo cluster?


https://www.picocluster.com/collections/raspberry-pi4


Security pointers are most welcome too.
The eventual idea is to have a fixed home network, but
be able to travel around in my pickup/cabovercamper
and have what I need right there, or provide it to friends as a ready to 
go small network. Embedded Gentoo,

low-power hardware and 100% (gentoo) source driven).

The S20 (520G ram) phone would server as the router.
(2)  5G cell phones running on (2) different 5G  service
vendor, could make the services and cluster multi-homed?

Would all of this work with just IP6 and a fancy cell phone, running 
gentoo?  We shall see.

Re: [gentoo-user] speedup remote portage

[Michael Jones]

You can separate the package directory and distfiles directory from the
ebuild tree.

PORTDIR="/usr/portage"
DISTDIR="/usr/portage-distfiles"
PKGDIR="/usr/portage-packages"


That lets you keep the ebuilds local to your laptop.

Re: [gentoo-user] speedup remote portage

[Michael Jones]

When you say you have a remote portage. What do you mean?

The actual portage tree, with all the ebuilds? Or something else?

[gentoo-user] speedup remote portage

[William Kenworthy]

Hi,

    due to space considerations on my laptop I have moved portage onto a
network share (moosfs, mfsmounted) - slower but works fine.  However,
being a laptop trying to update/install when out and about is both very
slow and network intensive through a vpn - again, it works but is even
slower to the point of not always being practical

Is there a way to localise/speedup portage scanning parts of the
update/install process?

1. put it on a squashfs share to save space (the laptop is running btrfs
with compression so I don't think that will get me much)

2. put portage on an sd card and mount it when necessary

The laptop is a Surface Pro4 so expanding the storage is not practical -
though I could shrink the windows partition a little more.

So did I, but sometime ago something must have changed. Might be even
two or three months ago. Since than, the wired interface on my notebook
is not longer managed...

And I don't find the reason. Any help is appreciated...
