 Posted: Mon Mar 17, 2014 11:28 am Post subject: [Solved]Mask overlay by default |
 |
|
Hello all,
Apologies if this is answered somewhere obvious, but I haven't been able to turn up the answer I want yet.
I want to use an overlay but select only specific packages from it, defaulting to selecting from the main tree rather than the overlay. I don't mind if that means masking the overlay and selectively unmasking, but I don't want to use overlay packages if it is already in the main tree. Is there a way to do this, hackish or otherwise?

Why not a local overlay without any others.
I copy interesting ebuilds there.
But may be symlinking directories from layman is possible also to get the updates ... |

Set PORTDIR_OVERLAY with PORTDIR as the first entry.
In other words if PORTDIR_OVERLAY="/usr/local/portage" and you want gentoo repository to be seen 1st then do this
PORTDIR_OVERLAY="${PORTDIR} /usr/local/portage"
http://wiki.gentoo.org/wiki/Overlay
You can also mask specific packages with <pkg name>::<repository> in package.mask

1) Well, to mask all packages of an overlay the syntax in /etc/portage/package.mask is:
*/*::overlay_name
2) To unmask a package from specific overlay the syntax in /etc/portage/package.unmask is:
package_name::overlay_name
Obs.: if you put just package_name in package.unmask, it's by default considered the official Gentoo tree. Which is equivalent to package_name:: gentoo. In other words, writing sys-kernel/gentoo-sources or sys-kernel/gentoo-sources::gentoo is quite the same.
3) My configuration files:
I have four overlays and use just one package of which one of them.
My /etc/portage/package.mask:
*/*::rion
*/*::sunrise
*/*::poly-c
*/*::x11
My /etc/portage/package.unmask:
dev-util/eclipse-sdk-bin::poly-c
sci-geosciences/qgis::rion
media-video/periscope::sunrise
dev-libs/weston::gentoo ## official tree weston unmasked, instead of the x11 overlay one
This way, I have all packages of a specific overlay masked but the one I need.

Thanks Anon-E-Moose, that's exactly what I'm looking for
I had found reference to that before but it must have been an old post as I hadn't realised the ordering had changed, explaining why it didn't work for me.

Yep, that's also a valid way to do it. I do that with the two overlays that I have rather than adding PORTDIR to PORTDIR_OVERLAY
ulenrich's suggestion also works.
It just depends on what the user wants to do.
Telemin, glad it works for you.

Anon-E-moose, I had problems with weston. I wanted Gentoo's tree weston, but portage installed the version in x11 overlay (which was newer). That's why I mask all overlay and unmask package by package. Is it possible to make this using that method you describe?

It should work.
From the link about overlays that I posted
| Quote: | | Unless the PORTDIR_OVERLAY variable has been modified as described below, the default gentoo portage tree will have a priority of -1000. That means that all other overlays take precedence. That is the default behavior, because overlays are designed to "lie over/on top" of the portage tree. |
But by putting PORTDIR first in the overlay ordering it should take gentoo first then overlays.
Note: I don't have my system set up this way, so I haven't tested it.
Note 2: There is a make.conf in the layman directory, where it puts the overlays in order of searching, but I'm unsure if it overrides /etc/make.conf or is searched after. A simple test would probably give a definitive answer.
I'll probably try it later and see what the results are.

Ok the docs aren't the easiest to make sense of (or I'm too thick headed)
Original lines from /etc/make.conf (or /etc/portage/make.conf)
| Code: | PORTDIR=/usr/portage
PORTDIR_OVERLAY="/usr/local/portage"
source /usr/local/portage/layman/make.conf |
with these from my layman make.conf
| Code: | PORTDIR_OVERLAY="
/usr/local/portage/layman/xmw
/usr/local/portage/layman/init6
/usr/local/portage/layman/poly-c
$PORTDIR_OVERLAY
" |
Yields this
| Code: | PORTDIR="/usr/portage"
PORTDIR_OVERLAY="/usr/local/portage/layman/xmw /usr/local/portage/layman/init6 /usr/local/portage/layman/poly-c /usr/local/portage |
when "emerge --info |grep PORTDIR" is run.
Running "emerge -pv mesa" gives me
| Code: | | [ebuild R ~] media-libs/mesa-10.1.0::init6 [10.1.0::gentoo] |
It tries to pull from ::init6 instead of ::gentoo
------
Changing the lines quoted above for /etc/make.conf to
| Code: | source /usr/local/portage/layman/make.conf
PORTDIR=/usr/portage
PORTDIR_OVERLAY="${PORTDIR_OVERLAY} /usr/local/portage ${PORTDIR}" |
Yields this
| Code: | PORTDIR="/usr/portage"
PORTDIR_OVERLAY="/usr/local/portage/layman/xmw /usr/local/portage/layman/init6 /usr/local/portage/layman/poly-c /usr/local/portage /usr/portage" |
when "emerge --info |grep PORTDIR" is run.
Running "emerge -pv mesa" gives me
| Code: | | [ebuild R ~] media-libs/mesa-10.1.0 |
Notice it comes from ::gentoo not ::init6
So the highest number wins in PORTAGE_OVERLAY, first one listed is 1, second one is 2, etc.
Sorry Telemin, I told you wrong above. This is the correct way to do it.
Edit to add: In my case I want it to look at my local portage 1st, then gentoo, then overlays so I have PORTDIR_OVERLAY like this
| Code: | | PORTDIR_OVERLAY="${PORTDIR_OVERLAY} ${PORTDIR} /usr/local/portage" |

Anon-E-moose, nice explanation! It should be this way in the wiki (I don't understand very well the way it's written on the wiki).

One more thing, like I said, I want it to look at my local portage 1st, then gentoo, then overlays
But if you want something from init6 such as mesa and regular portage is overriding it
you can override that with "emerge <whatever flags> mesa::init6"
Edit to add: This is how mine is set right now (from make.conf)
| Code: | source /usr/local/portage/layman/make.conf
PORTDIR=/usr/portage
PORTDIR_OVERLAY="${PORTDIR_OVERLAY} ${PORTDIR} /usr/local/portage" |
which yields this
| Code: | | PORTDIR_OVERLAY="/usr/local/portage/layman/xmw /usr/local/portage/layman/init6 /usr/local/portage/layman/poly-c /usr/portage /usr/local/portage" |
Highest priority is end of line working backwards.
One could also comment out the source command, and set PORTDIR_OVERLAY directly with whatever order one wants.
Note: If you add new overlays then you would need to hand edit PORTDIR_OVERLAY to add it. But it gives fine grained control.
