I noticed this behavior the other day.  I just didn't have a chance to
look into it at the time then forgot about it.  When I saw your post, it
reminded me that I ran into the same issue.  It was time to look into it
and see if it made that difference.  Now we know. 

With that option, I don't know if the module-rebuild set would work or
not.  I suspect it may result in the same.  To be honest, I don't use it
because the only one there is for me is nvidia-drivers. 

Glad to help.  It's not like I don't get help from this list on
occasion.  ;-)

Hi Dale,

thanks for the info and help!

Just a few seconds before I found the reason for all that reasons :)

It seems that -- exactly as you said -- this option prevents
reemergeing of the same packages again.

If you want to force an update "gnu/foobar" (for example) you need to
submit

emerge --selective=n gnu/foobar

which temporarily overwrites --changed-deps.

By the way: I appreciate helps like yours much more than just pointing
to the obvious docs. ;)

Cheers!

I tested this here.  Like you, I added --changed-deps to make.conf with
the plan to remove it later.  It seems when that is put there, it
doesn't emerge like it usually would.  It acts like it is looking for a
update not a re-emerge of the same version.  However, when I removed
that option, it works as it should.  I don't know why it does that but
that is what it is doing.  So, remove --changed-deps and try again.  It
should work.

Is that a bug?  Don't know.  It may be that it is intentional but maybe
it shouldn't be. 

Hope that helps.

[gentoo-user] Forced rebuild of a package...how?

[tuxic]

Hi,

after installing linux-4.15.1 (downloaded from kernel.org) I want to
reinstall (beside others) nvidia drivers.

Emerge told me:
|>emerge nvidia-drivers
|Calculating dependencies... done!
|>>> Jobs: 0 of 0 complete   Load avg: 1.05, 0.65, 
0.34
|>>> Auto-cleaning packages...

That is valid for the previous installed kernel...but not for the one 

This was updated just before
Sun Feb  4 04:21:46 2018 <<< sys-apps/portage-2.3.23
Sun Feb  4 04:21:51 2018 >>> sys-apps/portage-2.3.24

My make.conf has this options:
EMERGE_DEFAULT_OPTS="--jobs=4 --load-average=4 --changed-deps-report=n 
--changed-deps"


Thanks for any help in advance!

1. do another backup
2. take your last good binary package and unpack it in the root
directory - it is an "image" of that package as it sits in the file system.
3. rebuild that version of glibc by overiding emerge - comment out "die
"aborting to save your system" in /usr/portage/eclass/toolchain-glibc.eclass

I have done this a couple of times with gcc (when manual deletes have
gone rogue) but it should work with glibc as you have not recompiled any
new packages.

Have you tried just plain "su" ?  Can you do "sudo bash" ?  That might  
be an easier (temporary) workaround than ssh.


See if "ls -al" in /root and in /etc show some file with strange

I can still get to root by `ssh root@localhost' having set up

For the history of English, I recommend Otto Jespersen
'Growth & Structure of the English Language' ;
the 1st edition was 1905 & I believe it's still in print
(I have the 9th edition from 1938, printed in Germany by Teubner).
Among many other matters, he mentions that 'that' was
the original relative pronoun, while 'which' came only later.

Ah, sorry, I misread that (in your case it wouldn't make any sense, either).  
Although in that case, shouldn't normal rsync do what you want?  It won't 
update files that haven't changed since the backup (determined by default by 
comparing file size and mtime, see rsync(1)).

If you can access the backups like a normal file system, then using  
rsync with

the --update option looks to me like what you want:

"-u, --updateskip files that are newer on the  
receiver".




High Marc,
I think I need the opposite :
  only update files which are newer on the receiver

Cow, Sheep, ... I think there are a lot of words in common.

Not that I have any personal experience, but I've come across several
reports that British soldiers stationed in West Germany after the war
had no difficulty talking with Germans who spoke Platt-Deutsch (or
however that is spelt).

Modern English is an evolved mess of Norman French and Anglo-Saxon, and
seeing as the Normans (Norse-Men) were really Vikings not Franks ...

That makes sense.  So, if worse comes to worse, downgrade, then emerge
-e world if unsure what all has been updated since.  If, using qlop or
friends, you can figure what was done since the upgrade, emerge those to
make sure the linking is correct.  At least that is a option that should
be doable.  That's better than thinking you can't downgrade for any
reason, period. 

I wonder, is this sort of info on Gentoo's wiki?  If not, shouldn't it
be?  I've always read that downgrading is a bad idea and strongly
discouraged but if one runs unstable on a regular basis or just hits
that random corner case bug, one may run into this even if one doesn't
have the experience to know how to put the broken pieces back together
again. 

Thanks for the info.  At least there is a option, even if it might get
interesting.  ;-)

Thanks for the hearty laughs. It reminded me of a joke in which a priest’s
son and his friends find a dead bird. Now the kid often observed his daddy
at work, and so felt the obligation to give the bird a proper burial. He
ended with:
“… in the name of the father, the son, and into the hole he goes.”

I be he would have joined sentences with commas too, though I never saw 
anything of his written.

I believe those languages, the ones descended from Latin, are called romance 
languages, and yes, they do have common features such as pronunciation of 
vowels.

Having so many words derived via French from Latin, English is also a 
romance language to some extent. I know it's officially classed as a 
Germanic language, but I can't see why. There seems to be no Teutonic 
influence to speak of. Few words in common, very different sentence 
structure, ...

[gentoo-user] Re: Heads Up - glibc-2.27 breaks my system

While on this topic, I have a question about glibc.  I have it set in
make.conf to save the binary packages.  Generally I use it when I need
to go back shortly after a upgrade, usually Firefox or something.
However, this package is different since going back a version isn't a
good idea.  My question tho, what if one does go back a version using
those saved binary packages?  Has anyone ever did it and it work or did
it and it fail miserably?


It is perfectly fine to downgrade glibc if you didn't emerge anything 
that compiled binaries.


If you did, you can still downgrade, but then you need to rebuild the 
packages that you emerged since the glibc upgrade. qlop is your friend 
here; it lets you find out the dates on which you emerged packages.


This whole thing is not actually special to glibc. Other libraries work 
in a similar manner. You can't just link other software against a new 
version of the library, then remove the library and replace it with an 
older one. It might result in breakage. But glibc is used by almost 
everything, it's not "just a library", it is *the* library, and so it 
has a special protection to prevent a downgrade. You can bypass that 
protection and downgrade anyway, but then you need to know what you're 
doing and how to restore your system correctly. If any sys-devel 
packages are affected, you might not be able to do it. If only end-user 
packages are affected which are not used during an emerge, then it's 
quite safe to downgrade.

No. You get that with GCC 7.3 already, which is in portage now.



However, improvements to these mitigations will from now on happen for
kernel 4.16 first and backported later. 4.16 for example got mitigations
for ARM. It's how kernel upstream works; new stuff is done in the
current development version, and backported later to still supported
versions.


Spectre_v1 still shown as vulnerable on both Intel and AMD.  Is there a fix
planned for this?


I don't know, but it would be surprising if there wasn't.
