[gentoo-dev] a virtual advantage ?

[gentoo-dev] a virtual advantage ?

[Philip Webb]

Yesterday, I upgraded 'xorg-drivers' to the latest stable 1.10
& then found upon rebooting that X failed to recognise the keyboard.
Yes, it's happened before & I was not surprised:
I had to switch the machine off, reboot, login as root
-- experience long ago made me avoid booting directly into a GUI -- 
& recompile 'xf86-input-evdev', after which everything returned to normal.
Yes, there's a warning after the new 'xorg-drivers' has been installed,
but I wasn't sure exactly which pkg(s) needed remerging, so took the chance.

My point is that it looks -- to a naive user -- like a good opportunity
for another 'virtual', which wb satisfied by Evdev or equivalent.
This would avoid the problem when busy users miss the warning notice
(see a current users' thread).

Perhaps this would in turn need an extension of the 'virtual' concept,
to require rebuilding of the relevant pkg to satisfy the main emerge.
There is another thread today re 'revdep-rebuild' + Python + Perl,
which seems to cover a bit of the same ground.

Thanks as always to the devs for their conscientious unpaid efforts.

Hmm?  AFAIK, it gives you an actual command that will emerge all 
x11-drivers/*.  So can you not be sure which pkgs need remerging?

portage 2.2 has a nice set for that called @x11-module-rebuild :)

He doesn't use portage 2.2 so he would have to settle for "qlist -I -C 
x11-drivers/" instead.  I think his point is, it's easy to miss those 
messages and not know you need to rebuild things.  It would be nice if 
portage did that for him.  You know, automagically.  ;-)

Maybe one option (until portage-2.2 is ready) would be to move the
informative message to pkg_pretend, that way the message would be shown
just after starting "emerge -uDN world" allowing user to interrupt it
and run "emerge -uDN world && emerge -1 $(qlist -I -C x11-drivers/)"
directly.

Yes, but it's not precise enough :

  root:534 xorg-server> qlist -I -C x11-drivers/
    x11-drivers/nvidia-drivers
    x11-drivers/xf86-input-evdev
    x11-drivers/xf86-video-nv
    x11-drivers/xf86-video-vesa

The only one I needed to remerge is the 2nd in the list.

But you don't know that for sure, and neither can portage (driver ABI 
changes are not something portage can track.)  The only sure thing is to 
emerge them all.
