I was just reading a post there about this.  I was sort of curious as to
what others do and why.  I can see the point you are making tho. 
Keeping it in sync could be interesting. 

To add some info.  I enabled those and recompiled Seamonkey and Firefox
earlier today.  I had Seamonkey crash a couple times the other day and
thought I would try using it this way, see if it matters.  Firefox is
pretty stable tho.  The only gripe I have on it, memory usage and being
so dang slow to close.  I tell it to quit and it sits there for a
while.  Thing is, I have TONS of tabs.  It got so bad, I added that tab
grouping thingy to help sort them out a bit.  lol 

Thanks.

  A thread "Subject: [gentoo-user] palemoon again: USE=system-libs" is
asking the exact same question right now about Pale Moon (a Firefox
fork).  As a precautionary principle, I try to avoid system libs as much
as possible.  Using the internal version avoids ABI mis-matches (as in
"Windows DLL-hell") between the external library and the internal calls.

  System libs do work 99% of the time, but there can be problems if the
browser is updared and expects a newer library, or a library is updated
and changes ABI.  Gentoo ebuilds can specify dependancy version ranges,
but that may sometimes run into blockers if multiple apps want the same
library, but different versions.

[gentoo-user] Seamonkey/Firefox library USE flags

[Dale]

Howdy,

Looking to see how others do this.  I noticed that some "system" stuff
was disabled which I assume means Seamonkey and Firefox would then
compile their own versions of those things or something.  This is the
ones in question:

system-harfbuzz
system-icu
system-jpeg
system-libevent
system-libvpx
system-sqlite
system-cairo

Questions.  How do you set yours and why if you know why?  Which one is
most stable?  Any other advantages to having it one way or the other. 
Should some be on and others off? 

Thanks.

Some things to check for that:
You need the following tools installed:
- gcc
- make
- kernel sources
- kernel headers

And you need a symlink '/usr/src/linux' pointing to the sources.
The sources and headers need to be the same version as the running kernel.

These are not always available or set up correctly by default. Centos 7 needed 
some manual fixing when I installed in a VM it last week.

And now, with the 2.11 release, it's a squashed bug.

You need to mount the 'guest-additions-iso' in your VM. If you go to to the
device drop down you should see that option there. Then run the Linux
script in the CD, then reboot. You should get full screen.

[gentoo-user] Virtualbox oddities...

[Meino . Cramer]

Hi,

I am relatively new to the world of virtualboxing (NOT
"virtual boxing" ! :)
so my question may be stupid (tm)...

I installed Virtualbox  5,1,12. and installed a Linux
distro into a hard disk drive image. Finally the image
boots and now I have a "Linux in a (vitual) box" NICE!

But: The size of the inner window fame of virtualbox  is always smaller than
what the Linux inside thinks is the size of the monitor.

So I never get the whole desktop...

Is it possible to fix this without reinstalling the complete Linux?

Thanks a lot for any resizing help :) in advance!
Cheers
Meino

For OpenRC there's also restart_services[1]. I've grown to like it
better over checkrestart. Typically it restarts the services that need
restarting automatically, but you can define services as "critical" and
need an extra flag (-c) for restarting them. For a mail server, for
example, you might want to take extra care before restarting Postfix
after something has updated.

There is a genuine case for doing that. If you have already run it with
the list option, say from a script, it is safe to then run it with -r a
if you have changed nothing.
