[gentoo-user] What to expect from emerge --newuse --emptytree world re: etc-update

[gentoo-user] What to expect from emerge --newuse --emptytree world re: etc-update

[Dave Nebinger]

I'm getting ready to dive into the apache2 install on my server.
In preparation for this I needed things I wasn't using before like
IMAP (see thread on web mail systems), MySQL, and ldap.

Being the good little gentoo boy I updated my USE flags to include
these and other settings that I plan to use but didn't have in before.

And since my USE flags changed, I'm in the middle of doing the
"emerge --newuse --emptytree world" (it's actually going quite well;
out of 417 packages, only scotty failed due to some sandbox violations
that I'm not worried about right now).

I've got about 10 hours left on the recompiles (estimated), so tomorrow
morning the next step will be to handle any /etc updates.

But that's got me wondering - am I going to be looking at hundreds
of /etc updates?

If I am, I'm certain I don't need them as my existing configs are
all working fine.

So if I am looking at hundreds of /etc updates that I don't really
want to have to wade through, what would be the easiest way to purge
them all?

Thanks in advance,

Dave

why the emptyworld?
when you change flags, --newuse world is enough.

hum, that seems like a bit of overkill. wouldn't emerge --newuse world
have sufficed? If you only added imap, mysql, and ldap, there should
only be fewer than 150 packages out of 417 that needs to be
recompiled.

something like that, yes. 

BUT, if you are like me and do not modify most of the configuration
files, LOTS of those files in /etc will get handled automatically by
etc-update... you only need worry about those files you have changed
from the defaults.

My "find" syntax is a bit rusty, but I think running the following as
root might do it: (you can sub -f for -i if you are real adventurous)

find /etc -name "._cfg00*" -exec /bin/rm -i {};

Well there were actually quite more use flags than that.  To prep for
apache I added the jpeg, png, xml & xst, php and a bunch of other
related flags.  Some of them are probably overkill, but it seemed to be
a significant enough change to the USE flags that I thought may touch on
more of the installed components than such a short list.

The --emptytree as well might be overkill, don't know for sure.  I
thought it would be the safer option to ensure that dependencies, etc.,
would be covered.  Either way it is too late now as the recompiling is
almost finished.

I tend to get into many of the configuration files for one reason or
another adding or removing options that are specific for my site (and I
guess I'm a control freak ;-)

So on the majority I would be looking at many updates.

That's the route I'm probably going to take.  Thanks Willie!
