[gentoo-user] Upgrade

[gentoo-user] Upgrade

[econti]

Hi everybody, this is my first post on the list.

Well, I'm running a 2.6.15-gentoo-r7 2006.0 on a AMD64 machine.

Now I'd like to make a world upgrade. I know that I should run the 
following commands:

emerge --sync
emerge --update --deep --newuse world
emerge --depclean
revdep-rebuild

A little question: how long does it take to complete the upgrade?
(sure, it depends on the installed software, but please give me an 
approximation)

Thank you

when was your last sync & update?

It's impossible, since it doesn't only depends on the installed
software. It also depends on many other factors:

1.- the time when you did the last update
2.- the number of packages that has updates, which is not always
    related to the number of packages you have installed, but to
    _what_ packages do you have installed. Some packages doesn't
    get updates too frequently, while others change a lot.
3.- external factors, like overlays

It just depends on _what_ needs to be updated.

I can give you a few hints, though. Most packages can compile in
a reasonable amount of time. Some specific packages will take
longer to compile. You will learn to identify them with the time.
For example, openoffice if probably the largest, and can take from
several hours up to days, depending on your hardware. Some kde
packages are big, like kmail. Qt or Gtk as intermediate things.
Glibc and gcc can take a lot of time, as xorg-server, for example.

Whe you are doing the update, you have to know a few things. On first
place, use this instead of your command above:

merge --update --deep --newuse --verbose --ask world

This will present you with a list of the packages that will be
updated, that way, you know how many packages are going to be
updated, but, more important, you will know _what_ packages will
be merged.

The depclean and revdep steps shouldn't be too time consuming
on a sane system. So, if you use them regularly, those steps
will not rob much of your time. The sync step depends on your
connection speed and the time since your last sync. It can take
a few minutes on a fast connection if your tree is up to date.
But it can take a day on a 56k modem if you tree is empty or
way too outdated.

You may want to add a -p behind that --depclean at first.  Just to make
sure it doesn't remove something you want to keep.  I usually even put a
-p on the end of revdep-rebuild just to be safe.  Mine always wants to
rebuild gcc when it doesn't need it.  It's a known "feature".  ;-)

As for the time it takes, it depends on what all packages have been
updated.  If it has been a while, then it will take a while to do them
all.  If there has been a major upgrade to gcc, then it will certainly
take a while.

Ouch. That's 2 years of stuff you need to update. Set aside 48 hours if 
you have gnome/kde or openoffice installed.

With that amount of updates, I would recommend you run 'emerge -e world' 
instead of 'emerge -uND world' - there aren't that many packages that 
have not changed so you might as well do everything in order.

You will also need to go to Gentoo docs and read up on the upgrade guide 
for gcc-3.3 to gcc-3.4, plus the xorg-6.8 to xorg-7.0 transistion. Both 
those upgrades happened in this timeframe and both bit many people in 
the rear end.

I'm pretty sure that it'll take less than a year... ;) just kidding...
The most it can take is the time of a complete new install, i guess.

After you "emerge --sync", run "emerge -NDpvu world" and post here the
output - the list of software your system wants to install/upgrade -
that should give us a better idea of what kind of an upgrade we're
dealing with here.

A quick question / addition to this. When I am finished with an update I
usually run etc-update. I was told last week that this has been phased
out and dispatch-conf is better to use. What is the difference?

It's not exactly related. In the future start a new thread instead and please 
don't top-post..

Whoever told you that is just wrong.

It worked very well, but I received a lot of messages like these:

!!! Error: couldn't get previous merge of hal; skipping...
!!! Error: couldn't get previous merge of hal-info; skipping...
!!! Error: couldn't get previous merge of gnome-mount; skipping...
!!! Error: couldn't get previous merge of nautilus-cd-burner; skipping...
!!! Error: couldn't get previous merge of gnome-media; skipping...
!!! Error: couldn't get previous merge of gnome-python-desktop; skipping...

What does it mean?

Exactly what it says. genlop couldn't find any previous emerges of the
packages in /var/log/emerge.log, so it was unable to estimate the time
for those packages.
