An emerge wrapper for breaking emerges into chunks

hielvc · Posted: Wed Feb 14, 2007 5:09 pm Post subject:

Hi, yeah my cox service was mostly down last week and no Cox wasnt showing any work ordes for my area but my son who works nights keep seeing the Cox trucks, the big ones, that are used when they run new or additional cable. :twisted:

But today 2-14-07 Ill be going down until some time this evening probably.

I'm upgrading from a Sempron 2800 754 (32bit) to a Pentium 4 D 805 ( dual core). This would be no bigee but
Im also going to try software raid with 2 80Gig drives which includes the one which has my new pentium system . The 60Gig, in the Sempron, is bacisly full so Ill save my /var/log/emerge.log /var/lib/portage/world /var/db/pkg and my packages from the 80G to a 18G. The other wrinkle is my PWR supply which is only 300W which works fine with one or 2 HD, a dvd and a floppy (for work). I wondering though if it will handel 3 or 4 HD?

super-lupo I didnt install plaudis but read through some of the support thread and emwrap.sh wont currently work with it. It needs a script though if for no other reason than to have short options instead of those dang long ones it seems to use.

EDIT Writting this helped to clear my head and Im off to steal, hum borrow, a dvd-w from my son who borrowed about 60 cdw's from me. Then Ill just use a install cd to boot and rebuild the dually.

hoyanf try running the "bash -x emwrap.sh " If the output is to long then "bash -x emwrap.sh >output.lst" and open up "less output.lst"

Ill try to help but my Mother had a massive stroke is unresponcive. I found her yesterday afternoon. Today my brotherand I are going to start to set things in order. The Doctor is giving her at most a month.

Again dol-sen thanks for your help.

Hey Hiel,

I began writing a gentoo installation guide a few days ago on gentoo-wiki.com, it also uses your emerge wrapper. Just thought you might like to take a look!

Keep up the good work!

Sounds interesting! I'll give it a read as soon as I find the time to

But anyway, what I did was actually just copying hiel's summary of steps for upgrading from page 1 into the wiki.

Furthermore, how would you suggest to fully update a box were, say, new ebuilds are available for tc, system and world? Like this?

hielvc · Posted: Wed Feb 28, 2007 6:44 pm Post subject:

Late but heres my 2 cents. The 3 main ideas behind me writing this were to build the TC first, save time and try to build against upto date libaries once. Things have changed, we now have a fine tool called revdep-reuild and 2 excellent guides, Changing the CHOST variable and Gentoo GCC Upgrade Guide.

I still perfer to build any TC update first and there are times when you have to build it first or "emerge system -e" three times, to get a clean TC, so emwrap.sh does it first.

As to rebuilding the system or world twice I have pointed out that I don't. With the TC built first I have never had a problem with building the system except for groff, which always builds once the system is through updating. Its been at least a year and half or two since I did. For the system the libs dependencies arent as deep? complex? multilevel? The most common probablem is where CHOST was changed or the gcc enviroment has probs. These are better taken care, and in some cases the only way to fix, with the above guides and revdep-rebuild. The same goes for the world packages. Revdep-rebuild is usually quickerwith a far smaller list to rebuild.

Another reason why rebuilding twice isnt as important is that portage has improved in calculating DEPENDs and RDEPENDs.

So that said, depending on the chunk size you want to break "emerge world" into.

For --emptytree emerging

Moderato "-S" is the equivalent to " -se ". Its a hang over from when I first came up with world minus system. In its first form, emwrap.sh-3.0.5, you had to run

Hi again,

thanks for the explanation.

One more thought, though. What does the script when it sees slots? I noticed following: it's just rebuilding the first/earliest version of the ebuild.

I have installed, for example, dev-java/sun-jdk-1.4.2.13-r1, dev-java/sun-jdk-1.5.0.11, dev-java/sun-jdk-1.6.0-r1; BUT only dev-java/sun-jdk-1.4.2.13-r1 is to be rebuild. I really do see a problem here, because rebuilding only the first version is not a good deal since mostly the latest or at least both versions are used.

Anyways, did I do anything wrong? I'm at emwrap.sh -W and that's what the /tmp/emwrap/build file says.

Thanks in advantage.

I think I found another bug with your script.

When building just the tool chain, it says it will do:

curmudgeon I just logged in and saw your post. I either didnt get notified or I was over zealous in deleting email notification :?:

Ill look at it and get back to you.

i have no patience in reading/searching through the whole thread (perhaps this feature was requested before)
but one feature request from my side.

What I needed in case that the resume list is deleted on restart ( is for me the case because I have /tmp /var/tmp mounted in ramfs ) would be
a switch with that i can say skip packages until number ( e.g. 264 of 279 ) so that it resume at 264, heh?
whole number of packages is gathered via

Ho-hum... I've got the issue that emwrap.sh wants to rebuild the toolchain no matter what, even if it just finished rebuilding it. How's that possible?

Should I post emerge --info and friends?

Well, firstly what parameters/arguments are you passing to it?

red-wolf76 · Posted: Thu May 31, 2007 6:37 am Post subject:

You're right. Pure PEBCAK! I was passing -seb to the script, forcing it to always detect a linux-headers update. :oops:

emwrap is currently broken - doesn't execute gcc-config properly with gcc-config-1.4.0-r1

tekknokrat · Posted: Fri Aug 31, 2007 2:36 pm Post subject:

I switched my profile from desktop to hardened and now gcc-4.2 and glibc-2.5 wont emerge.
gcc because it is masked by hardened profile.

so I was trying to emerge my system with the old ones:

gentoo portage # gcc-config --list-profiles

[1] i686-pc-linux-gnu-3.3.6 *

and gcc- sys-libs/glibc-2.3.6-r5.

But glibc doesnt permit downgrading by sanity check.

Talk with the guys in #gentoo-hardened on freenode, from what I remember glibc 2.5 (?r4) should be fine but gcc will definitely have to be downgraded.
