Jackass! 2005.0 Support Group

Good call, Sith. :wink:

Although this isn't a problem with the Jackass! Toolkit per se, it is an artifact of the fact that the Jackass! Toolkit does use -O3 optimization. Occasionally, the user can expect to encounter an ebuild that will not compile with -O3 optimization, and when that happens, compiling with -O2 may be your only option.

Normally, when an ebuild maintainer will learn that their ebuild breaks under -O3, they will add a flag replacing statement to the ebuild so that it is built with -O2 rather than -O3. By doing this, the ebuild maintainer effectively fixes the problem with -O3 breaking their ebuild, without forcing you to de-optimize your entire system just because you want to use their ebuild.

In the case where -O3 breaks an ebuild, you need to notify the ebuild maintainer that their package is broken. If their package breaks with -O3 optimizations, then they need to do some flag filtering in their ebuild. This should definitely go into a bug report for that piece of software. Its a problem that needs to be fixed.

Optimally, the fix will entail solving the problem that leads to botched -O3 compilation, but if the ebuild maintainer can't fix the problem, many of them choose the easy way out and resort to flag filtration, replacing -O3 with -O2.

another point -- that RedHat Bugzilla report that you linked to mentions the fact that their problem was caused by insufficient swap space. -O3 optimizations require significantly more memory than -O2 optimizations. so if someone is running on a machine that has marginal memory or marginal swap, then they should consider adding more memory or more swap to their system. in such a situation its entirely possible that the problem is not with an ebuild, and that the problem is caused by an insufficient memory configuration to be using -O3 optimization. :idea:

I understand this is the support thread, but I had to find a place to voice my absolute satisfaction in Jackass. Working great on both a P4 and an old pentium. Very nice CFLAG selections too. Thanks for putting this together Bob and all others involved, it's a nice susbstitute for the tedious Stage 1/3 installation.

Hello, see mention of hielvc's or minderaser's update scripts but unable to find them, can someone point me right direction?

PS well done on great install method, do have problem with partition / not loading on boot but believe this not Jackass issue but a udev or misconfig on my part.

I dont know if this is the right place but here goes. How well will Jackass work starting from scratch with a hardened installation (specifically SELinux). I know I will have to use the hardened tool-chain. Is there any other conerns you can think of? Any chance of a Hardened-Jackass project popping up? Is it even worth it?

Additioanlly, any Jackass IRC channels pop up yet?

Thanks a lot Bob.I have done it! It's really thrilling to boot into the fake Jackass "Install CD".

.Your assertion that it is not a Jackass! specific problem gave me enough confidence to go ahead and do it correctly.In case someone is interested this is my Grub setting:
title Jackass!_Install_CD
root (hd0,6)
kernel /isolinux/gentoo root=/dev/ram0 init=/linuxrc looptype=squashfs loop=/livecd.squashfs udev nodevfs cdroot=/dev/hda7 initrd=/isolinux/gentoo.igz
Finally,I won't bother you on this forum if I have problems later on because this is an unsupported install method.

JACKASS! MIRRORS WANTED!

If anyone is interested in acting as a public distribution mirror for Jackass!, please contact me by PM.

basically, we need people with nice fat pipes that can host about 1.2 GB of files. our Jackass! Project home page will be the front end for the system, and a mirror page on our site will direct users to their choice of mirror.

there are all sorts of details that would need to be met to become a mirror, mostly related to technical aspects of file hosting, agreements not to post ads on the mirrors, making all of the files available to the public and not just to subscribers, etc.

please send me a PM if you're interested.

Bob_P:

is there a special reason that u build the kernel in the matter:

Sith_Happens · Posted: Wed May 18, 2005 1:55 pm Post subject:

As far as the make && make modules && make modules_install, I suppose you could say it's for debugging reasons. Personally, I use make && make modules_install, which does the same thing. As far as make install, I don't use it. Basically what it does is copies the bzImage and the System.map to your boot partition, and I belive gives them names based off of the source name (although it could just plop them there as bzImage and System.map). Of course you should mount your boot partition if you have one before running make install, otherwise it will plop them in the /boot on your root partition. I like to copy the files manually though, because I usually give them unique names based of their configuration. That and I just don't trust a machine to do a man's job. :wink:

yeah, cool like fonzy.

i think that everyone appreciated that it was said tongue-in-cheek.

regarding the win-win situation, yeah -- that's exactly why i've been doing it that way for so long. "make install" preserves everything that you need to preserve, and saves alot of idle typing. interestingly, i've spoken to some of the Gentoo kernel devs, and they never use "make install". needless to say, i was surprised to hear that!

Daring question here... Since everything is being rebuilt is it safe to change CHOST after installing the stage3 tarball? I know jackass has stages for most sub-archs but lets assume i want to use a generic x86 stage then upgrade to chost to i686.
