[gentoo-user] Portage internals : shadow root
Hi, when portage installs a package, it first installs it into some "shadow root". Then it records all files installed before it moves the files to the "real root". I have to do some installations on SUSE systems (which are not administered by me) and I'd like to imitate that procedure there. Can anybody tell me if it's not too complicated and if yes, how to achieve this (on a foreign system like SUSE). Many thanks for your help, Helmut.

Physical access allows them to change your password but not read it, so you'd know pretty soon if they'd been up to anything. If they really do need the root password, you have to give it to them, but that doesn't stop you changing it, and running a rootkit scan, as soon as they've finished with it. -- Neil Bothwick God said, "div D = rho, div B = 0, curl E = - @B/@t, curl H = J + @D/@t," and there was light. signature.asc Description: PGP signature

Remove all traces of yast and it's bastard brethren from the SuSE box. 2. Have three qualified sysadmins double check that you have indeed removed every last trace of it. 3.

Because it's a sneaky P.O.S. and goes to extraordinary lengths to nuke all your hard work done without it. And how you deal with file collisions is up to you. Yast really won't like you if you overwrite some config file with your own testing version. -- alan dot mckinnon at gmail dot com

Re: [gentoo-user] spamd segmentation fault and spamassassin will not emerge
Well, it was from perl 5.12 to 5.12.1 -- do I need to run perl-cleaner when doing that? I thought it was only for major versions, but if not, I can try that.

Simplify using PREFIX failed for me since many packages record the full path for configuration/data/help files etc. in the generated binaries or libraries. When moving such an application/library it will still search for those files in the build directory. I would image Portage uses some sort of chroot (then the pathes are identical) Furthermore, I cannot remove yast since I'm only a "guest" on such boxes. Normally I'd use a PREIFX=/usr/local/ but some application still install something into /etc/ or similar and I'd like to catch these cases. Helmut.

Alan does not know how to compile? ;-) He's been up to early. Have a look into the build.log and you find the answer: make -j3 DESTDIR=/home/prefix/gentoo/var/tmp/portage/sys-apps/texinfo-4.13/image/ install So it's not configure but make who takes the temporary install directory. PREFIX is indeed the final target. Al

FYI last night I upgraded to kernel 2.6.35.5 and everything seems to be working normally, so I guess whatever caused my problems has been solved. I still have long "waiting on uevents" at boot time, but I guess it's normal and was unrelated, and I usually only boot once every few months so it's not a big deal. :) Thanks, Paul

[gentoo-user] Anyone using fsarchiver to backup their Linux filesystems?
fsarchiver: http://www.fsarchiver.org/Main_Page I am using it to backup my Linux ext4 filesystems and Logical Volume Manager 2 (LVM2) logical volumes. Here is a very simple Linux shell script which I wrote to backup my /boot filesystem as well as the host operating system's volume group. #!/bin/sh DESTDIR=/media/usbharddisk FILENAME=22sep2010-wed.fsa BOOT=/dev/sda1 OPTIONS="-A -j 2" fsarchiver savefs $DESTDIR/$FILENAME $BOOT /dev/vg_fedora11_host/lv_home /dev/vg_fedora11_host/lv_root /dev/vg_fedora11_host/lv_var \ $OPTIONS Specifying the option "-A" allows me to do a live backup of the filesystems while they are mounted read-write. The option "-j2" allows me to use 2 compression threads (I am using Intel Pentium Dual Core E6300 processor @ 2800 MHz). -- Yours sincerely, Mr. Teo En Ming (Zhang Enming) 张恩鸣 Dip(Mechatronics) BEng(Hons)(Mechanical Engineering) Citizenship: Singapore Citizen/Singaporean Alma Maters: [1] Singapore Polytechnic (Graduated 1998) [2] National University of Singapore (Graduated 2006) Facebook account: Teo En Ming (Zhang Enming) Facebook link: http://www.facebook.com/profile.php?id=10750083982 Facebook photos: http://www.facebook.com/profile.php?id=10750083982#!/profile.php?id=10750083982&v=photos Facebook videos: http://www.facebook.com/profile.php?id=10750083982&v=app_2392950137 Mobile Phone (Starhub pre-paid): +65-8369-2618 Windows Live Messenger: teoenming-at-hotmail.com Location: Bedok Reservoir Road, Singapore ZIP: 470103 My Open Letter (Plea for Medical Help/Assistance) to World Leaders (Updated 28 August 2010):- http://lists.mcs.anl.gov/pipermail/mpich-discuss/2010-August/007811.html http://mythtv.org/pipermail/mythtv-users/2010-August/295952.html http://archives.gentoo.org/gentoo-user/msg_f6a341d9623fda17880159b137c07335.xml Photo of Mr. Teo En Ming (Zhang Enming) 张恩鸣 of Singapore #1: http://i53.tinypic.com/207tamp.jpg Photo of Mr. Teo En Ming (Zhang Enming) 张恩鸣 of Singapore #2: http://img713.imageshack.us/img713/7534/enmingteodscf2511.jpg Singapore Citizen Mr. Teo En Ming (Zhang Enming) sues God for being too busy and unresponsive.
