I don't think I've synched it after that (but I'm too lazy to look up the `find' info page to check properly). Is that any good? Yeah, that would be fantastic, thanks, Alan. Could you possibly tar it up and stick it somewhere for me to download? As a matter of interest, how, exactly, are you going to use the old portage? Is it a matter of updating in two moderate chunks rather than everything at once? Yes, basically. If I were to `emerge --sync` today and try to `emerge -u world` I would get loads of blockers where the current version of package X depends on package Y version 2.15. But only version 1.1 of package Y is installed, and the latest version depends on some much newer version of package Z. And the latest version of package Z depends upon something else… That's the easy part. What tends to happen as you dig through these is that you'll get a bunch of compile time errors because of package version incompatibilities, ones that are undocumented or not listed as version dependencies because no-one ever tried the latest version of package X with a 3 year old version of library Y before. And I think you also tend to get middle ground problems where one package needs a version of another that is higher than 1.1 but lower than 2.5 and neither version are in the tree any more. I've only done this a couple of times, and never with such a large leap as would be required for this system. But each time I really had to play it by ear, got really ugly compile-time package failures and had to sort them out by digging around in the Portage CVS attic. It's not really difficult (for an experienced Gentoo admin) it's just a royal pain, and pretty frustrating (as you solve one problem, only to run into another). And it seemed like trying to be too aggressive in the resolution of the problems made them worse. So, yes, what I would ideally like to do is update this 6 months at a time. I can find a Portage tree that is 6 months newer than the currently installed system, then all the packages in the new tree will probably have been tested (documented deps c, clean upgrade path) with the older ones on the system - the versions would have been tested by the Gentoo devs contemporaneously when they were originally in the Portage tree together. When the system is working with the 6 months newer packages, `emerge -e world` (to get *everything* up to date with that time snapshot) and then do the same for a tree another 6 months newer. This all sounds very time consuming. But updating a typical Gentoo system that is 6 months old doesn't usually present too many problems - the time consuming part is the compilation, which can be left running overnight. Stroller.

The thing is that I'm one of the rare people who never upgraded their PS3 to the first firmware upgrade (3.15?) which removed Linux capabilities. So I am still legal by Sony's definition of the term (much as I disagree with these policies), and would prefer to stay this way. AIUI there are a bunch of custom firmwares about, either for installing cool media players (or piracy tools) under GamesOS, and some more custom firmwares aimed at making Linux more powerful (by removing the hypervisor restrictions upon it). But I really don't want to install these in case I decide at some point in the future that I want to install the latest official Sony firmware and Sony detects I've been running pirate games and bans the console from the gaming network. Really, there's no need to update the PS3's firmware because it does everything I need at the moment. The firmware version has no bearing to the existing Linux installation. Hope this makes sense.

Assuming your / partition isn't tiny I've never seen removing packages or changing use flags make enough of a difference though there are a couple of exceptions. Chances are you've got old data rather than binaries somewhere that's causing the space problem. /usr/src/linux-* Each new revisions of the kernel that you install drops a /usr/src/linux-$version directory. These are pretty good size and you should remove the packages of any kernels you not using. You may also need to manually remove the dirs as well after the packages have been removed. /var/lib/mysql It's usually not the databases that use space on a home system, but the binary logs. Add these two lines under the mysqld portion of your /etc/mysql/my.cnf and restart Mysql. You may need to purge bin logs as well though Mysql should clean things up when you restart it. [mysqld] expire_logs_days = 10 max_binlog_size = 100M /root/ /tmp/ / Lot's of people have the bad habit of leaving dumps, tars or other files in these dirs. Check them out. Lastly a df -h and a sudo du -m --max-depth=1 / would go a long way towards pointing to where the problems are. kashani

Re: [gentoo-user] Re: Problem with xf86-video-ati nvidia-drivers
I was thinking about this. The digital HDMI signal must be converted into an analog signal at some point if it's being represented as light on a TV screen. Electrical interference generated by the computer and traveling up the HDMI wire should have its chance to affect things (i.e. create weird shadows) at that point, right? Not with DFPs. Those work digital even internally. I assume of course that his HDMI TV *is* a DFP. But at some point the 1s and 0s must be converted to some sort of an analog signal if only right behind the diode. A diode must be presented with a signal in some sort of analog form in order to illuminate, right? Digital is just a figment of our imagination after all. Sure, but that couldn't introduce ghosting as shown in the picture. Ghosting represents the image being offset in its intended raster coordinates. By the time a diode is turned on or off, the decision if which diode a signal goes to has already been made. True, but *is* that D/A conversion made right behind each diode? - Grant

Well this is an unfortunate way to learn how find works. A better way would be: $ man find Basically find works of a chain of selection criteria. It crawls all the files/dirs and when one item in the chain is true for the criteria, it checks for the other. For example $ find /path -type f -name blah -print Crawls /path, for each file/dir it checks if it is a regular file (-type f), if that is true, it checks if it's name is blah, if that is true, it prints the name (blah). Therefore, $ find /path -delete -type f -name Crawls path, then checks -delete.. but wait, -delete evaluates to true if removal succeeded (find(1)), so it deletes the file, then checks to see if it is a regular file, then if that is true then it checks the name... but all that doesn't matter because your files are deleted. You should never put -delete at the beginning of a chain and, arguably, you shouldn't use -delete at all. It even says in the man page: Warnings: Don't forget that the find command line is evaluated as an expression, so putting -delete first will make find try to delete everything below the starting points you specified. When testing a find command line that you later intend to use with -delete, you should explicitly specify -depth in order to avoid later surprises.

If you're monitoring teenagers or employees for inappropriate behaviour you might be happy with a screen shot every 1 - 5 minutes, so you could just use some kind framebuffer grabber (media-gfx/fbgrab?) and a cronjob. You could stitch those together daily into a speeded up video for easier review (you might be able to do this with mencoder, just by slowing the capture framerate down to once every 60 - 300 seconds) or compile the whole lot into a page of HTML to scroll through.
