Re: [gentoo-user] How can I move system to new disk?
2010/1/15 Jarry mr.ja...@gmail.com: Hi, I'm facing this problem: I want to exchange hard-drive in my computer for other, bigger one. I do not want to add new hard-drive somewhere on mount-point permanently, I just want to copy everything from the old drive to the new one and then get rid of the old one. And of course, I'd like to use my computer as before. What is the best (maybe I should ask for safest) way to acomplish this? First I thought about cp -a. But I'm not sure which directories I should skip (/proc, maybe some other like /dev?). And I do not know how cp handles links (if I first copy link and later target, where is the link pointing? to the original file or its copy?). Maybe dump/restore is better solution? Or something else? Jarry I've done it twice with the following method : http://www.faqs.org/docs/Linux-mini/Hard-Disk-Upgrade.html There are a few things to change : no more Lilo, ext2, IDE, diskettes these days But the check list is complete so you won't forget important points.

Alan McKinnon wrote: The only way to be sure of that is to write your own replacement for HAL. ;) That might not be a bad idea I never agreed with the implementation of hal. An abstract layer sounds good, but why must it abstract ALL hardware? Most software already knows what type of devices it is going to use, so that software should either do it's own abstraction, or a utility library should do it, but be limited to what devices it deals with. Most devices fall into one of two groups: storage and I/O. Auto-mounters do not care about your keyboard, whereas X needs to know about your monitor, card, keyboard, mouse. Why does hal try and abstract both? Seems silly to me. One could also argue that the developer's state of mind is reflected in the chosen method of configuration - xml files. This just defies all understanding. Apart from the fact that real-world xml is almost unreadable, the conditions that make xml useful are simply not present in hal... xml works well when you have system A talking to system B and neither A nor B (nor user C) know in advance exactly what the other is. They might not even know much about the data schema being used, so that metadata is in the xml. This is so completely not the case with hal on a local machine, that it defies description why the dev thought it might be useful. I can't argue with any of that, which is why I decided to quote it in full - it's worth repeating. It seems xml is the fashion with certain programmers.

But copying an in use filesystem is a bad idea, better to boot from a live CD and do the job there. If you want to minimise downtime, do the rsync on the working system then boot from the live CD and do it again. The second run should take seconds but will make sure your disk is consistent. Remember to use --delete on the second run. I did it this exact way when I bought a new HDD for my laptop last Christmas, because then I could still use my normal system instead of booting a LiveCD and waiting for the sync to finish (which could take half an hour). Copying 16GB from a laptop HDD to another one via USB is not that fast. Only before everything was done and I was ready to boot with the new HDD, I did another rsync with logged-out users on TTY1, which takes but a minute. IIRC I didn’t even boot a live CD. And even IF there were some flaws in the mirrored system, there’d be no harm done as I have the original still around to amend them. -- Gruß | Greetings | Qapla' Crayons can take you more places than starships.

You cannot totally separate the two areas, for example a keylogger may need access to both I/O and storage, so a central, separate resource used by all software is more in keeping with the Unix way than each program including its own implementation.

XML was very fashionable a few years ago, maybe this influenced the developer. Hell, I was even guilty of using it myself :( As an alternative to binary configuration files, XML is a step in the right direction, but it should not be used where users are expected to edit the files. In some ways, the worth or otherwise of HAL, from a user perspective, has been largely obscured by the difficulty in reading, let alone editing, its configuration files. -- Neil Bothwick I am MODERATOR of BORG.

Re: [gentoo-user] Going ~x86?
Hi there! It's done! I'm at ~x86 now. The upgrade went quite smooth - had to resolve some blockers, and mask the new x.org 1.7 because it does not work at all with ati-drivers. **BUT:** After rebooting, I ran into a very nasty KDE4 bug. All authentication dialogs did not work. So I had no KDE wallet, no kmail, no kopete, no webmail... now this was annoying! Must be some strange side effect, I do not think anything of KDE itself had been updated. I spent quite some time trying to solve this. Without an existing ~/.kde4 directory, it worked, but all of my .kde4 backups (I have lots, I make one whenever I save the session, because this does not work sometimes) had the problem. So I searched for the file in ~/.kde4 that was responsible for it, and finally I found .kde4/share/config/kdeglobals. And, more prrecisely, this setting: [Passwords] EchoMode=ThreeStars I commented this out, and all is working again. Yes, I will file a bug report upstream. This kind of bug is what made me not switch to KDE for a long time. The possibility of suddenly having a little problem which makes the whole KDE thing unusable until solved. Wonko
[gentoo-user] How to determine if a NIC is playing gigabit?
Hi there, Yesterday I reseated the network cable between my server cupboard and my desk, and it now lights up on the switch by my desk as gigabit. But a file-transfer today is slower than I might have hoped. I'm not ruling out the cable, because it's pretty beat up (but the switch *is* lighting up as 1000), but how do I determine, please, that the Linux server at the other end is recognising the NIC and negotiating as gigabit speeds? The hard-drives on the server are using an older PCI SATA card, and the NIC is also PCI. But I would have expected it to be a bit faster than 100Mbps. Any estimates over what kind of speed I should be seeing for large file-transfers over Samba? Wildly ball-park is fine - I wouldn't expect a 10x speed increase, but maybe 2x or 3x - 4x would be great! I'll be testing between my Macs (both on the desktop switch, ruling out both the Linux box and the suspicious cable) later today, I'd just like some ideas of where I should be starting from. Right now I'm seeing 10 gigs of .mp4 files (1gb - 2gb per video file) taking about an hour - that's about what I'd expect from old 100Mbps networking, not this shiny new stuff. I'm not seeing any difference commenting uncommenting aio read size = 1, aio write size = 1 (separate lines) from /etc/samba/smb.conf and then running `/etc/init.d/samba reload`, but maybe I shouldn't expect that to make any difference on an existing transfer. I just don't want to interfere with this right now - I just want to copy as much as possible on to my laptop before I go out, and I'll take a look at this performance issue when I get home. Thanks in advance for any suggestions or pointers, Stroller.

[gentoo-user] tvtime overscan not centered
I recently got my old TV tuner card out of the closed and decided to set it up. The kernel's v4l2 drivers support my card and it works just fine with tvtime. However, tvtime's overscan setting doesn't center the image correctly; when increasing the overscan value (to get rid of some random crap at the edges of the image with some stations), the image doesn't zoom evenly in all directions but rather only to the bottom and right. Is this a bug? Anyway to fix this?

Re: [gentoo-user] Can you rewrite this 1996 qfile command?
I've hit a bug that won't let me start an xfce4 session. I think it was caused by upgrading glibc, and it is pretty well described in this nearly 4-year-old bug: http://bugs.gentoo.org/125909 The solution is presented as: qlist -o $(qlist -ICv) | scanelf -Bs__guard -qf - -F%F#s | xargs qfile but I get: qlist: invalid option -- 'l' qlist: invalid option -- '[' Removing the -l fixes the first invalid option, but I don't know how to fix the second. Does anyone know how to rewrite this command so it will work? I can't see how you can get those errors, unless you have a broken qlist that is outputing something dodgy from the qlist -ICv If it persists, copy-paste your input and the output from your terminal into a mail. Or run qlist -o $(qlist -ICv) | less and examine that closely for errors I was making a transcription error before, but after correcting it, it still doesn't work: # qlist -o $(qlist -ICv) | scanelf -Bs__guard -qf - -F%F#s | xargs qfile Usage: qfile opts filename : list all pkgs owning files Options: -[ef:m:oRx:vqChV] -e, --exact * Exact match -f, --from arg * Read arguments from file arg (- for stdin) -m, --max-args arg * Treat from file arguments by groups of arg (defaults to 5000) -o, --orphans * List orphan files -R, --root-prefix * Assume arguments are already prefixed by $ROOT -x, --exclude arg * Don't look in package arg -v, --verbose * Make a lot of noise -q, --quiet * Tighter output; suppress warnings -C, --nocolor * Don't output color -h, --help * Print this help and exit -V, --version * Print version and exit Does anyone know what might be wrong? - Grant I think the problem above is that -I isn't a current option of qfile, but removing it produces the error I originally posted about: qlist: invalid option -- '[' - Grant

XML is handy for nested configuration, where various options apply to specific subsets of other configuration items. I could count on one hand the number of times that has actually been the case for any real world program I have worked on. If you use key:value lines, the parsing is so simple that you don't need any outside package, but you still have to clean up lines to remove comments, skip empty lines, and merge consecutive lines -- a few extra lines of code, not enough to even put into a library, let alone turn into a full-blown package. But parsing XML is too much work to reinvent each time, so people write complete parsing packages for it. From the purely programming point of view, those packages are simpler to use than rolling your own for 5 lines, and thus they use them everywhere.

XML allows you to generate complex, structured, hierarchical data that can be read, changed, and stored by well-tested third party libraries that don't need to know anything about the contents or meaning of your configuration data beforehand. This means I, as a developer, don't need to write any code to read and parse configurations, validate the syntax or structure (only the content), or persist it back out. In simpler terms: less time spent on the configuration parser, more time spent being productive. If there was a less-verbose alternative that was as easy to implement, with known stable parsing libraries, that had the same expressiveness as XML, I'd probably use that instead. But when you're talking about data that goes beyond a simple list of name/value pairs, anything attempt to stream it to a flat-file format is going to result in something that is either 1) redundant, or 2) hard to read. I'd go with 2 over 1 any day. In my opinion, if the worst thing you can come up with to complain about is they used XML for their configuration files, then I'd say that software is in pretty good shape. On the other hand, even I can see that HAL has plenty of problems (besides its XML configuration). The fact that it completely fails to work for you being a good example :) --Mike

Re: [gentoo-user] How to determine if a NIC is playing gigabit?
One more thing. The file transfer speed is min(max(HDD),max(NIC),max(others)) so it will depend on your HDD, your network and other reasons. I find out that using sftp command seem to be faster than NFS or Samba. Could you try sftp and check if it is faster or not? Then check the dmesg as well as network cables to see if there is any problem.

Thanks in advance for any suggestions or pointers, Stroller. In all likelihood, its your hard disk slowing down the network transfer, and not the cabling. Generally speaking, if the hardware says gigabit, than you've got gigabit.

Most parts are on order but one big change these days is the motherboards I want to purchase no longer support EIDE/ATAPI interfaces so I'll have to get a new CD-R/DVD-R drive to get the OS loaded and for writing mostly audio discs using cdda2wav/cdrecord. While I understand firmware is often a problem on these drives I'm wondering what drive manufacturers folks would recommend these days as having the best results with cdrecord? I have a cheap Sony Optiarc (formerly NEC?) and it has worked fine for me for ripping and burning audio CDs, DVD+/-R (single and dual layer). It cost around $25 USD. I don't know if it is better or worse than any other brand but it seems to work for me anyway. I just ordered an OptiArc 7240S from NewEgg this morning on a similar recommendation from the cdrtools list. Just curious - have you attempted any firmware upgrades from within Linux? Have you tried (or do you know about) the Liggy and Dee firmware? I've got AW-G170S and cannot remember if I've done a firmware update on it. I think Sony only release a Windows-based firmware installer but I'm not sure how the third-party ones work. I have read about the modified firmwares to change burn strategy, enable bitsetting (make a DVD-R look like a DVD-ROM to fool devices that refuse to play burned discs) etc but I haven't personally had a need to use it. I don't expect I will either. I was just curious as to your experience if you had. The drive is on order and hopefully new parts get here Wednesday or Thursday so hopefully I'll be running Gentoo on my new i5-661 by the weekend. Thanks for your inputs. cheers, Mark

Dale's experiences highlight a very important and very fundamental rule of desktop system design: As a developer you must completely and totally guarantee to the full limit of what is feasible, that the user will always have a usable keyboard, mouse and display after the desktop has launched. You can fallback to VGA resolution and the most basic keyboard layout possible if you need to, but you must give the user something and never leave them stranded. Anything else is just an epic fail. Magic SysRq falls so far short of this that it's not even worth contemplating. It's useful for mega-power users and kernel devs doing really way out things, but for normal users it might as well be invisible. Sure, it's documented in /usr/src/linux/Documentation/sysrq.txt. Well now, I offer two comments: I doubt that kernel docs are even installed on most user-centric distros, and anyone want to present an argument why the location of that file and it's contents might be construed as being self-evident and/or obvious? -- alan dot mckinnon at gmail dot com

Well now, I offer two comments: I doubt that kernel docs are even installed on most user-centric distros, and anyone want to present an argument why the location of that file and it's contents might be construed as being self-evident and/or obvious? I do remember when I was using Mandrake, the kernel sources wasn't even installed. I don't know if that option was even enabled in the kernel. With Mandrake, they just enabled modules for everything. When this happened to me, just being able to do a ctrl al backspace would have been good. I did try it but it didn't work either. That would at least be a good rescue in case of failure. Dale :-) :-)

Re: [gentoo-user] [OT] - What SATA CD-R/DVD-R drive manufacturer to buy?

It cost around $25 USD. I don't know if it is better or worse than any other brand but it seems to work for me anyway. I've got a couple of these, one SATA one PATA, the SATA one works very well but the PATA one is slower at ripping discs. While NEC is not bad, my current NEC drive does not read hidden audio tracks (like e.g. found on 13 Die Ärtzte). The answer can only be: It depends... Jörg Thanks Joerg. I sort of knew that would be the answer. Since I really needed something to build the machine and it isn't going to get much cheaper than $25 for an Optiarc I just ent ahead and got one. We'll see how it works. Is there any way to know ahead of time which drives will read the hidden audio track? Sort of related is that what about multimedia CDs - 8 tracks of audio and then a multimedia video. Any way to copy those with these drives? What's your opinion in the Libby and Dee firmware and/or flashing that firmware or Optiarc firmware updates using the binflash app? I'm in no hurry to do any of that but figured I'd learn a bit about it in the next week. Thanks, Mark

I can see Lenovo's point: there's probably less than 10,000 people in the whole world that ever used that key in the last 12 months and all of them are very au fait with Linux Yuck - really? Not even as an unlabeled Alt function of a Print Screen button? Sounds like a new kernel patch needs to be introduced, which allows you to select an alternative to the SysRq key for the magic commands... sigh Stupid HW manufacturers... To me, this sounds like rationalisation - in the make more efficient by reorganizing it in such a way as to dispense with unnecessary personnel or equipment sense - on behalf of hardware manufacturers. I would hate to do away with the numeric keypad myself, but at the same time I have to question how often I use it. When I look at the whole keyboard it seems crazy to have 102 or 105 keys in order to type 26 letters, 10 numbers and some punctuation. The function keys of regular keyboards are never used by the majority of people, and it has been this way for over a decade. Yet new keyboards require them because IBM keyboards had them in the 1980s. The authors of window managers map the close window shortcut to alt- F4 because the F4 key is there and is sure to be unused by anything else, but this function could easily be moved elsewhere if we got rid of the extra keyboard clutter.

XML allows you to generate complex, structured, hierarchical data that can be read, changed, and stored by well-tested third party libraries that don't need to know anything about the contents or meaning of your configuration data beforehand. This means I, as a developer, don't need to write any code to read and parse configurations, validate the syntax or structure (only the content), or persist it back out. In simpler terms: less time spent on the configuration parser, more time spent being productive. ... Your post makes sense until you realise that the use of XML in a configuration designed to be changed by the user renders the package virtually unusable. Given a choice between me as a developer struggling with a config parser versus vast swathes of users dumping the package because of the same parser, I'd say it's me that has to work harder, not my users. It pains me to be making another I use a Mac post here today, but since I do so, I don't really see the pain. I double click on an XML configuration file, and a GUI editor opens, a program designed specifically for editing such files. I can create new entries, child-objects of a configuration option, or I can just double- click on the entry's value and change it. Strings, numbers booleans are clearly marked, so that I can't break my configuration file by entering the wrong kind of data for a value. Of course, I use Gentoo on my headless servers, so I am glad that server software - Dovecot or Courier for IMAP, Apache, Samba - all have plain-text configuration files I can edit with vim (which I have been learning to utilise better recently). But even if these switched to XML, a curses XML editor could easily be written. As a novice programmer myself I was extremely glad to discover the Getopt::Long (and similar) modules when learning Perl recently. I have long written my scripts in Bash and parsed command-line parameters myself, with $1 and shift and whatnot, and I'm sure I've created some monstrosities with which it's easy for the user to foul things up just by entering parameters in an unexpected order. So I'd be very glad to hand off config script parsing to someone else - I write my software for myself, so I'm not sure I care how this affects users ;). Having said that, I'm a little surprised by Mike's assertion that there's no libraries for parsing text configuration files that are comparable with those for parsing XML. Stroller.
