    [ Experiment ] Stripping Down KNOPPIX 7.4.2 DVD to Mimic KNOPPIX 7.2.0 CD

    Hi, folks:

    A list of packages in 7.4.2 DVD which may be able to be purged in order to mimic 7.2.0 CD is included in the attached tar ball. They are arranged based on their reversed dependency, the results of ' apt-cache -i rdepends ', relative to the ones at the adjacent level above; the packages on Level 1 don't have any packages which depend on them. At the same level, packages don't reply on each other, unless they are joined by the ampersand signs and are in dependency cycle.

    So far, after purging these packages with ' dpkg --purge --force-all ' when the persistent overly was in place, the mimic is still bootable and functional; the cheatcode of knoppix64 hasn't been tested. There is also no broken package listed in apt-get/aptitude. The total number and installed size, shown by dpkg, are 1547 and about 3GB (w/o compressed).

    As I'm new to Linux and Knoppix, this purge list probably contains some critical packages (related to 64bit stuff, maybe?) and some surplus. If you spot them, shear them, please!


    PS: A list of packages from 7.4.2 DVD which are in dependency cycle is also attached; the base system, the packages tagged with important and required and the ones which they depend on, were excluded when the list was built. Both lists in the tar ball are plain text files, not scripts.

    Nice use of apt-cache! I'm very curious about the size of a remastered image - I could have checked it out myself, but I'm busy with Debian live 8.0.0 - which btw has a squashfs footprint of ca 870 MB in the comparable LXDE version. Might take the package list (1354 packages, got upload error when I tried to upload it) from that as a starting/goal point too.

    In my experience, using Aptitude to make everything as auto-installed and than marking just the meta-packages you need does a pretty good job for removing the bulk of the bloat. One downside is that, even if you have Aptitude configured to not autoinstall recommends, it won't autoremove recommends. Do note that if you start manually removing packages, an important package might have to be added to your list of manually installed packages to avoid it being autoremoved(for example, at some point a linked dependency that kept busybox from being autoremoved got removed and now I have to mark busybox as manually installed to keep my system so it will boot to the Adriane Menu with speech in-tact). For what it's worth, I've only got 476 packages installed on my primary workstation and could get rid of another 200 if I could find a suitable text-mode replacement for Iceweasel. Then again, I'm far from a typical user and have basically gutted my xserver to the point it would be useless to a sighted user.

    @ Capricorny and Jeffery (in alphabetical order)

    Many thanks to you both for the feedbacks and sharing the first-hand experience. After purging the packages listed in one of the files attached previously, the uncompressed size of the main knoppix folder (/KNOPPIX) is 3089MB. By refreshing the icon-theme.cache files (gtk-update-icon-cache -i -f) and downgrading Iceweasel from version 32 to version 24, the size of the uncompressed folder can be reduced by 82MB and 75MB, respectively. Overall, the sizes of the main knoppix are 2932MB in the form of uncompressed folder (on ext4 partition), 2781MB for the uncompressed iso file and 1015MB for the file compressed with level 9 argument. The final compressed file is nowhere near being fitted in a CD or its size being comparable to Debian Live 8.0.0. If I am able to find more time later on, I will try to repeat the same procedure on KNOPPIX 7.2.0 DVD to see if I have missed something.

    Just for a side note, an upside of compressing the main knoppix folder with level 6 argument is (obviously) to reduce the compressing time significantly but a downside to have a approx. 6MB larger file.


    @ Jeffery

    It seems to being getting harder for the console-based browsers to cope with the modern websites, and I also miss the era when the web pages looked fairly primitive by today's perspectives. By the way, for a linux novice like me, your main workhorse seems to have a barebone linux setup. I would appreciate if a list of installed packages could be shared only if it is not too troublesome. Many thanks.

    If anyone knows how to generate a plain-text list of installed packages, I'd be glad to share it, though I doubt it would be of much use to the average user. For example, my install of X has been gutted to the point I doubt it would be useful to any sighted user. Regarding console web browsers, for the one's I've tried(elinks and a few of it's derivatives), I can't really judge their rendering do to being unable to figure out their interfaces. Last time I selected the WWW option from the Adriane menu, I couldn't even figure out how to load a page from a URL, and when I've tried in the past, I couldn't figure out how to get SBL to read anything other than links. By comparison, Iceweasel+Orca combined with Adriane's ability to launch a stripped down x session just for those two applications works so well, I'd think I was using a web browser built specifically for the blind if I didn't know better. Anyways, at present, my own set-up has: A 420-something mb /usr A ~30 mb /var that balloons to ~140 mb with files generated by the operation of Aptitude(files I make sure to clean out before making backups of my root filesystem). 457 installed packages, the bulkiest things(both in terms of disk usage and number of packages) being Iceweasel+everything I need to use it and mpv(wish I could find something with the same simplicity of use and audio support(including from video containers) minus the video codecs I have no use for. I don't even need compression to fit my entire root filesystem on a CD, though I still use bzip on my partimage backups.

    Many thanks for your time!


    @ Jeffery

    It is so true that your root filesystem does not even need to be compressed to fit on a CD. Besides, the direct output of the dpkg command with -l argument will be more than good enough for my need. Please don't bother with the formatting. Thanks again.

    Below is the list of packages I have installed. Some notes: If you need a full Graphical Desktop, it will need to be installed in addition to the below. Vanilla Knoppix includes Gnome, KDE, and LxDE, all 3 of which I have purged as much as I can while retaining the ability to launch Iceweasel with Orca from Adriane's Graphical Applications menu. If you don't need blind accessibility, you can probably remove the Adriane packages without any problems. If you need blind accessibility for someone unfamiliar with the Linux command line, you might want to add the Adriane metapackage. Of the Adriane packages included in the below list, Adriane-config gives you the Adriane menu with the help, www, and shell options, adriane-screenreader gives you text-mode screen reader support, and Adriane-x adds the Graphical Applications option to the Adriane menu and install the Orca screenreader and Compiz along with a core xserver. Busybox-static isn't anywhere in Adriane's dependency tree, but is still required for successfully booting into Adriane with screenreader. Network manager is, best I can tell, required to maintain internet access. sudo is required to maintain the ability to do administrative tasks. Ctorrent(command line bittorrent client), Fdupes(find duplicate files), iceweasel(Adriane's default graphical web browser), mpv(mediaplayer), nano(text-mode text editor), pmount(Wrapper for mount that doesn't require sudo and tends to making mounting external volumes simple from the command line), and tofrodos(convert plain text files between Dos and Unix formats) are all applications that can be safely removed if you don't need there functionality. Except for Iceweasel and MPV, they are self-contained command-line utilities with few if any dependencies. Any package I didn't mention by name is somewhere in a named aboue package's dependency tree if I haven't forgotten anything. My sources.list only has two lines: debian testing/main and the knoppix repository which I generally leave commented out, and where possible, I have force installation of a version from Debian Testing. There are cases of package having a knoppix specific version that is older than the Debian version, but uses a non-standard version number to appear newer, sometimes requiring a forced downgrade to get the newest version. I have done some other hacks that may not be appropriate to recommend for general use, but whose absence may require installing additional packages. For example, the vanilla copy of gconf2 requires python2.7 while orca requires python 3.4, and I hacked gconf2 to allow me to remove the older python version. Anyways, the list itself: adduser adriane-common adriane-config adriane-screenreader adriane-x adwaita-icon-theme alsa-utils apt aptitude aptitude-common at-spi2-core base-files base-passwd bash

    @ Jeffery

    Many thanks for your time to upload the list of packages currently installed in your system. I have tried to strip down the regular KNOPPIX to a similar extent to your version of Vanilla KNOPPIX. I reckon your setup is quite awesome and the included packages are kind of enough to boot up the regular KNOPPIX with X Window environment. At the moment, I only know two packages, hwsetup and pciutils, are missing from the list and will find some time later on to figure out the rest once I finish downgrading the X11 from 1.16 to 1.12. Sorry for the late reply.

    Wow. I'm really amazed that you were able to make this work Superman. You mentioned it may be possible a while ago, but it's quite a feat to have accomplished. I'm afraid this newbie is even having problems finding how to purge the list. But you've made it posssible Superman. Thanks. This is an important treasure for me.
