View Full Version : 64-bit LXDE Debian.LiveUSB

03-24-2014, 12:57 AM
Partitioned 2 Gb SanDisk to 1200 Mb fat32, 800 Mb ext2; labeled ext2
as persistence; echoed "/ union" >> /media/persistence/persistence.conf.
Desktop time was already set to local; changed format to %l:%M %P.
Used external wifi to add b43, GParted & ttf-mscorefonts via Synaptic;
borrowed Knoppix's repositories for b43 & ttfs.
Added LibreOffice, Leafpad & Terminal to panel; set panel to auto-hide.
Removed Lock Screen & Minimize Windows from panel; added volume control.
Reduced browser cache limit to 25 Mb; adjusted fonts & underlines.
Added ChezHoye, changed homepage & added bookmarks.
Changed desktop image to Japanese print, adjusted background color;
removed Install Icon from desktop.
Added synclient TouchpadOff=1 to /etc/X11/Xsession.d/45x11-Synaptic
& ok to /etc/rc.local
Added Count & Channel apps to ~/.bashrc not /etc/profile.
Adjusted terminal font & foreground.

To do list:
Needs boot time parameter 'persistence' added for each boot.
May need terminate:ctrl_alt_bksp to restart screen.

With some effort the Debian.Live iso makes a fine LiveUSB with persistence.
The Debian.Live product's persistence approach, although elegantly simple, is
keenly obscured by its documentation. The iso carries Debian's disdain for 'non-free'
wifi drivers to an excruciating extreme. This may be overcome by temporarily applying
Knoppix's 'non-free' repository definitions to Debian.Live's Synaptic. Included
applications are not the very latest: Linux 3.2, LibreOffice 3.5, IceWeasel 17,
PCManFM 0.9.10, but that may contribute to the very stable and smooth feel of the system.

The basic system is contained in a normally ro compressed form on a squash
filestem in a fat32 partition; persistence is provided by a non-compacted rw overlay
in a second ext-formatted partition. There are adequate device assignments such that
numerous non-compact overlays might conceivably be compacted and transferred to
squashfs devices on the fat32 partition, but that's not currently advertised or developed
in any way that I know-of.

The trick to Debian.Live is as follows: make a second partition of est2, 3 or 4;
label that partition 'persistence'; provide a 'persistence.conf' file on the root (/)
directory of the ext partition; the conf file needs only one line '/ union';
finally, when you boot up with the other partition, include the parameter 'persistence'.
Forget all these quote marks as you apply this elegant process.

If you get tired of adding 'persistence' at boot with your Debian.LiveUSB, you can tweak
the initial choice menu a little. Add a persistent mode stanza, to live.cfg,
and let this be the new default. You need to do this with another Linux, MOUNTING
the Debian.Live unit inertly as a bunch of files, rather than executing it as a live system.
Mine showed up at /media/sdc1/isolinux/live.cfg. YMMV.
