I think the below link is one of the good input to start for USB stick based linux flavour. http://www.linux.com/distrocentral/distronews/8221-comparing-linux-usb-flash-disk-distros But, it does not clearly convey the method of addition of new softwares/applications to USB stick based linux. I assume that i need to set up the network/internet and download the application/ software of interest(anti-virus, etc ) once the linux boots up from the USB stick and occupies the RAM. Another possible method could be to add the software/application to a particular folder in USB Stick so that it gets added into a directory from where it could be executed to get installed once the ubuntu gets booted off the USB stick and occupies the RAM. For setting up ubuntu in USB stick - http://www.pendrivelinux.com/usb-x-ubuntu-610/ Setting up ubuntu in USB stick from Live CD - http://www.techbuzz.in/installation-of-ubuntu-in-a-usbflash-drive-from-the-live-cd.php Incase of ubuntu, http://www.pendrivelinux.com/usb-ubuntu-710-gutsy-gibbon-install/ I think, after the below step, the application/software can be copied into the USB folder itself. ' Download UBconvert.zip and extract the files to the USB folder ' But, not sure. Any ideas ? Any trick for adding the application/software so that the application comes by default when it gets booted up from the USB Stick instead of adding it everytime ? That is , it need not be installed once the linux gets booted up from the USB stick ? Still searching for information w.r.t this.

There are several methods for doing this, but if you're going to save it on a separate partition on the USB stick - as opposed to making it part of the boot image - then I recommend formatting that partition with a UNIX-style filesystem, i.e. ext2/3, reiserfs, XFS or JFS, but not with FAT32, as that does not honor the UNIX permissions and file ownerships. > Any trick for adding the application/software > so that the application comes by default when it gets > booted up from the USB Stick instead of adding > it everytime ? That is , it need not be installed > once the linux gets booted up from the USB stick ? Either use an ext2/3 or similar filesystem on the USB stick and save it to that, or add it to the boot image from which the GNU/Linux system boots up from the stick. If push comes to shove, you can temporarily save the downloaded files to a /tmpfs/ - i.e. a temporary filesystem in RAM while you are fiddling with the USB stick. >> http://www.distrowatch.com > > Nice link ! > This link would be of great help to me. It is fantastic. > Your response has been very helpful !! That link is known to just about every GNU/Linux user. ;-) As you didn't seem to know about it yet until I mentioned it here, you're probably not a real GNU/Linux user... :p -- *Aragorn* (registered GNU/Linux user #223157)

Right, you need to add clamav, after you have built the stick, but this is very straightforward. The penstick will be updated to reflect changes as packages are added or removed. (It works justs like a regular installation). I've got some notes on the creation of the bootable pendrive somewhere. I will try and dig them out for you.
