Very funny, that after reading the wiki and installation guide, I'm still not able to install TC on my usb...
The thing is I use DSL modem to connect, and to setup the connection to download the needed dosfstools and syslinux I need to edit the resolf.conf chap and pap, options all under root I presume, and what is the the root password then?)
Maybe there is another workaround for this, but I haven't found one so far.
It is quite obvious that the majority of users would try to use TC on usb stick first, and not having a decent on-board usb-installer is not convenient.
