I want to install CentOS 6.2 on a laptop (Thinkpad R40) which comes without CD/DVD-drive but with USB 2.0 ports.
It seems that CentOS does not provide ready-to-use dd-able USB images for installation.
Thus my question: How to install CentOS via a USB device (e.g. a 16 GB USB flash drive)?
Regarding using different available iso-images as base: the laptop has net-access - but I want to make sure that the CentOS installer is not loading unchecked packages from the net during installation - perhaps a netinstall image does not check cryptographically signed packages during installation (as with the Fedora 14 installer).
There is a CentOS InstallFromUSBkey which just provides outdated, cryptic and wrong information.
Especially, the instructions for CentOS 6 are missing details and contain errors (10 MB for the first partition is not enough,
syslinux device fails and what are they talking about grub?)
