I tried following my own suggestion - transferring CentOS netinstall
to a USB stick with liveusb-creator (on a Fedora-14 laptop).
But to my surprise this failed with the error message
        ISO MD5 checksum verification failed

However, md5sum seemed to find the ISO OK:
[tim at blanche Documents]$ md5sum -c md5sum.txt.asc
CentOS-5.5-x86_64-netinstall.iso: OK
sha1sum also finds it OK.

I tried downloading the ISO again, but the outcome was the same.

The ISO is very short - just 10MB.
But it looks OK when I loop-mount it.

I wonder if anyone can cast light on this?
