I'm downloading the openSUSE beta4 delta ISOs, but I'm using SuSE 9.2 which doesn't have applydeltaiso in the deltarpm package. If you're in that situation too, here's what to do: Just download the SuSE 9.3 version of deltarpm from ftp.suse.com, and install it instead. Or, if you don't want to risk messing up your nice 9.2 system with odd packages from 9.3, install it like this: 'sudo rpm -ivh --relocate /=/home/james/opt/93stuff/ deltarpm-2.2-3.i586.rpm' (with the path changed for your system of course), and then copy /home/james/opt/93stuff/usr/bin/applydeltaiso to somewhere nice (/usr/local/bin sounds sensible, although I used /home/james/opt/bin) and it should all work. It may also work on non-SuSE systems. Who knows? Anyway, it should save a bit of bandwidth, and hopefully I'll actually find time to install this beta.
