Compressing the Custom Partition Contents
The contents of a Custom Partition are packaged as a compressed tar file. You can easily create it on the Linux command line, e.g. on the thin client:
In the Local Terminal change in to the /custom/ directory: cd /custom
Compress the contents of the hello/ directory into an archive file named hello.tar.bz2: tar cjvf hello.tar.bz2 hello/ The result is a hello.tar.bz2 file, sitting side-by-side with the hello/ directory. You will upload it to UMS later.
