- | dd if=$name of=/ | + | If your tape media does not have a seglist file (the 2.1 image on this site does, so no worries there) you'll have to figure out the order of the files on the tape. If they are numbered sequentially already, just do ls > seglist but make sure that only tape installation files are in there, and not other things like the dtdist.sh script. If seglist is missing and the files aren't numbered, you need to figure out the order…list the cpio files you have until you encounter one with just two files in it: Version and List. cat the List file. The file containing Version and List needs to be the first onto the tape; everything else goes afterward, in the order specified in the List file. How you figure this out is up to you. The seglist just contains filenames in the order to go onto the tape. |

This step is also optional, but might save you some time in the long run. Take a look at the cpdist.sh script included with the tape creation script. Modify the device name to be 4hn if you have a 2.1 tape and run it in an empty directory, copying the seglist file into it before you run the script. If you get any errors, you can either try that tape again (retension, zero out, write tape) or try a new tape. No errors? You're ready to install, but it's wise to have a backup tape anyway! | This step is also optional, but might save you some time in the long run.
