I know it's long, but I recommend that you read the entire web
page before starting.  There's a lot of material there, and many
"gotchas" are documented.  If you read the web page first, you
will avoid most of the common "gotchas".  If you are talking
specifically about the hook scripts, what I use is the lynx
browser (text mode only) to do the download.  Bring up the web
page in lynx under Debian for s390.  Position to the first
download link, then press "d" to download.  Exit the browser,
become root, move (mv) the file to /etc/kernel/postinst.d, change
the group to root (chgrp), the owner to root (chown), and the
attributes to 755 (chmod).  Revert back to your non-root userid
again, run lynx, position to the second download link, type "d"
to download, exit lynx again, become root, move the second file to
/etc/kernel/postrm.d, and change the group, owner, and attributes
as before.  Then edit /etc/kernel-img.conf and change do_symlinks
to no.

There are examples in the web page itself, but they are for the
i386 architecture.  Slight changes will need to be made in the
kernel naming convention for s390 kernels, but other than that
the examples in the web page itself should suffice.

After reading the entire web page, if you still have specific
questions, ask away.
