You said "useful for *my* flow",
so you can do whatever you think is useful in
${HOME}/bin/${INSTALLKERNEL}, can't you?




$ cat ~/bin/installkernel
#!/bin/sh

echo '== useful info for my workflow =='
echo "$@"
echo '================================='

exec /sbin/${INSTALLKERNEL} "$@"




$ chmod +x ~/bin/installkernel

$ make install
  INSTALL /boot
== useful info for my workflow ==
5.17.0 arch/x86/boot/bzImage System.map /boot
=================================
