[PATCH] kbuild: show the install image name and path

[PATCH] kbuild: show the install image name and path

[Keith Busch]

From: Keith Busch <kbusch@kernel.org>

Prior to commit f774f5bb87d13 ("kbuild: factor out the common
installation code into"), a 'make install' would print out the install
command like:

  sh ./arch/x86/boot/install.sh 5.18.0-11935-gbffe08031c89 \
        arch/x86/boot/bzImage System.map "/boot"

This output was very useful for my workflow, so this patch prints it out
again. I'm not sure if there's a better way to do this than what's
implemented here, so any feedback is appreciated.

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
=================================

True. E.g., my kernel installer also shows me

a) the modules install path (e.g., /lib/modules/$KERNEL_RELEASE)
b) the number of modules installed

Thanks for the suggestion, that works for me!
