Yes, every time I build a kernel. My kernel build system involves
typing "kbuild <flags> <dirname> <machines...>" and the kernel gets
built in ../build/<dirname>. When the build completes, it gets
installed into ~/systems/<dirname>, tar'd up, and copied to the
destination machines, unpacked, installed as appropriate, and
the machine rebooted if requested.

The installation step is done via the ~/bin/installkernel script.

My scripts deal with all that.

However, I haven't been able to review the changes that are being
made because I have no visibility of the common "scripts" version.
Provided it offers exactly the same functionality as the arm32
version, I'm happy. If it doesn't, it may cause a regression, and
I will be reporting that.
