For one thing, flash-kernel has hooks in both the kernel and initramfs-tools directories: $ dpkg -L flash-kernel | grep -E 'post' | grep flash-kernel /etc/initramfs/post-update.d/flash-kernel /etc/kernel/postinst.d/zz-flash-kernel /etc/kernel/postrm.d/zz-flash-kernel So, at the very least, on a new kernel install, it's likely to be called at least twice. > I'm afraid to touch that code and hope Ian will look into it at some > point. > > ... > Taking backup of tegra210-p2371-2180.dtb. > Installing new tegra210-p2371-2180.dtb. > flash-kernel: deferring update (trigger activated) > /etc/kernel/postinst.d/zz-flash-kernel: > DTB: tegra210-p2371-2180.dtb > Installing /usr/lib/linux-image-4.9.0-trunk-arm64/nvidia/tegra210-p2371-2180.dtb into /boot/dtbs/4.9.0-trunk-arm64/tegra210-p2371-2180.dtb > Taking backup of tegra210-p2371-2180.dtb. > Installing new tegra210-p2371-2180.dtb. > Installing /usr/lib/linux-image-4.9.0-trunk-arm64/nvidia/tegra210-p2371-2180.dtb into /boot/dtbs/4.9.0-trunk-arm64/tegra210-p2371-2180.dtb > Taking backup of tegra210-p2371-2180.dtb. > Installing new tegra210-p2371-2180.dtb. > flash-kernel: deferring update (trigger activated) > Processing triggers for flash-kernel (3.73) ... > DTB: tegra210-p2371-2180.dtb > Installing /usr/lib/linux-image-4.9.0-trunk-arm64/nvidia/tegra210-p2371-2180.dtb into /boot/dtbs/4.9.0-trunk-arm64/tegra210-p2371-2180.dtb > Taking backup of tegra210-p2371-2180.dtb. > Installing new tegra210-p2371-2180.dtb. > flash-kernel: installing version 4.9.0-trunk-arm64 > Generating boot script u-boot image... done. > Taking backup of boot.scr. > Installing new boot.scr. But this is obviously more than just that... and I've seen it too. *sigh* live well, vagrant
