[Vipul] Getting below message wondering why? Did I missing anything? I did execute make -j4 O=/home/playground/linux/build before executing below.
linux-tssh:/home/vjain/playground/linux/linus-stable # make O=/home/vjain/playground/linux/build install
make[1]: Entering directory '/home/vjain/playground/linux/build'
sh /home/vjain/playground/linux/linus-stable/arch/x86/boot/install.sh 4.8.0-rc5-42-desktop arch/x86/boot/bzImage \
System.map "/boot"
You may need to create an initial ramdisk now.
make[1]: Leaving directory '/home/vjain/playground/linux/build'
