Hi Kernel Alias,
I downloaded latest kernel source from kernel.org and tried to build it
at a directory outside source by giving O=<path option> but I noticed that
initrd image is not getting build but if I execute make inside source
things are fine.
[Build Kernel/Modules etc inside source]
~/linux-stable/> make
~/linux-stable/> make install
~/linux-stable/> make install_modules
~/linux-stable/> su -c "reboot -f"
everything works out fine and system gives me selection to boot from
newly build kernel and system boots up without issues. But if I build as
below I see system OOPS because no file system found for mount. Would
like to know why?
[Build outside]
~/linux-stable/> make O=~/linux-build/
~/linux-stable/> cd ../linux-build/
~/linux-stable/> make install
~/linux-stable/> make install_modules
~/linux-stable/> su -c "reboot -f"
Regards,
Vipul.

Don't do that.

make O=~/linux-build install

make O=~/linux-build install_modules

[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'
