[Kernel Build] Initrd not getting build out of source dir
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.
~/linux-stable/> make install
make O=~/linux-build install
~/linux-stable/> make install_modules
make O=~/linux-build install_modules hope this helps, greg k-h

[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'
~/linux-stable/> make install_modules
make O=~/linux-build install_modules
hope this helps,
