If you regenerate kernel modules for a custom kernel (using
automatic regeneration of the initramfs. In some cases, such as a system with a root filesystem mounted over a ConnectX card, not
regenerating the initramfs may even cause the system to fail to reboot.
In such cases, the installer will recommend running the following command to update the initramfs:
dracut -f
On some OSs,
dracut -f
libkmod: kmod_module_new_from_path: kmod_module 'mdev' already exists with different path
The "mlnx_add_kernel_support.sh" script can be executed directly from the mlnxofedinstall script. For further information, please see '--
add-kernel-support' option below.

On Ubuntu and Debian distributions drivers installation use Dynamic Kernel Module Support (DKMS) framework. Thus, the drivers'
compilation will take place on the host during MLNX_OFED installation.
Therefore, using "mlnx_add_kernel_support.sh" is irrelevant on Ubuntu and Debian distributions.
Example: The following command will create a MLNX_OFED_LINUX ISO image for RedHat 7.3 under the /tmp directory.
# ./MLNX_OFED_LINUX-x.x-x-rhel7.3-x86_64/mlnx_add_kernel_support.sh -m /tmp/MLNX_OFED_LINUX-x.x-x-
rhel7.3-x86_64/ --make-tgz
Note: This program will create MLNX_OFED_LINUX TGZ
All Mellanox, OEM, OFED, or Distribution IB packages will be removed.
