mkinitrd is a script used to create an initrd filesystem.
For example, to create an initrd that contains the modules required for booting from a strange device one might use:
mkinitrd -o myinitrd
The file myinitrd could then be placed in the /boot filesystem and loaded by the kernel at start time.
mkinitrd [-k] [-d confdir] [-m command] -o outfile [-r root] [version]
- Do not delete the temporary working directory.
- -d confdir
- The configuration directory is usually
/etc/mkinitrd-- use this to override.
- -m command
- Override the command that creates the initrd filesystem.
- -o outfile
- The file to create the initrd filesystem inside.
- -r root
- Override the root options.
- The kernel version to use (the currently running kernel by default).
