![]() Initramfs Making a CPIO archiveĬhange directories to the root of the file system that you want to turn into an initramfs. ![]() Both RAM disk types can also be optionally built directly into the kernel, resulting in a single binary. If there isnt sufficient available memory to create the RAM disk you have requested, the mkramdisk command will alert you. RAMDisk is a free and open-source Linux software that makes it easy to create a ramdrive (to use part of your RAM as a drive). Both initrd and initramfs can be compressed with gzip (or similar) providing the option to decompress the chosen type is enabled in the Linux Kernel. With initramfs a cpio archive (like tar but simpler) is supplied and the kernel unpacks the archive into a tempfs file system. With initrd an image of a file system is supplied and is made available via a special block device. There are two ways to make a initial RAM disk for the Linux kernel: initrd and initramfs. This makes cleaning up these file easy since all I have to do is rm -r mydir. The original intention was for this "temporary" root file system to perform preparations before mounting the main root file system (for example loading kernel modules to talk to complex storage devices), however, in many embedded systems the initial RAM disk is the final root file system. Damn it You ran the script on the wrong computer. ![]() At the end of the script, display the start time, end time and total running time of the script. When the Linux Kernel boots you can optionally specify an initial RAM disk which allows a root file system to be loaded into memory. Make a log file with data on all created folders and files (full path, creation date, file size). Working with Linux Initial RAM Disks Introduction
