"readahead" is the term used to refer to a tool that preloads files in this case used during the boot process to make the system boot faster. . This implementation of the tool provides the following features: * It can take multiple lists of files to be preloaded, and sort them according to their position on the disk. * It preloads the inode tables on ext2-based file systems. * It opens the files without making the system update their access time, therefore avoiding extra disk writes. * It uses a lightweight monitoring daemon.
