NAME

       readahead-collector - collect list of files used during the boot process

SYNOPSIS

       readahead-collector [options]

DESCRIPTION

       readahead-collector is a files list generator for use in readahead(8) based on the files used during the boot process.

       Note: readahead-collector uses the audit subsystem of the kernel
	      to  gather  the  list  of  accessed  files; for this reason, it is necessary that the kernel is built with the CONFIG_AUDIT and CON-
	      FIG_AUDITSYSCAL options enabled.	Stock Debian kernels are built with these options.

OPTIONS

       -d     enable debug mode.

       -f     leave the daemon in the foreground for debugging, output goes to stdout.

       -h     print the usage information.

FILES

       /etc/readahead.conf
