suspend-hibernate read ahead (SHRA) increases the response time of running programs when coming out of suspend states on Linux.

suspend-hibernate read ahead aims to support all init-style Linux distributions through run-control startup scripts.

Hibernation-suspend readahead is a simple script that loads the libraries of currently
running programs into memory after a come-back from hibernation or suspend mode.

In simple words, hibernate readahead reduces the response-time (interactivity) of already running programs on your way out of suspend or hibernate mode.

The idea is very dumb and simple and is init-style portable (BSD and SYSV).

Installation:

Type 'make' for starters.

For the impatient, 'make install' to install as a daemon into your configuration scripts.

The installer only knows about BSD and SYSV style inits. I can't guarantee that other distros other than Slackware-based and Debian-based would work.

The installer is non-destructive (as far as I know). It adds configuration information into your run-control scripts but does NOT pollute them destructively. That is if you uninstall shra you won't have to worry about left-over chunks of code messing your system.

Example:

In slackware, /etc/rc.d/rc.hreadahead is referenced in /etc/rc.d/rc.local as such:

# hreadahead reference for Slackware

if [ -x /etc/rc.d/rc.hreadahead ]; then
. /etc/rc.d/rc.hreadahead
fi

rc.local is a script used by many programs to reference to start-up scripts. While the installer cannot automatically remove the above line from the rc.local script, it is safe to leave it there since the 'if' check will fail silently or should I say succeed?


What's New in This Release:
run-control scripts now apply and install cleanly.
The script has been daemonized.
Installation works OK for Slackware and Ubuntu users.
