Aagghh, torn between desire to be helpful and aversion to unnecessary
reboots, ears bleeding...
There also exists a file /etc/readahead.early.files. These two files
are used by the two init.d scripts /etc/init.d/readahead mentioned
previously, and /etc/init.d/readahead_early. For runlevel 5 the
symlinks are S04readahead_early and S96readahead. From the
description at the top of readahead_early:
This service causes the programs used during startup \
to be loaded into memory before they are needed,\
thus improving startup performance
Stay tuned for boot times....
