Package: readahead
Version: 1:0.20050517.0220-1
Tags: patch
For automatic update of the readahead file list, it would be helpful
if one did not have to edit the grub configuration, but could get away
by touching a file on the disk to document that one profiling run
should be executed on the next boot.
I propose to use /etc/readahead/profile-once for this purpose, and to
use this patch to implement it. Julian, what is your view on this?
With it, we in Debian Edu could just touch that file at the end of the
installation to make sure the future boots are optimized.
