Re: Speed up the boot by loading the kernel disk cache

Thanks for taking care about this. It's also quite important to speed up live systems that use squashfs (like debian-live), because the output of readahead can directly be used by mksquashfs via the -sort command. -- Address:Daniel Baumann, Burgunderstrasse 3, CH-4562 Biberist Email:

Speed up the boot by loading the kernel disk cache

Today a new package to speed up the boot is available in unstable. The readahead binary package can speed up the boot quite significantly by optimizing how the hard drive is used. It make sure the kernel disk cache is populated as the very first thing done at boot with the files used during boot.
