After installing readahead and after using this command:

Code: Select all
touch /etc/readahead/profile-once


I get:
Code: Select all
touch: cannot touch `/etc/readahead/profile-once': No such file or directory


No google results on this one.

The command is described as
Code: Select all
# touch /etc/readahead/profile-once


The # indicates that this command should be performed as root. If the $ symbol was in its place then you'd be expected to perform the command as regular user. If no symbol is present then either the context should mean it's clear or the author is a lazy so and so.

Perhaps you're running Squeeze? I notice that in Squeeze readahead has been superceded by readahead-fedora which I assume is different (I didn't try it). If so then you should consult the man page on your system in preference to using this howto's readahead info. I've edited the howto accordingly.

The error message implies there is no directory named readahead under /etc (which is weird because normally apps take care of those at install or at first run). Maybe create one and try again?

The profiling seems to be called only when needed, I don't think you need to do anything other than install it. You'll note that when installing or removing a system service readahead is automatically called during the update. Maybe insserv or something? Nothing of interest could I find in the man page... an undocumented change perhaps?

I believe the readahead command for Squeeze to profile once on the next boot is

Code: Select all
# touch  /.readahead_collect

Hi!

First of all I have to tell you I really liked your HOWTO, especially to have such a lot of things in one place. (bookmarked it)
My quiestion is:
-is there any use of giving the noatime option in fstab to my NTFS mounts (ntfs-3g), mostly I have documents and music on this data partition, shared with the Win7 OS.
Thanks for the great HOWTO again.

Sorry for the stupid question. I gave it a try and found out that it's not possible to give that option with that fs.
