readahead list is completely silly

[Matt Zimmerman]

As discussed at UBZ, the current /etc/readahead/readahead is wildly inaccurate
and may even be slowing things down for some systems. We should generate a more
reasonable one for both breezy and dapper.

[Scott James Remnant (Canonical) (canonical-scott)]

The readahead lists are now completely less silly.

Generating a new one for breezy is possible with some fiddling, I don't have a breezy box to hand right now though.

*poke*

Are you still planning to do this? I can give you access to a breezy box if needed.

I believe anyone with a Breezy box can help with this; you should only need
to build and install the new version of readahead and boot with the
'profile' option on the kernel command line.

Right, Scott?

Did that, what's next?

[Scott James Remnant (Canonical) (canonical-scott)]

Right,sorry this fell out of my radar due to Malone's oh-so-helpful behaviour of not showing this bug up in ANY of my lists. Also I don't have a breezy box anymore.

Yes, please make sure you have a fresh breezy install (no extra packages installed, which will massively skew the results) and install the new readahead packages and boot with profile.

Then attach /etc/readahead/boot and /etc/readahead/desktop to this bug.

[Dennis Kaarsemaker (dennis)]

The no extra packages requirement is a bit troublesome, my breezy box is
in production use. Sorry.

Untill i have dapper cds i have a pretty unlimited supply of breezy boxes - is there something i can do to help here?.
I gather i need to run some stuff on boot, what specificaly?
And does "no extra packages" mean "after dist-upgrade to -10 kernel" or "on a fresh from the cd install"?

[Dennis Kaarsemaker (dennis)]

You could do both: generate a new list with the -9 kernel, upgrade and
generate one with the -10 kernel.

[Scott James Remnant (Canonical) (canonical-scott)]

1) Install the "readahead" package from dapper.
2) Reboot and add "profile" to the kernel command line
3) Attach new /etc/readahead/boot and /etc/readahead/desktop files

[KarlGoetz (kgoetz)]

Sorry for the tar - i wasnt sure if i should tar them or attach a dozen files.

Theres the desktop and boot files for 2 machines, with their dimidecode output.

I would have more, but i stuffed up the file copying, and a few boxes were awol. I will try and collect more data tomorrow and thursday if you need it.

can this be rejected for breezy? or should it stay as is.
