Re: boot speed

I switched to ext4 file system, and installed readahead-fedora. 
Boot is about 10 seconds faster.
Unless it is a new kernel then slower the first few times.

Re: boot speed

Lots of things you can do.  Ext4, if you don't already gave it, can make things slightly faster.  Readahead can make a big difference but sometimes it doesn't for various reasons.  Disabling unnecessary services is bound to help.

Knowing how to improve means knowing what is slow.  Use bootchart and see what is taking time, then see if you can make it faster or even remove it.  Post it here for suggestions.

Re: boot speed

Install rcconf by running 

sudo apt-get install rcconf

and run it as root

sudo rcconf

Then remove any services you don't need. (If in doubt, ask here)

Let's do it and don't screw it.

I see bootchart isn't in Squeeze...both `aptitude search bootchart` and `apt-cache search bootchart` yield nothing.  I guess it would have to be downloaded & installed locally.

Is there anything else in the Squeeze repo that has similar functionality?

~/.Sage of PV
It's listed in Sid/Unstable.... There's even a bootchart2 package, whatever that is.

Installing readahead-fedora is indeed a good option if you're using Ext3 or Ext4 journaling. Not so good if you're on XFS.
For big gains, if you're feeling experimental (or just mental) you can try systemd.

Read some good things mentioned about it recently over at various @freenode channels. Possibly the best option on Debian with regards to reducing boot times this side of an OCZ Vertex.

Re: boot speed

That systemd looks interesting.  It is a complete replacement for the /sbin/init base process with some features like mounting and fscking built in.  It won't be able to do things like removing services you don't need though wink
