at my point of view, it is easier to upgrade on debian... I managed CentOS 5 several years ago and never feel so good of it...
I prefer debian myself. But i was pretty much trolling with memes as buyvm guys arent here
32M box from IPXCore

@huluwa how were you able to drop disk usage to 312mb? mine is 480mb after installing debian 6.
I also have the same question... Maybe, logs, or removal of some bulk?
I removed many others:
apt-get -y purge lynx memtester unixodbc python-* odbcinst-* sudo tcpdump ttf-*

EDIT: Used the minimal.sh script from Maxexcloo...

thanks! thats a big help!
You guys just aren't trying hard enough
2/3MB RAM usage and 85MB disk for a fully updated Debian 6 build (Sticking to SSHD and BASH as well)
https://www.thriftydevil.com.au/technology/minimizing-debian-for-openvz
Yes, but you don't mention how to achieve it...
no consolidated script =(
Yep
But I am afraid this implies removing files at hand, which isn't the best idea always. Sounds cool, but...
i can live with 180mb from maxexcloo, with script i understand.

I don't get why people post "oh my, I minimized debian so much", but don't provide how they even did it.
It just involved removing some of the locales and a few parts of the docs (the same copyright message repeated 100 times!) etc.
I'll write something in more detailed later, but rather than running the scripts blindly, you guys should be looking at what each command does anyway... That way you can combine all of the guides online.
I got powerdns and MySQL backend running on my 32MB IPXcore VPS. Works fine. :-)
Running CentOS btw.
Hooray people like my script
Just FYI, Minimal is depreciated, I'd recommend Minstall instead (will have automated install soon)!
Can you add support for Ubuntu ?
Interesting result with minimal.sh ...it removed aptitude and then freaked out because it couldn't continue without aptitude. I blame Debian...
Minstall, you're up
Hi @Oliver would you mind sharing your mysql and pdns config on that 32MB?
I also have pdns setup on Amanah free vps 64MB (burst to 128), it uses 94MB right now.

It's allocated 94MB, not really using that much. Most by the pdns_server. You need to look at /proc/user_beancounters to see actual memory usage.
I heard rm -rf /* will reduce your disk usage to 1KB.
This is what happens if you remove init, you get the best RAM savings but you remove all functionality.
To be fair you don't have any free RAM left
But im using the least RAM.
Ya mostly by pdns service. But after a little change on the pdns.conf:
It reduces a lot. But I don't know maybe @Oliver has another recipes to make it as small as possible.
Very odd, is this with stock Debian 6?
Convert all the tables to MyISAM so you can disable innodb completely.
Reduce distributor threads as you have already.
Adjust all the MySQL settings down as much as possible obviously.
