haha, the 32mb VPS challenge.
And if you remove the cron, maybe you can get something better... and syslog, I dont know if you need syslog on these machines.
Optimizy!
@netomx I still remember when you forced me to manually install centos on my debian test machine 4-5 months ago and now you are all peace and love with debian :-)
And give suggestion on how to run it in 32M! You're a man now!
:P
Thats only file system optimazation though. You can also optimize the CPU with
If we use Debian 6 32 bit :
# free -m total used free shared buffers cached Mem: 32 11 20 0 0 7 -/+ buffers/cache: 4 27 Swap: 32 0 32@gsrdgrdghd thats just evil..
I used Debian 6 32bit. @prometeus i know
hahaha
apt-get install syslog-ng, much less RAM than normal syslog.
Someone willing to explain this one to me?
@gsrdgrdghd: Since when are fork bombs considered as optimization?
@djvdorp: It's a 'fork bomb'...
http://en.wikipedia.org/wiki/Forkbomb
Since @breton 's code removed root (i suppose) :P
@gsrdgrdghd: Valid point! ;-)
great a 2mb system that does nothing weeeeee

Well, that is just to lower the RAM - you can try not to use rsync, apache2, whatever

I hate you
Will the Minimal works with OpenVZ without error?
Yeap

I should install localepurge then, to preserve space with new packages

Thank you LET! Today I learned about forkbomb

that conversion to svg failed
@djvdorp why?
