I'm not sure how you would get even close to 32GB for an Linux OS unless you are adding oodles of features and have lots of cute graphics files or mountains of data. Did you have 32G reserved for the OS or for the OS + Data?

• Damn Small Linux clocks in at 50 Mb. (yes Mb, 0.05G). This is a Debian based (but not exactly Debian) distro.
• Feather Linux which is Knoppix based clocks in at 150Mb
• Debian itself offers a 650Mb CD image and a 4.4Gb DvD image - see http://www.debian.org/CD/http-ftp/#stable

According to Debian the installed size of Apache server is 100K. The installed size of MySQL client is 50K and MySQL server is 88K. Perl is part of the OS. So your packages add less than 250K.
