In order to prepare the double-six movie as documented earlier, I had to get povray running on IMSc's fastest machine available for general use; that turned out to be running the amd64 version of Debian and povray is 32-bit only! Luckily, I found a write-up on the Debian wiki that helped me solve this problem with schroot.

Later, I read some letters to Linux Weekly News where people said that Debian was hindering those who want to run flash and other 32-bit programs on a 64-bit system. I couldn't let that pass unchallenged!

Here then is another write-up explaining how one can use schroot to solve the above problems (and perhaps a number of others). The Linux Gazette has also published this in Issue 150 --- thanks Ben!
