andy,
as noted in the last line, the first virtual device number should
start with zero, eth0:0, so if you use one of the cool scripts above
remember that! ( this is noted in the NET3 HOWTO ) furthermore, while
i'll admit i don't use 'make' to manage my virtual hosts on my web
server ( yet :P ) it is relatively easy to set up a Makefile as
craig has suggested and that would most certainly be the "elegant"
way to help you manage your 200+ virtual hosts.
good luck!
