what mainly required for a lightweight livecd??

[Mohd Izhar Firdaus Ismail]

I'm stuck ... lol ...

I'm trying to create a lightweight liveCD ... but failed miserably due
to perhaps poor package selection (and lots of my carelessness)

... anyway .. I want to know what packages are minimum for a distro
that have X, a login manager, a desktop , a web browser ..

firefox have lots of dependency .. and elinks is too geeky ... the
target for this liveCD are old systems with around 192-256MB RAM ...

and btw .. do i need to shrink the kernel to reduce memory consumption?
