Remastersys is meant to be run from a normal install. You can do what you are doing but it won't be ideal. What changes did you make to the original filesystem.squashfs?
thanks for your reply fragadelic,
I would use remastersys if i could, but i don't have the space to do a full install + store all the remastersys temp files and a completed ISO. As i realised what i'm trying to do is basically similar to remastersys' process i just thought there might be some insight to gain by checking here.
The only thing i changed in the ISO's filesystem.squashfs was purely cosmetic (as a preliminary test) - a change of wallpaper and cursor - I just wanted to see if that would work before making more involved changes.
As it is though, I'm quite confused with the "time garbled" and the atd error and would not know where to start in finding the cause, but i would guess its something daft. If you don't have any clues then i might just ignore it or give up, not sure which yet though.
