log files of setup

[bertrand marquis]

Hello,

i need to install a small cygwin from a cd-rom.
So i downloaded what i need from a mirror and then put it on a cd.

Then i made a bat script to run setup automatically specifying all the
options i need :
setup.exe -q -n -L -5 -l D:\ -R C:\cygwininstall

this is working well from a hard drive but from a cd-rom, as there is no
write access the setup is complaining that it cant't open D:\setup.log

is there any option to disable log file ?

thanks

bertrand
