According to the "New Plugger How To" document
Edit /etc/rc.local. The two insmod commands fail, and because the shell is invoked with the -e flag (see first line of the file), a failing command causes the whole script to exit. Delete or comment out all lines except "mkdir -p /var/cache/apt/archives/partial". You might also want to add, after the mkdir, a line "/usr/sbin/ntpdate-debian" to automatically sync your clock over the network.
When I do this, I end up commenting the
insmod /boot/fat.ko
insmod /boot/vfat.ko
which means I loose the FAT/FAT32 support. Isn't that right ?
