Ah, that will break /etc/init.d/halt.sh
Particularly the stuff around here:
ebegin "Saving device nodes"
...
cd /dev
# Find all devices
find . -xdev -type b -or -type c -or -type l | cut -d/ -f2- > \
"${devices_real}"
# Figure out what udev created
eval $(grep '^[[:space:]]*udev_db=' /etc/udev/udev.conf)
if [[ -d ${udev_db} ]]; then
# New udev_db is clear text ...
udevinfo=$(cat "${udev_db}"/*)
else
# Old one is not ...
udevinfo=$(udevinfo -d)
fi
# This basically strips 'S:' and 'N:' from the db output, and then
# print all the nodes/symlinks udev created ...
...
The script will be unable to figure out what device is being handled by
udev, and what is not.
