Today I finally got a couple of USB 1-wire dongles so naturally this
evening I'm installing the latest owfs. :-)
I followed Peter Kropf's advice for the hot plug script:
#!/bin/bash
#
# setup a usb 1-wire controller to allow access from users in
# the owfs group.
GROUP=owfs
if [ "$ACTION" = "add" ] && [ -f "$DEVICE" ]
then
# check if $GROUP really exists
if getent group $GROUP > /dev/null; then
chmod 660 "$DEVICE"
chown root.$GROUP "$DEVICE"
fi
# remove the kernel driver so that we can control it from user
# land
if /sbin/lsmod | grep ds9490r > /dev/null 2>&1; then
/sbin/rmmod ds9490r
fi
fi
and indeed the /proc entry has group owfs after that. But I don't
understand why you want the rmmod? It seems to work just as well if I
comment out those lines and leave the module loaded.
This also does not change the permission of the mounted fuse
filesystem. How do I do that? I would like to have group rw
permission for /mnt/ow0 but right now only root can do anything, even
though the permissions look like this:
drwxr-xr-x 3 root root 1 Jul 12 22:35 /mnt/ow0
I have a little experience with scripts for hot-plugging network-like
interfaces, for example when I plug in my Zaurus to the USB cradle,
the network interface usb0 is created by the usblan module and then
/etc/init.d/net.usb0 is called to configure it; but net.usb0 is a
generic network config script which gets the configuration info from
/etc/conf.d/net. So I imagine we can do something similar for owfs -
there can be an /etc/init.d/ow.usb0 which takes care of mounting
/mnt/ow0 and starting owhttpd etc., with a conf file elsewhere to
disable some of the services if necessary.
Is anybody working on a Gentoo ebuild yet?
