That would be a welcome upgrade.

Among other things, hotplug-1.0 supports the possibility of setting
envvars in some rule and then use it in another. So we can change the
rules from something like
...
DEVICENAME ~~ (null|full|ptmx|tty|zero|gpio) {
makedev /dev/%DEVICENAME% 0666
next
}
DEVICENAME ~~ (tun|tap[0-9]) {
makedev /dev/net/%DEVICENAME% 0644
next
}
...
to something like
DEVPATH is set {
setenv FILEMODE 0644
setenv FILEGROUP root
}
...
DEVICENAME ~~ (null|full|ptmx|tty|zero|gpio) {
setenv FILEMODE 0666
}
DEVICENAME ~~ (tun|tap[0-9]) {
setenv DEVICENAME net/%DEVICENAME%
}
...
DEVPATH is set, ACTION == add, MAJOR is set, MINOR is set {
makedev /dev/%DEVICENAME% %FILEMODE%
chgrp /dev/%DEVICENAME% %FILEGROUP%
}
DEVPATH is set, ACTION == remove, MAJOR is set, MINOR is set {
remove /dev/%DEVICENAME%
}
The main benefit being of course to cleanly support not only the
creation of the device nodes, but also their removal.
