i can trivially create misc character devices, and i know special
device files for them will automatically show up under /dev, but what
is the precise udev event/rule that comes into play for this?
if i start to monitor udevadm with:
$ udevadm monitor --kernel --udev --property
and insert my misc char module, i see:
KERNEL[5342.740294] add /module/mymisc (module)
ACTION=add
DEVPATH=/module/mymisc
SEQNUM=3007
SUBSYSTEM=module
KERNEL[5342.740528] add /devices/virtual/misc/mymisc (misc)
ACTION=add
DEVNAME=/dev/mymisc
DEVPATH=/devices/virtual/misc/mymisc
MAJOR=10
MINOR=55
SEQNUM=3008
SUBSYSTEM=misc
UDEV [5342.741071] add /module/mymisc (module)
ACTION=add
DEVPATH=/module/mymisc
SEQNUM=3007
SUBSYSTEM=module
USEC_INITIALIZED=740419
UDEV [5342.741921] add /devices/virtual/misc/mymisc (misc)
ACTION=add
DEVNAME=/dev/mymisc
DEVPATH=/devices/virtual/misc/mymisc
MAJOR=10
MINOR=55
SEQNUM=3008
SUBSYSTEM=misc
USEC_INITIALIZED=740750
so, yes, i can see the line "DEVNAME=/dev/mymisc", but is there
something i can point at in the collection of udev rules that deals
with that? or is that simply done internally?
