Here is the first try to create all partitons of a blockdevice, since
removable media devices may need to acces the expected partition to
revalidate the media.
It uses the attribute syntax introduced with the last %s{file} patch.
I'm using this with my multi-slot-flash-card-reader:
SYSFS{model}="USB Storage-SMC ", NAME{all_partitions}="smartmedia"
SYSFS{model}="USB Storage-CFC ", NAME{all_partitions}="compactflash"
SYSFS{model}="USB Storage-MSC ", NAME{all_partitions}="memorystick"
SYSFS{model}="USB Storage-MMC ", NAME{all_partitions}="multimedia"
and I get:
tree /udev/
/udev/
|-- memorystick
|-- memorystick1
|-- memorystick10
|-- memorystick11
|-- memorystick12
|-- memorystick13
|-- memorystick14
|-- memorystick15
|-- memorystick2
|-- memorystick3
|-- memorystick4
|-- memorystick5
|-- memorystick6
|-- memorystick7
|-- memorystick8
|-- memorystick9
|-- multimedia
|-- multimedia1
|-- multimedia10
|-- multimedia11
|-- multimedia12
|-- multimedia13
|-- multimedia14
|-- multimedia15
|-- multimedia2
|-- multimedia3
|-- multimedia4
|-- multimedia5
|-- multimedia6
|-- multimedia7
|-- multimedia8
|-- multimedia9
...
If needed, we can make the number of partions to create
adjustable with the attribute?
