Hello,
udev appears to only be able to use my configured rules once. After
unplugging and replugging the same device, they are ignored. I'm using
a four-in-one flash card adaptor on my Debian system (kernel 2.6.9, udev
0.050).
In my /etc/udev/rules.d/iapp.rules:
-----------
BUS="scsi", SYSFS{vendor}="IN-WIN", SYSFS{model}="iAPP HS-SM", NAME="%k", SYMLINK="sm%n"
-----------
Here's the relevant bits of /var/log/syslog:
Plugging in the adaptor (with a CompactFlash card in it) the first time:

This creates the devices sda, sdb, sdc, sdd and sdc1 (the one partition on the
SM card), and the appropriate symlinks sm and sm1.
Without attempting to mount the card, unplug the adaptor:

To get the renaming to work again, I have to restart udev before
plugging the adaptor in. Any suggestions as to what's going wrong?

No idea. Maybe your tmpfs partition is too small?
What does:
df -kh /dev
print?
Thanks,

Filesystem Size Used Avail Use% Mounted on
none 5.0M 2.7M 2.4M 53% /dev
The Debian default udev.conf has
tmpfs_size="5M"
so I'd assumed that would be a sensible size.

Ok, don't know why there is a limit at all, but anyway...
What does:
udevtest /block/sdc/sdc1
print at the time you don't get the rule applied?

$ udevtest /block/sdc/sdc1
version 050
looking at '/block/sdc/sdc1'
opened class_dev->name='sdc1'
configured rule in '/etc/udev/rules.d/iapp.rules' at line 3 applied, added symlink 'sm%n'
configured rule in '/etc/udev/rules.d/iapp.rules' at line 3 applied, 'sdc1' becomes '%k'
creating device node '/dev/sdc1', major = '8', minor = '33', mode = '060660', uid = '0', gid = '6'
The output is exactly the same when the rule is applied correctly.
Oh, in case it's relevant, this isn't the stock 2.6.9 kernel - I have
the supermount-ng and fbsplash patches applied.

Can you try it with a stock 2.6.9 (or preferably a 2.6.10) kernel? The
supermount-ng crud might be getting in the way somehow.
thanks,

I'd hoped it wouldn't come to that...
[some hours later]
With 2.6.10 stock (and 2.6.10+fbsplash), the devices are all created
properly. Looks like I'll have to go back to using automount for
removable devices. Thankyou for your help.
