Description Evgeny Stambulchik 2005-01-06 01:31:04 UTC

I had /etc/udev/permissions.d/99-local.permissions containing a single line for my scanner:

# scanner
sg3:root:disk:0666

However, this was ignored by udevstart. Apparently, once a match is found (/etc/udev/permissions.d/50-udev.permissions has a generic sg*:root:disk:0660 setting), you can't override it with a more specific rule. I solved the problem by renaming my local file to 00-local.permissions so it's parsed before the defaults, but it's really weird IMHO.

Reproducible: Always

udev doesn't handle it on a best match basis, but on a first match basis. udev
reads the files in increasing order and takes the first match it finds. Your
own settings should go into a file smaller than 50-udev.permissions so that they
are found before 50-udev.permissions.
