Re: [PATCH] udev-extraconf: Avoid mounting unknown filesystems

[ChenQi <Qi.Chen@windriver.com>]

Hi Otavio,

This patch caused a new bug. So I'm afraid maybe this patch is not 
totally correct.
https://bugzilla.yoctoproject.org/show_bug.cgi?id=4487

The problem is that for a cdrom device, there's no ID_FS_TYPE.
Any idea?

Besides, could you please detail a little about what problem this patch 
is trying to solve?
Which kernel version is involved?

Best Regards,
Chen Qi
