[yocto] Modify udev

[Jack]

Hi,

In my imageو starting udev take a long time about 6 seconds whereas the time
is so important for me. Therefore, I decide to remove udev from
task-core-boot but I get a problem in mounting SATA drive. So, I add udev to
task-core-boot. In addition to mount SATA drive by udev some other packages
like libusb, pciutils,... will install. I want only to mount SATA drive by
udev. How can I modify udev that it only install hdd drive ?

Thanks.
