具体参考这个回答: https://askubuntu.com/questions/1150434/what-is-udev-and-tmpfs
udev 是一个虚拟设备,作用是用户和物理设备之间的交互。
对于怎么处理,答者的原话是“ They run from RAM, they don't eat up actual disk space, and they play somewhat important purpose in the system.” 不会占用实际物理空间,也不要动它们。
Filesystem Size Used Avail Use% Mounted on udev 2.9G 0 2.9G 0% /dev tmpfs 594M 688K 593M 1% /run /dev/sda2 45G 927M 41G 3% / tmpfs 2.9G 0 2.9G 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock /dev/sda1 512M 13M 500M 3% /boot/efi tmpfs 594M 0 594M 0% /run/user/0
请问 “udev” 分区是做什么的,为何分出来了3G大小呢
