May I ask,

If you are on minimal/server version, you need to mount it manually using mount command and the storage device will be on /dev/sda typically, so you can mount it like

$ mkdir 1
$ mount /dev/sda1 1
$ cd 1

you can check what devices are there through
$ ls /dev/ | grep sda

If you are on desktop, just check /run/media/khadas, it will be another subdirectory which is the disk name. again you can check devices as
$ ls /run/media/khadas

Thank you for your answer,！but no, you didn’t understand my intention.

I want to know, how can I configure the default insertion and removal of USB drives to automatically mount the directory name I defined, and where can I modify it?

I directly added/dev/sda1/media/usb0 ntfs defaults 0 0in/etc/fstab,but there was a problem where I didn’t insert a USB drive to start the system, and I saw that the log would start slowly

1.This method only works on fixed storage devices.
2.Try udev rules to automatically mount the USB disk.

sudo vim /etc/udev/rules.d/99-usbstick.rules

KERNEL=="sd[b-z][0-9]", SUBSYSTEMS=="usb", ACTION=="add", RUN+="/sbin/mount UUID=YOUR-UUID /media/xxx"

YOUR-UUID Obtain:
lsblk -f
blkid /dev/xxx

sudo systemctl restart udev

@ivan.li hi,
How to restrict static fixed uuids?
For example, if I create an IMG format image and want to mount it using a pre known UUID, how can I restrict the UUID from being fixed and unchanging

Burn the firmware to the storage device, the uuid value should not change.

@ivan.li hello,
I tested here and found that it changed. I made a userdata.img package and burned it in, and the uuid changed:

One. I have finished making it, and the uuid for it is:
userdata.img: UUID="89591460-c976-4a53-b530-0d0f66d12ccf" TYPE="ext2"
Two. I burned the system to view:
UUID="fe168cdc-0732-4e3d-84ff-f79524046fba"

So it’s different, how to restrict fixed uuids

If you format or partition the storage device, the uuid value will change.
