How I symlink external SDCard / MMC while using PROOT

[defencedog]

In order to use video cutter LosslessCut I have followed this tutorial to install udroid
#134

Now in the root I have automatically a folder name sdcard which is my internal storage; absolute location /sdcard Now i cannot find my MMC (memory card)

Poking around i found the HOME directory of termux located in this location /root/com.termux/files/home Previously i had symlinked my MMC location via ln -s /storage/28E1-1BF4/ mmc ...but the mmc folder is red (broken symlink) while in proot.

Any help will be appreciated

In Android, userspace apps don't have permission to create symlinks to any storage space except it's data folder cause of if it's policies.

In case of termux it's data folder is /data/data/com.termux/

When termux executes proot that process belongs to termux which is a normal app without su permissions so whatever symlink which are in current runtime that points out of /data/data/com.termux will be broken by Android policy and back in chroot you can access It ( cause root has access rights to all files )

Final thesis: You can just read & write files in external storages ( any operation like creating symbolic links ( ln -s ) or executing file from external storages just won't work in proot )

It depends on device vendor, some vendor create explicit rule for sdcard in selinux. So access to external storage depends on manufactoror.

It works on Samsung devices
