After installing a custom ROM on my Galaxy s i9000, the external_sd symlink is broken. So, I wanted to get this symlink back. I used the following code in Terminal Emulator (yes i am rooted with SuperUser):
su (superuser asked for rights, allowed) cd ./mnt/sdcard ln -s ./mnt/emmc external_sd
But I got a "Operation not permitted" error. How can i create the symlink now?
ROM: Onecosmic's ICS 4.0.3 rc1

external_sdis a mount point, not a symlink (hence it's a folder). You'd need to change how the ROM mounts it to go there instead of/mnt/emmc. – Matthew Read♦ Jan 4 '12 at 0:36
