Writing to ubifs

Writing to ubifs

[Patrick Schneider]

I have a use case where I would need to be able to manipulate the fstab on the rootfs before booting, so I wondered if it is possible to write to a mounted ubifs from barebox?
Currently I am trying with: 

mount /dev/nand0.root.ubi.rootfs /mnt/rootfs -o rw

which still yields in a readonly mount of the rootfs where I cannot manipulate files. Does barebox have write support to ubifs or is there another way?

Thanks for your answers!

Best regards,
Patrick

No, barebox does not have UBIFS write support. What are you trying to
archieve?
