----------------------------
-1. Kill --squash-rino-perm and --nosquash-rino-perm parameters of mkfs.ubifs.
-
-Originally, mkfs.ubifs did not have these parameters, and it always set
-permissions for the UBIFS root inode to be {uid=gid=root, u+rwx,go+rx}. This was
-a bug which was found too late, when mkfs.ubifs had already been used in
-production. To fix this bug, 2 new options were introduced:
---squash-rino-perm which preserves the old behavior and --nosquash-rino-perm
-which makes mkfs.ubifs use the right permissions for the root
-inode.
-
-For a while (releases 1.4.0-1.4.3) --squash-rino-perm was the default, and if
-neither --squash-rino-perm nor --nosquash-rino-perm were used,
-mkfs.ubifs printed a warning. This was introduced in mtd-utils-1.4.0 (13 Sep 2010).
-
-Now we have removed a warning and made --nosquash-rino-perm to be the
-default. Also, both options are declared deprecated, so users should try
-to stop using them.
-
-The further step is to remove both of them.
