Currently such inconsistency can only be fixed manually, however for special objects like ROOT, it should be able to be repaird automatically. This can be achieved by checking special object LMA during the early mount-time scan, and checking if the subdirectories under <tt>ROOT/</tt> have a <tt>trusted.link</tt> entry matching <tt>fid_is_root()</tt>, or all have the same "<tt>..</tt>" FID, in which case the LMA FID is wrong (probably an IGIF FID) and should be fixed to use <tt><span class="error">&#91;FID_SEQ_ROOT:FID_OID_ROOT:0x0&#93;</span></tt>, rather than the IGIF FID.</p> LU-14365
