* init_system_file_sd
*
* NTFS 1.2, 3.0, 3.1 - System files security decriptors
* =====================================================
*
* Create the security descriptor for system file number @sys_file_no and
* return a pointer to the descriptor.
*
* $MFT, $MFTMirr, $LogFile, $AttrDef, $Bitmap, $Boot, $BadClus, and $UpCase
* are the same.
*
* $Volume, $Quota, and system files 0xb-0xf are the same. They are almost the
* same as the above, the only difference being that the two SIDs present in
* the DACL grant GENERIC_WRITE and GENERIC_READ equivalent privileges while
* the above only grant GENERIC_READ equivalent privileges. (For some reason
* the flags for GENERIC_READ/GENERIC_WRITE are not set by NT4, even though
* the permissions are equivalent, so we comply.
*
* Root directory system file (".") is different altogether.
*
* The sd is returned in *@sd_val and has length *@sd_val_len.
*
* Do NOT free *@sd_val as it is static memory. This also means that you can
* only use *@sd_val until the next call to this function.
