IBM AS/400E Library File System (QSYS.LIB)

Read/Write Options
No matter what options the client specifies on the MOUNT command, some server
file systems from QOpenSys exist as read-only or read-write. However the client
mounts a file system determines how the file system is treated and how it functions
on the client.

Exporting and QSYS.LIB
Youcan export some .LIB and .FILE objects. If you export .SAVE files and a client
mounts them, then all attempts to open the files will fail. In general, you should
export only things that clients need access to.
All object types in the QSYS.LIB file system can be exported and mounted
successfully without error.All operations on exported and mounted file systems will
function as if the object existed locally on AS/400. For example, the only object
types in the QSYS.LIB file system that support all file input/output (I/O) operations
are database members (.MBR) and user spaces (.USRSPC).
If you export a QSYS.LIB file system directory and specify a network data file code
page, then OS/400 Network File System Support opens data files with the
O_TEXTDATA and O_CODEPAGE options.
