17 nohide This option is based on the option of the same name provided in IRIX
18 NFS. Normally, if a server exports two filesystems one of which is
19 mounted on the other, then the client will have to mount both filesystems
20 explicitly to get access to them. If it just mounts the parent, it will see
21 an empty directory at the place where the other filesystem is mounted. That
22 filesystem is "hidden".
23
24 Setting the nohide option on a filesystem causes it not to be hidden, and an
25 appropriately authorised client will be able to move from the parent to that
26 filesystem without noticing the change.
27
28 However, some NFS clients do not cope well with this situation as, for
29 instance, it is then possible for two files in the one apparent
30 filesystem to have the same inode number.
31
32 The nohide option is currently only effective on single host exports. It
33 does not work reliably with netgroup, subnet, or wildcard exports.
34
35 This option can be very useful in some situations, but it should be used with
36 due care, and only after confirming that the client system copes with the
37 situation effectively.
38
39 The option can be explicitly disabled with hide.
