AFS is a special case (unless you meant AFP); it's mounted by the AFS cache manager when it's launched. Otherwise, per man diskarbitrationd
:
The file /etc/fstab
is consulted for user-defined mount points, indexed
by filesystem, in the mount point determination for a filesystem. Each
filesystem can be identified by its UUID or by its label, using the
constructs UUID
or LABEL
, respectively. For example:
UUID=DF000C7E-AE0C-3B15-B730-DFD2EF15CB91 /export ufs ro
UUID=FAB060E9-79F7-33FF-BE85-E1D3ABD3EDEA none hfs rw,noauto
LABEL=The\040Volume\040Name\040Is\040This none msdos ro
(Which makes me wonder when Apple gave up on deprecating /etc/fstab
.)
