MOUNT(1M) UNIX Programmer's Manual MOUNT(1M)
mount, umount - mount and dismount file system
/etc/mount [ special name [ -r ] ]
_M_o_u_n_t announces to the system that a removable file system is present on the device _s_p_e_c_i_a_l. The file _n_a_m_e must exist already; it must be a directory (unless the root of the mounted file system is not a directory). It becomes the name of the newly mounted root. The optional last argument indicates that the file system is to be mounted read-only.
_U_m_o_u_n_t announces to the system that the removable file sys- tem previously mounted on device _s_p_e_c_i_a_l is to be removed.
These commands maintain a table of mounted devices. If invoked without an argument, _m_o_u_n_t prints the table.
Physically write-protected and magnetic tape file systems must be mounted read-only or errors will occur when access times are updated, whether or not any explicit write is attempted.
/etc/mtab mount table
Mounting file systems full of garbage will crash the system. Mounting a root directory on a non-directory makes some apparently good pathnames invalid.
