necessarily mounted in the order listed in
Verbose mode.
Write a message to standard output indicating which
file system is being mounted.
Specify the CDFS file system type (see
fstyp(1M)).
Limit actions to local file systems only.
Specify options specific to the CDFS file system type.
specific_options is a list of comma separated subop‐
tions and/or keyword/attribute pairs intended for
the CDFS specific module of the command.
The following specific_options are valid on CDFS
