# Otions for the amd parser within autofs.
|
|
#
|
|
# amd configuration options that are aren't used, haven't been
|
|
# implemented or have different behaviour within autofs.
|
|
#
|
|
# A number of the amd configuration options are not used by autofs,
|
|
# some because they are not relevant within autofs, some because
|
|
# they are done differently in autofs and others that are not yet
|
|
# implemented.
|
|
#
|
|
# Since "mount_type" is always autofs (because there's no user space
|
|
# NFS server) the configuration entries relating to that aren't used.
|
|
# Also, server availability is done differently within autofs so the
|
|
# options that relate to the amd server monitoring sub-system are
|
|
# also not used.
|
|
#
|
|
# These options are mount_type, auto_attrcache, portmap_program,
|
|
# nfs_vers_ping, nfs_allow_any_interface, nfs_allow_insecure_port,
|
|
# nfs_proto, nfs_retransmit_counter, nfs_retransmit_counter_udp,
|
|
# nfs_retransmit_counter_tcp, nfs_retransmit_counter_toplvl,
|
|
# nfs_retry_interval, nfs_retry_interval_udp, nfs_retry_interval_tcp,
|
|
# nfs_retry_interval_toplvl and nfs_vers.
|
|
#
|
|
#
|
|
# Other options that are not used within the autofs implementation:
|
|
#
|
|
# log_file, truncate_log - autofs used either stderr when running in
|
|
# the foreground or sends its output to syslog so an alternate
|
|
# log file (or truncating the log) can't be used.
|
|
#
|
|
# print_pid - there's no corresponding option for this within autofs.
|
|
#
|
|
# use_tcpwrappers, show_statfs_entries - there's no user space NFS
|
|
# server to control access to so this option isn't relevant.
|
|
# The show_statfs_entries can't be implemented for the same
|
|
# reason.
|
|
#
|
|
# debug_mtab_file - there's no user space NFS server and autofs
|
|
# avoids using file based mtab whenever possible.
|
|
#
|
|
# sun_map_syntax - obviously, are provided by autofs itself.
|
|
#
|
|
# plock, show_statfs_entries, preferred_amq_port - not supported.
|
|
#
|
|
# cache_duration, map_reload_interval, map_options - the map
|
|
# entry cache is continually updated and stale entries
|
|
# cleaned on re-load, which is done when map changes are
|
|
# detected so these configuration entries are not used
|
|
# by autofs.
|
|
#
|
|
# localhost_address - is not used within autofs. This
|
|
# configuration option was only used in the amd user
|
|
# space server code and is not relevant within autofs.
|
|
#
|
|
#
|
|
# Options that are handled differently within autofs:
|
|
#
|
|
# pid_file - must be given as a command line option on startup.
|
|
#
|
|
# print_version - program version and feature information is obtained
|
|
# by using the automount command line option "-V".
|
|
#
|
|
# debug_options, log_options - autofs has somewhat more limited
|
|
# logging and debug logging options. When the log_options
|
|
# options is encountered it is converted to the nearest
|
|
# matching autofs logging option. Since the configuration
|
|
# option debug_options would be handled the same way it
|
|
# is ignored.
|
|
#
|
|
# restart_mounts - has no sensible meaning within autofs because autofs
|
|
# always tries to re-connect to existing mounts. While this
|
|
# has its own set of problems not re-connecting to existing
|
|
# mounts always results in a non-functional automount tree if
|
|
# mounts were busy at the last shutdown (as is also the case
|
|
# with amd when using mount_type autofs).
|
|
#
|
|
# forced_unmounts - detaching mounts often causes serious problems
|
|
# for users of existing mounts. It is used by autofs in some
|
|
# cases, either at the explicit request of the user (with a
|
|
# command line or init option) and in some special cases during
|
|
# program operation but is avoided whenever possible.
|
|
#
|
|
#
|
|
# A number of configuration options are not yet implemented:
|
|
#
|
|
# fully_qualified_hosts - not yet implemented.
|
|
#
|
|
# unmount_on_exit - since autofs always tries to re-connect
|
|
# to mounts left mounted from a previous shutdown this
|
|
# is a sensible option to implement and that will be
|
|
# done.
|
|
#
|
|
# browsable_dirs - not yet implemented.
|
|
#
|
|
# exec_map_timeout - a timeout is not currently used for
|
|
# for program maps, might be implemented.
|
|
#
|
|
# tag - the tag option is not implemented within autofs.
|
|
#
|
|
#
|
|
# Supported options:
|
|
#
|
|
# arch, karch, os, osver - these options default to what is returned
|
|
# from uname(2) and can be overridden if required.
|
|
#
|
|
# full_os - has no default and must be set in the configuration
|
|
# if used in maps.
|
|
#
|
|
# cluster - if not set defaults to the host domain name. This option
|
|
# corresponds to the HP_UX cluster name (according to the amd
|
|
# source) and is probably not used in Linux but is set anyway.
|
|
#
|
|
# vendor - has a default value of "unknown", it must be set in the
|
|
# configuration if used in maps.
|
|
#
|
|
# auto_dir - is the base name of the mount tree used for external
|
|
# mounts that are sometimes needed by amd maps. Its default
|
|
# value is "/a".
|
|
#
|
|
# map_type - specifies the autofs map source, such as file, nis,
|
|
# ldap etc. and has no default value set.
|
|
#
|
|
# map_defaults - is used to override /defaults entries within maps
|
|
# and can be used to provide different defaults on specific
|
|
# machines without having to modify centrally managed maps.
|
|
# It is empty by default.
|
|
#
|
|
# search_path - colon seperated paths to search for maps that
|
|
# are not specified as a full path.
|
|
#
|
|
# dismount_interval - is equivalent to the autofs timeout option. It
|
|
# is only possible to use this with type "auto" mounts due
|
|
# to the way the autofs kernel module performs expiry. It
|
|
# takes its default value from the autofs internal default
|
|
# of 600 seconds.
|
|
#
|
|
# autofs_use_lofs - if set to "yes" autofs will attempt to use bind
|
|
# mounts for type "auto" when possible.
|
|
#
|
|
# nis_domain - allows setting of a domain name other than the system
|
|
# default.
|
|
#
|
|
# local_domain - is used to override (or set) the host domain name.
|
|
#
|
|
# normalize_hostnames - if set to "yes" then the contents of ${rhost}
|
|
# is translated in its official host name.
|
|
#
|
|
# domain_strip - if set to "yes" the domain name part of the host
|
|
# is strippped when normalizing hostnames. This can be useful
|
|
# when using of the same maps in a multiple domain environment.
|
|
#
|
|
# normalize_slashes - is set to "yes" by default and will collapse
|
|
# multiple unescaped occurrences of "/" to a single "/".
|
|
#
|
|
# selectors_in_defaults, selectors_on_default - has a default value
|
|
# of "no". If set to "yes" then any defaults entry will be
|
|
# checked for selectors to determine the values to be used.
|
|
# selectors_in_defaults is the preferred option to use.
|
|
#
|
|
# hesiod_base - the base name used for hesiod map sources.
|
|
#
|
|
# Additional configuration options added:
|
|
#
|
|
# linux_ufs_mount_type - set the default system filesystem type that's
|
|
# used for mount type ufs. There's no simple way to determine
|
|
# what the system default filesystem is and am-utils needs to
|
|
# be continually updated to do this and can easily get it wrong
|
|
# anyway.
