In contrast to rdist, the online mirror daemon (omirrd) is - running all the time and transfers any changes on the file system as - soon as possible to all other servers. Symmetric means that all - servers have equal rights in changing a file: the last changer of a - file will win. This is the same behaviour as multiple processes - operating on a global file system. In effect, omirr can do the same - as NFS mounts, but will have better performance since the data is - stored on local disks. In contrast to a cache filesystem which has a - dedicated master copy, broken connections and/or servers are no - problem for continuing work on the remaining ones, because there is - no master copy. Every computer that wants to participate in the - mirroring needs to run the daemon omirrd, contained in the omirr - package which is available via FTP (user: anonymous) from - ftp://ftp.isa.de/pub/home/luik. You must say Y if you want to use - in.omirrd, but you should (but need not) say N if you don't (for - performance reasons). - - Note that this is experimental code; use at your own risk. - -Filename translation support -CONFIG_TRANS_NAMES - This is a useful feature if you have a pool of diskless Linux - clients which mount their root filesystems from a central - server. Depending on their hostnames, the clients can then see - different versions of certain files, which keeps maintenance at a - minimum when used for configuration files. The kernel running on the - clients should have this option enabled. If you don't administer a - pool of Linux clients, say N here, otherwise read on: - - When you say Y here, filenames, directory names etc become - context-sensitive. If you have a file named - "/etc/config#host=banana#", it will appear (by default) as - hardlinked to "/etc/config" on host "banana", while on host "mango" - another file "/etc/config#host=mango#" will appear as having been - hardlinked to "/etc/config". - This default behaviour can be changed by setting the _first_ - environment variable NAMETRANS to a colon-separated list of suffixes - which are tried in the specified order. For example, in - - 'env - NAMETRANS=#host=mango#:#ktype=diskless# "`env`" command ...' - - the command will see the same files as if it had been executed on - host "mango" with a diskless kernel. - - Using NAMETRANS supersedes _all_ default translations. Thus - translations can be completely switched off with an empty list, - e.g. - - 'env - NAMETRANS= "`env`" command ...' - - Note that some system utilities like tar, dump, restore should be - used with translation switched off, in order to avoid doubled space - in archive files and when extracting from them. Also, make sure that - nfsd, mountd (and similar ones like samba daemons) run without - translation, in order to avoid doubled (or even wrong) translation - at the server and at the client. - - You can automatically force the creation of context-dependent - filenames if there exists a template filename like - "/etc/mtab#host=CREATE#". As soon as a process running on "mango" - tries to create a file "/etc/mtab", the version - "/etc/mtab#host=mango#" is created instead (which appears in turn as - hardlinked to "/etc/mtab"). Note that if you want to make - "/etc/fstab" context-dependent, you should execute "touch - /etc/mtab#host=CREATE#" and "touch /etc/mtab.tmp#host=CREATE#", - because mount, umount and others running on different hosts would - otherwise try to create one shared /etc/mtab which would result in a - clash. Also one should execute "touch /etc/nologin#host=CREATE#" to - prevent global side effects from shutdown resp. runlevel. - - Please read Documentation/transname.txt if you intend to say Y here. - -Restrict translation to gid -CONFIG_TRANS_RESTRICT - If you say Y here, default filename translations are carried out - only if the parent directory of the context-sensitive file belongs - to a specific group id (gid). Trying to translate names everywhere - will decrease performance of file openings. Normally translations - are used only in system configuration files but not in ordinary user - file space. So you should change the gid of directories containing - context-dependent files to some special group like "adm" (group id - 4) and enable this option. As a result, users will not notice any - performance degradation resulting from filename translation. - - Note that translations resulting from the first environment variable - "NAMETRANS=..." are always carried out regardless of the gid of - directories. - - Beware: before turning on this option make sure that all directories - containing context-dependent files belong to the special group, or - system initialization may fail. If unsure, select N. - -Group id (gid) for translation restriction -CONFIG_TRANS_GID - Default name translations will be carried out only inside directories - belonging to the group id (gid) that you specify here. - Default is 4 (group "adm"). - -Nodename (hostname) translation -CONFIG_TR_NODENAME - Enables translation of name suffixes like in - "/etc/config#host=banana#".

If unsure, say Y. - -Kernelname translation -CONFIG_TR_KERNNAME - Enables translation of name suffixes like in - "/etc/config#kname=default#". The string is hard compiled into the - kernel by the following option. Useful if your kernel does not know - the hostname at boot time, and there is no way to tell the hostname - by lilo or bootp. Please avoid using this option and prefer - "Nodename (hostname) translation" (CONFIG_TR_NODENAME) wherever - possible. When mounting the root over NFS, the own hostname must be - known at boot time anyway; this option is just for special use. - Note that the default translations are tried in the order as - occurring in the configuration, that is 1) host 2) kname 3) ktype 4) - machine 5) system. If unsure, say Y. - -String for kernelname translation -CONFIG_KERNNAME - Enter the string you want to compile into the kernel. The string - will be used as context in context-dependent files like - "/etc/config#kname=#". - -Kerneltype translation -CONFIG_TR_KERNTYPE - Enables translation of name suffixes like in - "/etc/config#ktype=default#". The syntax is - #ktype=#. The string is hard compiled in the - kernel by the following option. Use if you want to create different - kernels with different behaviour. For example, use the string - "default" on your server, and use "diskless" on all your diskless - clients (and perhaps "dataless" on dataless clients). This way you - can avoid dozens of "config#host=# with same contents and - you have no effort when new machines are added. If unsure, say Y. - -String for kerneltype translation -CONFIG_KERNTYPE - Enter the string you want to compile into the kernel. The string - will be used as context in context-dependent files like - "/etc/config#ktype=default#". If your kernel is to be used on a - server, you probably can use "default" here. If your kernel is - intended for a diskless client, you probably should enter "diskless" - here. - -Machine type translation -CONFIG_TR_MACHINE - Enables translation of name suffixes like in - "/etc/config#machine=i486#". The syntax is - #machine=#. The machine types can be queried with the - command "uname -m". Normally used only on multi-architecture - installations. If unsure, say Y. - -System name translation -CONFIG_TR_SYSNAME - Enables translation of name suffixes like in - "/etc/config#system=Linux#". The syntax is - #system=#.
