This reverts commit 0a9e82b430, which didn't end
up fixing anything. The problem was elsewhere; namely, using
'operating-system-services' instead of 'operating-system-user-services'.
Attempting to use the 'nfs-service-type' as part of a computed
operating-system definition, the following exception would be thrown:
ice-9/boot-9.scm:1685:16: In procedure raise-exception:
ERROR:
1. &ambiguous-target-service-error:
service: #<<service> type: #<service-type rpcbind 7f7529853780> value: #<<rpcbind-configuration> rpcbind: #<package rpcbind@1.2.6 gnu/packages/onc-rpc.scm:87 7f75389e78f0> warm-start?: #t>>
target-type: #<service-type shepherd-root 7f7529396080>
2. &message: "more than one target service of type 'shepherd-root'"
The problem was that the rpcbind shepherd-service object was dynamically
instantiated every time the rpcbind-service-type would be called, causing
multiple objects in some situations, resulting in the above condition.
* gnu/services/nfs.scm (rpcbind-service-type): Refactor and adjust in a way to
extract...
(rpcbind-shepherd-service): ... this new procedure.
* gnu/services/nfs.scm (<nfs-configuration>)[nfsd-tcp?, nfsd-udp?]: New
fields.
(nfs-shepherd-services)[rpc.nfsd]: Populate the --{no-,}tcp and --{no-,}udp
command line options based on the values of the nfsd-tcp? and nfsd-upd?
fields.
* doc/guix.texi (Network File System): Add doc.
Instead of accepting a string for just one protocol version accept a list of
supported versions.
* gnu/services/nfs.scm (<nfs-configuration>)[nfs-version]: Remove field and
replace...
[nfs-versions]: ...with this new field.
(nfs-shepherd-services): Pass as many "--nfs-version" options as there are
supported versions.
* doc/guix.texi (Network File System): Document nfs-versions.
Fixes <https://bugs.gnu.org/39708>.
Shepherd doesn't keep track of processes that fork themselves and would
disable the process after restarting it a couple times.
* gnu/services/nfs.scm (nfs-shepherd-services): Invoke rpc.mountd with the
'--foreground' option.
* gnu/services/nfs.scm (<idmap-configuration>)[verbosity]: New field.
(idmap-configuration-verbosity): New procedure.
(idmap-service-type): Use it.
* doc/guix.texi (Network File System): Document it.
* gnu/services/nfs.scm (<gss-configuration>, <idmap-configuration>): Fix
indentation.
(<idmap-configuration>): Rename accessor for NFS-UTILS field to
IDMAP-CONFIGURATION-NFS-UTILS.
(idmap-service-type): Use IDMAP-CONFIGURATION-NFS-UTILS.
* gnu/services/nfs.scm (pipefs-service-type): New variable,
(gss-service-type): New variable, (idmap-service-type) New variable.
* doc/guix.texi (Network File System): New node.
