Tentando configurar o perfil móvel para o usuário montando o compartilhamento de samba remoto usando pam_mount . No entanto, a opção nounix está sendo adicionada automaticamente na pasta montada, devido a quais links simbólicos não podem ser criados na pasta compartilhada, nem o programa csync pode ser usado para sincronização.

mount.cifs (8) tem as seguintes informações:
nounix
Disable the CIFS Unix Extensions for this mount. This can be useful in order to turn off multiple settings at once. This includes POSIX acls, POSIX locks,
POSIX paths, symlink support and retrieving uids/gids/mode from the server. This can also be useful to work around a bug in a server that supports Unix
Extensions.
See section INODE NUMBERS for more information.
Eu tentei adicionar unix à lista de opções de montagem, mas isso falha com:
mount error(22): Invalid argument
Nov 3 17:24:35 system lightdm: (mount.c:76): Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
Por que a opção nounix é adicionada automaticamente como ela pode ser desativada?
Como alternativa, posso saber quais são as opções exatas desativadas pelo nounix para que possam ser ativadas?
OS é o Ubuntu 16.04
$ uname -srm
Linux 4.10.0-38-lowlatency x86_64
Com a pasta já montada por pam_mount , se eu desmontar e depois remontá-lo, recebo o mesmo mount output.
No entanto, se eu desabilitar a pasta mount em pam_mount , efetue logout, login e tente montá-lo manualmente através da linha de comando, então em alguns casos não obtenho < em> nounix nas opções de montagem? (muito confuso; precisa identificar onde ele funciona e onde ele não funciona)
