* g13/g13.c (oNoMount): New. (opts): Add --no-mount. (main): Implement this. * g13/g13-common.h (opt): Add field no_mount. * common/status.h (STATUS_PLAINDEV): New. * g13/sh-cmd.c (has_option): Uncomment. (cmd_mount): Add option --no-mount and pass down. * g13/sh-dmcrypt.c (sh_dmcrypt_mount_container): Add arg nomount and emit PLAINDEV status line. (sh_dmcrypt_umount_container): Rund findmnt before umount. -- This option can be used to decrypt a device but not to mount it. For example to run fsck first. A command or option to run fsck before a mount will eventually be added. The use of findmnt is needed so that we can easily remove a device which has not been mounted.
