Delay mounting of home directory?

I wonder if it is possible to delay mounting of a home directory?

Here is the background to the problem I am trying to solve:
I have two zfs disks, one rpool disk, and one zfs data disk. On the zfs data disk, I have data directories. In Solaris 11.3 there are default home directories on rpool, called Documents, Public, Downloads, etc. So I have deleted these home directories from rpool, and replaced them with symlinks. These symlinks points to the zfs data disk. So on the zfs data disk there are directories called Documents, Public, Downloads, etc. In my home directory, there are symlinks to these zfs data directories.

I also have a Linux Ubuntu partition. I have done the same thing on the Ubuntu partition. My home directory on the Ubuntu partition contains symlinks, pointing to the zfs data disk.

This means Ubuntu and Solaris shares the same data directories on the zfs data disk. I do not want to share the same home directory between Solaris and Linux, so I have not put the home directory on the zfs data disk. Because the configuration files differs from Solaris and Linux. Linux might use KDE, and Solaris might use Gnome. That will be a problem when I login if I share the same home directory between OSes. So Solaris and Linux home directories are not shared, but the data is shared via symlinks in Solaris and in Linux home directory. This way, I can work with the same data no matter which OS I boot from. I also have a VirtualBox VM data directory which I access from both Solaris and from Linux, so I can work with the same VM from both OSes, without the need to synching data.

Here is the problem. When I bootup Linux, I need to import the zfs data disk. Then I bootup Solaris instead, which makes Solaris complain because Solaris are trying to mount the home directory data folders, which points to the zfs data disk - which is mounted in Linux instead!

When I boot different OSes, I need to import the zfs disk. But then the other OS will complain because it can not mount the home directory. Is there a way to delay mounting of home directories? Then I can bootup an OS and import the zfs data disk, and after that I can manually mount the home directory.

EDIT: Adding "_netdev" in vfstab is the wrong track?

NAME

       amanda-applications - Application-api for amanda

DESCRIPTION

       Describe how to use application with Amanda

APPLICATIONS

       This section lists the applications included with Amanda. See the individual man pages for instructions on using them. For complete How-To
       information, consult the Amanda wiki at http://wiki.zmanda.com.

       o   amgtar(8), - use GNU Tar to backup and restore data.

       o   ampgsql(8), - use PostgreSQL's continuous WAL archiving.

       o   amraw(8), - use open and read to read the data.

       o   amsamba(8), - use smbclient to backup and restore data.

       o   amstar(8), - use star to backup and restore data.

       o   amsuntar(8), - use native tar on Solaris to backup and restore data.

       o   amzfs-sendrecv(8), - use zfs to create a snapshot and use 'zfs send' to generate the backup.

       o   amzfs-snapshot(8), - use zfs to create a snapshot and for use with other applications (e.g. amgtar)

DEFINING APPLICATIONS

       An application is defined in amanda.conf(5) as follows:

       define application-tool $appconfigname {
	  plugin "$pluginname"
	  property "$PROPERTY_NAME" "$PROPERTY_VALUE"
	  ...
       }
       and then referenced in a dumptype as

       define dumptype $dumptypename {
	  ...
	  program "APPLICATION"
	  application "$appconfigname"
       }

       Application properties, like Amanda configuration parameters, are insensitive to case, and - (dash) and _ (underscore) may be used
       interchangeably.

       See the individual plugin documentation for properties applicable to each plugin.
