Thank you Jlliagre,

This is immensely useful stuff. I really value your knowledge on this.

Symbolic links do not cross filesystem name space. I'm not sure to get "moving the files up to the global", they are already in the global zone (too), aren't they ?

I want to "share" files below the "zonepath" point, ie, residing in the local zone. (This is a full root zone if that's significant.)

I was considering moving the files to above the zonepath and then sharing them from there but then local zone users need to see them too. Hence a symbolic link (or a hard link since the local zone is not on its own fs) to get local zone users not to see the files missing.

This is a production box so I can't just reboot zones when i like just to test this.

As I said, I've seen in a number of places that sharing files below a zonepath can screw up the zone boot process but it doesn't say how.
I haven't comprehensively tested sharing such from the global zone and then trying to shutdown and reboot the local zone in case it does screw up. Hence the question to find out what the rest of the planet knows about this.

NAME

       zcons - Zone console device driver

DESCRIPTION

       The  zcons character driver exports the console for system zones. The driver is comprised of two "sides:" a master side with which applica-
       tions in the global zone communicate, and a slave side, which receives I/O from the master side. The slave side is available in the  global
       zones.

       Applications must not depend on the location of /dev or /devices entries exported by zcons. Inside a zone, the zcons slave  side is fronted
       by /dev/console and other console-related  symbolic links, which are used by applications that expect to write to the system console.

       The zcons driver is Sun Private, and may change in future releases.

FILES

       /dev/zcons/<zonename>/masterconsole

	   Global zone master side console for zone <zonename>.

       /dev/zcons/<zonename>/slaveconsole

	   Global zone slave side console for zone <zonename>.

       /dev/zconsole

	   Non-global zone console (slave side).
