The only good way would be a "mount --union" supported by the kernel -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I you rewrite/complete the patch according to this I will commit it to kiwi Thanks much for your help Regards, Marcus -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
