Creating a custom directory tree inside Xenstore

Is it possible to create a custom directory tree inside Xenstore using any of the Xenstore-utilities??
For example, "/local/domain/0/Customdir".

Thx,
Venkat

Try
#xenstore-write /local/domain/0/custom ""

It will create a key with no value in the dom0's xenstore tree.

Oh, my mistake, there is no such command. However, you don't actually need
to create directories explicitly. You can just write to e.g., /a/b/c and
directories a and b will be created automatically. Also there's really no
difference between a directory and a file, so you can e.g., 'xenstore-write
/a foo' and then even though /a contains data you can still create /a/b.

While Keir is right and you can put children in a node with data, it 
should be noted that the XenStore protocol suggests that you should not 
do this (i.e. a node should contain either data or children, but not both).

There is work being done on a new XenStore designed to fix the security 
and performance problems with the current version and this is one 
problem that is slated to be fixed.
