Actually I just upgraded the xen "mother" to lenny, and xen 3.2, because 
I wasn't able to boot the lenny kernel on the domU. For now it seems to 
work fine.

BTW, the hires timestamps only work if the filesystem does support them,
and ext3 from lenny doesn't, but xfs does, and probably also ext4.

Is the windows ACL support in vfs_acl_xattr supposed to work in 3.5, or 
is it still considered experimental. Are people using it in production 
servers?

many thanks,
