2006/6/3, Bruno <[EMAIL PROTECTED]>:
I don't know if vhashify and friends of util-vserver keep some state of their
operations (like a DB of hashed files)

AFAIK they just store files in a directory tree with their sha1 hashes
as file names


What may be useful is e.g. an adjusted 'cp' tool that copies regular files as
hardlink to the reference and adds IUNLINK and IMMUTABLE flags to the
hardlinked files (where the flags are not alreay present)
This will copy a whole guest as quickly as scanning the existing tree and
creating a new inode/hardlink for each inode encountered.

A neat addition might be automatically differentiating between unified
files (hardlink them with cow flags) and normal files (copy them over)
so that copying an already vhashified vserver would be a single
command

Best regards,
Grzegorz Nosek
