| Summary : OverlayFS layers manipulation tools
|
Description :
OverlayFS is the union filesystem provided by Linux kernel.
This program comes provides three tools:
* vacuum - remove duplicated files in upperdir where copy_up is done but the
file is not actually modified (see the sentence \"the copy_up may turn out to
be unnecessary\" in the Linux documentation). This may reduce the size of
upperdir without changing lowerdir or overlay.
* diff - show the list of actually changed files (the difference between overlay
and lowerdir). A file with its type changed (i.e. from symbolic link to
regular file) will shown as deleted then added, rather than modified.
Similarly, for a opaque directory in upperdir, the corresponding directory in
lowerdir (if exists) will be shown as entirely deleted, and a new directory
with the same name added. File permission/owner changes will be simply shown
as modified.
* merge - merge down the changes from upperdir to lowerdir. Unlike aubrsync for
AuFS which bypasses the union filesystem mechanism, overlayfs-utils emulates
the OverlayFS logic, which will be far more efficient. After this operation,
upperdir will be empty and lowerdir will be the same as original overlay.
* deref - copy changes from upperdir to uppernew while unfolding redirect
directories and metacopy regular files, so that new upperdir is compatible
with legacy overlayfs driver.
For safety reasons, vacuum and merge will not actually modify the filesystem,
but generate a shell script to do the changes instead.
