%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.
