And persistence does not give space back.
Also a misunderstanding. See the newly revised livecd-iso-to-disk man
page,
https://github.com/rhinstaller/livecd-tools/blob/master/docs/livecd-iso-t...
The storage space of any files in the original root filesystem (inside the
SquashFS
compressed ext3fs.img file) is not
recover
able
upon deletion, but the storage space
for newly added
files, or changes stored in the overlay,
is
recoverable
.
The overlay space
is allocated once
as needed
, so
the dmsetup status report of
allocated sectors will not reflect the availability of space once used but
later deleted.
(The confusion was caused by an error in an earlier version of the man
page, where
the overlay was described as a write-once storage method instead of an
allocate-once
method. The current version corrects this.)
