Public bug reported:
as i see, ubuntu live cd system is almost same as the installed system.
some differences are: other user name; other locale; gparted is not
installed; bunch of some restricted software like mp3 is selected to
install or not; gui language is selected; separate mount points and file
systems for directories can be used upon installation. i usually use
just one "/" partition and one swap and ext4 filesystem... as i know
every package is copied, uncompressed and configured separately during
installation. as i know, copying a partition (a whole file system) with
dd is several times faster than copying data file by file, because disk
head has not to move much. so, maybe you could just copy the whole file
system of the running live cd, and then do some changes like renaming
user, changing password, removing or installing mp3 etc, installing
translation packages. i have now understood, that live cd filesystem is
squashfs, it is different from ext4. but, i will report this "bug"
anyway. maybe on the fly conversion from squashfs to ext4 is possible,
or modify squashfs and get ext4 inside of squashfs. as i know,
difference of ext4 file system depending on partition size is quite
small, and file system can be growed quite fastly.
