Note a file system which is significantly shrunk --- which tends to be
the case with resize2fs -M --- is going to have files fragmented which
will have performance implications. It's not clear to me what you are
trying to optimize for --- I assume you're just wanting to save on
download bandwidth so you want a highly compressed image?
You might want to consider using a raw qemu image, e.g:
e2image -Q /dev/sda1 /tmp/sda1.qcow
bzip /tmp/sda1.qcow # optional
which can then be unpacked via:
bunzip /tmp/sda1.qcow.bz2
e2image -r /dev/sda1.qcow /dev/sda1
You can of course also use qemu-img from the qemu package. e2image -Q
is a bit more efficient though since it will only include blocks which
are in use in the file system, where as qemu-img is not aware of the
underlying file system.
