It does basically work; the ext4 snapshot is bloated because the tool doesn't understand uninitialized ext4 block groups, but that's just a detail. (But yes, I did test this). Because the tool was properly written to use libext2fs, ext4 should "just work" (modulo some little kinks like above). :) -Eric -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
