Re: [Libguestfs] nbdkit build failure in Koji

One thing I noticed which is a bit odd is: $ rm file; for f in {0..1023}; do printf '%1024s' .; done > file; stat -c "%b %B" file 2048 512 $ rm file; for f in {0..1023}; do printf '%1024s' . >> file; done ; stat -c "%b %B" file 3968 512 The second method is how we currently create the file. Since looking through the history there seems to be no reason for that I'm going to push a commit which changes file creation to the first method, and it may be slightly faster too. However it makes me wonder if the file is not laid out in a single extent and if that might be causing our problems. Being only able to reproduce this on Koji makes a bit tedious to test theories :-(
