Description of problem: If you use a command such as 'tar-in' (or 'tgz-in') and upload more data than you have available space, libguestfs hangs. Example reproducer: $ rm -f test.img $ truncate -s 10M test.img $ tar cf test.tar test.img $ ls -l test.{img,tar} -rw-rw-r--. 1 rjones rjones 10485760 2010-04-07 20:46 test.img -rw-rw-r--. 1 rjones rjones 10496000 2010-04-07 20:46 test.tar $ guestfish -a test.img \ run : mkfs ext3 /dev/sda : mount /dev/sda / : tar-in test.tar / [hangs] To see what's going on, add the -v option to the above guestfish command.
