The atftpd server package seems to be broken and could perhaps use an upgrade.
Issue description:
When you configure the server to allow tftp-writes, the files are typically written to the folder above the one specified. Example: setting /tftpboot as the destination results in the files landing in /. Destination /home/tftpboot > files go in /home.
When reading files, everything works ok. This is not an urgent problem (for me at least) but if an upgrade is made available, I volunteer to test it.
