Hello, the Kali live image contains PostgreSQL and with our latest image[1] PostgreSQL is no longer able to create a new database (/ is an overlayfs merging a RO squashfs filesystem and an empty RW tmpfs). [1] http://cdimage.kali.org/kali-weekly/kali-linux-2017-W43-amd64.iso (if 404 look up the parent directory and pick the currently available weekly image) You get messages like this while running createdb: createdb: database creation failed: ERROR: checkpoint request failed HINT: Consult recent messages in the server log for details. And in the server log you have this: ERROR: could not fsync file "pg_commit_ts": Invalid argument This was working with Linux 4.12.6 and seems to be broken in Linux 4.13.4 that we currently have in Kali Linux. Does this ring a bell to anyone ? I saw a few patches in 4.13.6 but their description does not seem to match the error I'm getting. What else can I provide to help you diagnose this issue ?
