I have sent a report to upstream developers of overlayfs: I got a query for more data: And I responded with the required data: |

In fact, this seems to be caused by the switch to PostgreSQL 10. The database server tries to fsync() a "pg_commit_ts" directory that has not been modified since the initial installation and this fails because overlayfs delegates the fsync() to the squashfs read-only filesystem that does not have this operation. I reported this to PostgreSQL developers: |

Now that the problem is understood I have added a work-around in kali-defaults 2017.3.2 where we touch a file in /var/lib/postgresql/10/main/pg_commit_ts/ and immediately drop it before starting postgresql. |

We have a fix in the kernel as well. So this issue can be closed. I dropped the work-around in git. |
