Package: systemd Version: 246.6-1 Severity: normal Systemd fails during an upgrade from buster to testing with an NFS mounted root filesystem. The issue appears to be that this filesystem doesn't support POSIX ACLs, which causes the postinst script to fail.
In this case, the NFS server is a Debian buster server running the standard Debian kernel. Setting up systemd-timesyncd (246.6-1) ...
