I *never* logged in graphically as root. I also do not use the root account: at most some 'sudo' commands from time to time. In the previous comments I had the root shell because I wanted to show as easy as possible that the whole content of the '/root' is only one symbolic link (fe1417537ae0451abdb60c5df28fe825-runtime -> /tmp/pulse-PKdhtXMmr18n) in the .config/pulse. And this link is created before the zfs-mount service has a chance to mount the 'real' root folder.
OK, nevermind that, do you know any good way how to find out which process might be the culprit? Is there some place where I can look? or some pulseaudio related debug config that I can enable somewhere to trace what happens during system startup? Any hint or suggestion is greatly appreciated. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1884455 Title: pulseaudio creates /root/.config/pulse/ before zfs-mount.service can mount the /root dataset Status in pulseaudio package in Ubuntu: Incomplete Bug description: I use 'zfs' and have /root as its own dataset which is mounted during startup by 'zfs-mount.service'. At one of the latest upgrades, the 'zfsutils-linux' package failed to update because the service 'zfs-mount' service had an issue and could not mount the '/root' dataset because the '/root' directory was not empty (temporary solution was to rename /root and call 'zfs mount' again). Further investigation shows that everytime at startup, the /root directory is created before the 'zfs-mount.service' has a chance to mount the 'root' dataset. The culprit seems to be something pulseaudio related: the content of /root folder after startup is as follows: ----------------- root@minighost:~# tree -a /root . ├── .cache └── .config └── pulse └── fe1417537ae0451abdb60c5df28fe825-runtime -> /tmp/pulse-PKdhtXMmr18n 4 directories, 0 files root@minighost:~# ----------------- Extra details: - Ubuntu release: ----------------- root@minighost:~# lsb_release -rd Description: Ubuntu 20.04 LTS Release: 20.04 ----------------- - status of 'zfs-mount.service' is the following: ----------------- root@minighost:~# systemctl status zfs-mount ● zfs-mount.service - Mount ZFS filesystems Loaded: loaded (/lib/systemd/system/zfs-mount.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Sun 2020-06-21 12:56:08 CEST; 6h ago Docs: man:zfs(8) Process: 2062 ExecStart=/sbin/zfs mount -a (code=exited, status=1/FAILURE) Main PID: 2062 (code=exited, status=1/FAILURE) Jun 21 12:56:08 minighost systemd[1]: Starting Mount ZFS filesystems...
