Description Harald Hoyer 2014-12-16 11:52:48 UTC

dracut has a symlink from /var/log to /run/log in the initramfs

Some programs e.g. systemd-journald expect a directory in /var/log as
the marker to do some actions. Here journald tries to flush
/run/log/journal to /var/log/journal, if the directory is seen.

Harald, does /var/log have to exist? IIUC, your patch fixes the problem by delaying the creation of the /var/log link, but it is still a race condition. If systemd-journald was restarted, then it'll see /var/log exists. It would be nicer to get rid of the symlink entirely.

/var/log does not point to /run/log now. That is the trick.

Because /run/log/journal existed, /var/log/journal also existed and thus journald was trying to flush to /var/log/journal.

/var/log now points to /run/initramfs/log, which is why it works now.
