[systemd-devel] list-boots is incorrect, was: lost journal persistence

Could it be that all the boot ids are actually the same for some reason?
I had this issue in a container when systemd was reading boot_id from
`/proc/sys/kernel/random/boot_id` and since /proc was bind-mounted, boot_id
always was host's boot_id.

You can also run `journalctl -F _BOOT_ID` to see a set of all the boot ids
recorded in the journal (this must agree with `journalctl --list-boots`.
You can also add ` -o verbose` to see all the fields of records. Since you
say that the messages are actually stored in the journal, it might be
interesting to check their _BOOT_ID fields.
