Description ram-z 2013-11-12 19:00:35 UTC 
$ journalctl --follow --since=-1day
will:
1. show the FIRST 10 lines of `journalctl --since=-1day`
2. wait for new entries 
3. print all the rest when a new entry is added to the journal

It's not really an issue, but kind of unexpected. I only noticed because I have an alias jc='journalctl --since=-1day'

Hmm, indeed. This is confusing. Note sure though what the right behaiour would be in this combination... Maybe just print an error?
Comment 2 ram-z 2014-02-21 15:17:22 UTC 
IMHO --follow should take precedence over --since because --since will show all entries starting at a specific date up until now, and --follow will print entries from now on.
Throw an error when mixing --follow and --until, since that doesn't make any sense.

With commit http://cgit.freedesktop.org/systemd/systemd/commit/?id=70af7b8ada --follow with --since first prints all lines that --since would print, and then follows.
