The recidive jail reads /var/log/fail2ban.log and this module ships the
logrotate file for it, but nothing ever told fail2ban to write there. Where
the package default stands, fail2ban logs to the journal, the recidive jail
finds no log file, and the whole service refuses to start -- taking the sshd
jail with it. Two machines assigned this module today came up failed; the two
where it worked had /etc/fail2ban/fail2ban.conf edited by hand, which a
package upgrade would have undone.
Declared in fail2ban.local, because fail2ban.conf belongs to the package.
