=== NOT COVERED YET ===

These are not covered yet because the diff is not optimal for
them (they are placed on different location preventing from
direct in-document comparison):

imm
ipmilan
eps
idrac
ilo3
ilo4



=== RECAP ===

New fence agents (if I am not missing anything):

fence_emerson
fence_ilo3_ssh
fence_ilo4_ssh
fence_ilo_moonshot
fence_ilo_ssh
fence_mpath
fence_tripplite_snmp

re [comment 11]:

One important detail (even though rather implementation-specific)
with fence-agents is that there are plenty of duplicate files
(IIRC, used to be symlinks right away in the past, but this was
changed to accommodate situations where symlinking is not possible).

Let's have a look at the groups of such duplicates:

$ rpm -ql fence-agents | xargs -I{} sh -c 'test -d {} || ls -l {}' \
  | cut "-d " -f5,9 | grep '/usr/sbin/fence_' | sort | \
  { m=0; prev_s=0; prev_f=/dev/null; \
    while read s f; do \
      [ "$prev_s" -ne "$s" -o -n "$(diff -u "$prev_f" "$f")" ] \
      && { [ "$m" -eq 1 ] && echo -e "$prev_s;$prev_f\n"; m=0; } \
      || { echo "$prev_s;$prev_f"; m=1; }; \
      prev_s=$s; prev_f=$f; \
    done; }
> 2038;/usr/sbin/fence_ilo3_ssh
> 2038;/usr/sbin/fence_ilo4_ssh
> 2038;/usr/sbin/fence_ilo_ssh
> 
> 4313;/usr/sbin/fence_ilo
> 4313;/usr/sbin/fence_ilo2
> 
> 4800;/usr/sbin/fence_idrac
> 4800;/usr/sbin/fence_ilo3
> 4800;/usr/sbin/fence_ilo4
> 4800;/usr/sbin/fence_imm
> 4800;/usr/sbin/fence_ipmilan
> 
> 6568;/usr/sbin/fence_apc_snmp
> 6568;/usr/sbin/fence_tripplite_snmp

of which a first group, of fence_ilo*_ssh, and fence_tripplite_snmp
are the new agents.
