Hi Michael,
but in this case the key name is not a static, they key is the sysctl
parameter, would it be possible to use a similar construct to the one in
the template? my vars for this use case and also some others are 6-10+
items, each item could be defined easily as follow
vars:
pana_sys_ctl:
net.ipv4.ip_local_port_range: 32768 610
net.ipv4.tcp_fin_timeout: 30
net.ipv4.tcp_keepalive_time: 1800
....
pana_mounts:
mnt1:
red: filer001:/disk1/vol1
blue:filer002:/disk1/vol3
......
if it is possible through some filters or massaging of the dictionary that
would be great.
kind regards
Walid
