I'm thinking about using fileexists() to create a class before readfile() and
edit_line. For instance;
vars:
have_key::
"key[$(keys)]" string => readfile("$(keystore)/$(keys).pub", "1024");
classes:
any::
"have_key" expression => fileexists("$(keystore)/$(keys).pub");
files:
have_key::
"$(u_home)/.ssh/authorized_keys"
comment => "Add defined keys to the authorized_keys file",
create => "true",
perms => mog("0600", "$(u)", "$(u)"),
edit_line => append_if_no_line("$(key[$(keys)])");
I don't try the code, but I think it should get rid of null value in $(key).
Cheers,
