Never got a go-ahead. What I got was a complaint

that I wasn't normalizing, to which I posted a patch

and never got a response.

Yeah, conversation kinda ended with that last patch.

=20

But that wouldn't have deterred me. 30+ days of

silence is equivalent to acceptance -- just that I

had noticed that the patch could be expanded to

include mdconfig{,2} scripts. Was going to wait a

full day to see if anyone balked at the expansion

to include mdconfig{,2} and then move forward.

=20

Happy to move forward now that it appears that

general opinion is acceptance (and not by silence).

Has any of this been committed this far? I seem to recall mention of a go-a=
head but unsure.

get_if_var() normalizes IF part in the variable name before eval:

=20

|       _if=3D$1

|       _punct=3D". - / +"

|       for _punct_c in $_punct; do

|               _if=3D`ltr ${_if} ${_punct_c} '_'`

|       done

=20

while list_vars ifconfig_${_if}_alias[0-9]\* does not.

=20

I think this breaks the following configuration, for example:

=20

ifconfig_bge0_name=3D"ext.1"

ifconfig_ext_1=3D"inet 192.168.0.1/24"

ifconfig_ext_1_alias0=3D"inet 192.168.1.1/24"

=20

=20

Thanks! Didn't know about that feature. I've attached an updated patch for

review which takes this normalization into account


I was noticing /etc/rc.d/mdconfig and /etc/rc.d/mdconfig2 exhibit the same
behavior, so I've attached a new patch. I didn't find any other instances
where a break in the count would stop the loop prematurely.

No changes to the old patch, just added mdconfig{,2} to it.
