This bug is really not important. Just a little little typo. In baselayout-1.12.10-r4(r5) I found that typo in /lib/rcscript/net/system.sh. It is about the comment of function "system_pre_start". In the comment, the function name is miswritten as "system_post_start". That's all. :)
Not applicable to baselayout-2, and we're not fixing trivial stuff in baselayout-1 right now. Thanks for reporting anyway though :)
