pretty much any FreeBSD box...
>Description:
if you have a diskless machine and you don't want to stick pwd_mkdb on the machine... you can just manually make the new database files for the machine or you can now use vipw -d /diskless/machine/root/etc
hmm... just relized it would be nice to be able to turn off the passwd making.. plus allow you to keep the master.passwd in a different location :)
>How-To-Repeat:
vipw -d /diskless/machine/root/etc
returns the usage info
>Fix:
apply this patch (patch to do more of above to follow :) ):
