Why?

In short, there is no way to do this - this is what DUIDs are for. > On 15.08.2014 11:51, Daniel Jakots wrote: > > On Fri, 15 Aug 2014 11:37:56 +0400, Denis Lapshin <[email protected]> > > > > wrote: > >> Is it possible to change or set fixed device names for drives like > >> SD0, SD1, SD2, SD3 and so on. > > > > http://www.openbsd.org/faq/faq14.html#DUID > > > > > > Cheers, -- "Action without study is fatal.
