Hello.

I´ve seen bin/165789: looks like this is my problem; however I thoght I´d ask, just to be sure.

# uname -v

bsdlabel: partition c doesn't cover the whole unit!
bsdlabel: An incorrect partition c may cause problems for standard system utilities


To me it looks like aacd1s1d covers whole aacd1s1.
Before I start populating this disk, is it safe?

 Bye & Thanks
        av.
