It is still point of discussion. I have arguments for 3 different options:
da - PRO: habitual CAM/SCSI disk name; CONTRA: ATA disk uses
completely separate ATA-native peripheral driver, it is difficult use
the same name for two drivers and it IMHO looks ugly:
ad - PRO: habitual ATA disk name; CONTRA: heavily conflicts with
ATA_STATIC_ID ata(4) option device unit numbering, also the same driver
name conflict, but a bit easier due to different parent bus;
ada - PRO: perfect from internal infrastructure PoV; CONTRA: just
unhabitual.
