Unlike Linux where (nearly) all Networkscards are named eth and all Harddisks are named hd.. BSD names every device after it’s device driver. I like this behaviour, because you don’t get unexpected results, if you load the modules in the wrong order.
\nUnfortunately there are now so many device drivers, that we are running out of letters, and conflicts happen, e.g. ct0 device is either a “WD33C93[ABC] based CBUS SCSI host adapter driver” found in japanese PC98 or a “Cronyx Tau WAN adapter”, a strange hardware from Russia.
\nToday I found another conflict, ar0 is either an ATA RAID device node or a
\n“Digi\/Arnet device driver” for another strange PPP\/HDLC Adapter.
\nThe greatest problem these conflicts cause, man pages have to have unique names. The ct-conflict was resolved by renaming the Cronyx driver to ctau in CURRENT, but the ar problem is difficult as the Arnet driver is unmaintained (== nobody wants to rename it) and the ATA maintainer is a dangerous axe-wearing Dane. I proposed that the ar.4 link is pointing to the Arnet driver on i386 and to the ATA Raid manpage on !i386.<\/p>\n","protected":false},"excerpt":{"rendered":"
