OK, let's try again, since Jordan obviously wasn't able to guess what your question means. No. Nothing compels us (or you personally) to use these names. I'm running CAM on my development machine (FWIW, vinum seems to work fine with CAM), and I still haven't changed the device nodes: === root@razzia (/dev/ttyp0) /usr/src 25 -> ls /dev/sa* ls: /dev/sa*: No such file or directory === root@razzia (/dev/ttyp0) /usr/src 26 -> ls /dev/sd* /dev/sd0 /dev/sd0s1f /dev/sd1s1b /dev/sd2e /dev/sd3a /dev/sd3s1g /dev/sd4s1c /dev/sd0a /dev/sd0s1g /dev/sd1s1c /dev/sd2f /dev/sd3b /dev/sd3s1h /dev/sd4s1d /dev/sd0b /dev/sd0s1h /dev/sd1s1d /dev/sd2g /dev/sd3c /dev/sd3s2 /dev/sd4s1e /dev/sd0c /dev/sd0s2 /dev/sd1s1e /dev/sd2h /dev/sd3d /dev/sd4 /dev/sd4s1f /dev/sd0d /dev/sd1 /dev/sd1s1f /dev/sd2s1 /dev/sd3e /dev/sd4a /dev/sd4s1g /dev/sd0e /dev/sd1a /dev/sd1s1g /dev/sd2s1a /dev/sd3f /dev/sd4b /dev/sd4s1h /dev/sd0f /dev/sd1b /dev/sd1s1h /dev/sd2s1b /dev/sd3g /dev/sd4c /dev/sd4s2 /dev/sd0g /dev/sd1c /dev/sd1s2 /dev/sd2s1c /dev/sd3h /dev/sd4d /dev/sd4s3 /dev/sd0h /dev/sd1d /dev/sd1s3 /dev/sd2s1d /dev/sd3s1 /dev/sd4e /dev/sd4s4 /dev/sd0s1 /dev/sd1e /dev/sd1s4 /dev/sd2s1e /dev/sd3s1a /dev/sd4f /dev/sd0s1a /dev/sd1f /dev/sd2 /dev/sd2s1f /dev/sd3s1b /dev/sd4g /dev/sd0s1b /dev/sd1g /dev/sd2a /dev/sd2s1g /dev/sd3s1c /dev/sd4h /dev/sd0s1c /dev/sd1h /dev/sd2b /dev/sd2s1h /dev/sd3s1d /dev/sd4s1 /dev/sd0s1d /dev/sd1s1 /dev/sd2c /dev/sd2s2 /dev/sd3s1e /dev/sd4s1a /dev/sd0s1e /dev/sd1s1a /dev/sd2d /dev/sd3 /dev/sd3s1f /dev/sd4s1b Did I guess the correct meaning of your question?
