- Assigning drive _letters_ *is* a DOS anachronism (inherited from CP/M)
- and even DOS refers to drives by drive number internally doesn't it?
- Also, Linux reports drives by number at boot-time.
-
- : origins of the 'should' which you cite. This question has been discussed

- : believe Linux must do everything the way BSD does prefer the numbered
- : drives, but there are important advantages to doing it the other way
- : round; for example, Linux allows many more partitions on a disk than
- : BSD does.
-
- I was not aware of the discussions on the Linux standards list because
- I don't read it. I suspect lots of other people reading comp.os.linux
- don't read the list either.
-
- : A further consideration is this: virtually all Linux systems currently
- : installed use /dev/hda and /dev/hdb for the drive devices; even SCSI
- : systems which don't have hardware corresponding to /dev/hda have the
- : device in the /dev directory.
-
- so use links during a changeover period, then drop the old names.
-
- : If you wish to continue this discussion, you might do so on the
- : list linux-standards@banjo.concert.net; I wouldn't mind arguing
-
- Is the fate of comp.os.linux to go the same way as comp.os.minix where
- all the interesting discussions migrated to the beta-testers mailing
- list and no-one outside that group knew what was happening to Minix?
-
- : against your view in E-mail either. But please don't publish
- : prejudices as absolute truths.
-
- Ouch!
-
- Fortunately, I have my asbestos underpants on today ;-)
-
- Other people responding to this thread have explained the BSD device
- naming conventions, so I won't. However, I would like to point out
- that it is the features that different Unix systems have in common that
- makes Unix an 'open' system - Please don't lose sight of that.
