- The current draft of the POSIX user portability extensions spec says
- that df and du should give sizes in units of 512 bytes. I have found
- this behavior confusing and inconvenient; I suspect others do too.
-
- Some other people involved in the standards process have said they
- prefer units of 1024; in response, the committee added the -k option,
- which says to use 1024 instead of 512.
-
- I think this is not a real solution. The use of 512 as the unit will
- make life difficult for beginning users who don't know about -k. And
- it seems silly to make 512 the default if users won't like it.
-
- The committee chose 512, not because they think users prefer it,
- but for totally unrelated reasons having to do with how BSD and
- System V behave. I think this decision should be made based on the
- preferences of actual users. If the users tell the committee what
- they want, the committee may yet listen.
-
- Aside from that, we can make the GNU system do what users prefer even
- if that disagrees with POSIX. We don't have to follow the standard.
-
- But what do most users prefer? To find out, here is a poll.
-
-
- Which of these two alternatives would you prefer, and how much?
-
- * df and du output is in units of 1024.
-
- * df and du is in units of 512 unless you use -k.

- hlj@posix.com is included in the reply-to field of this message
- because he is the person to whom people not in the POSIX UPE committee
- should send their comments on the spec. It's important to send your
- preference to him, because the committee must then officially
- recognize that they know what you prefer. And they have to pay at
- least a little attention to your preference. I invited him to set up
- an alternative mailbox for these messages, but he said he'd rather get
- them in his own mailbox.
-
- I hope he gets a lot of mail. :-)
