 This has caught me out in the past. When it says gigabyte I expect 2^30
 bytes. Hopefully this time when I do an installation I will remember to get
 a calculator out. The people who don't care are mostly those who don't know
 what a gigabyte is.

(FTR, that's near to be insulting in my standards…)

I know what giga- and gibi-bytes are, but I still don't care right now; we are 
actually trying to get Wheezy out and there are other priorities (such as 572 
Release-Critical bugs) than this type of problem.

That said, I don't think anyone is trying to avoid a proper resolution of this 
bug. So the people who care mostly (and know what a gibibyte is) should start 
working on patches if they really want to get this fixed; this work will not 
come magically out of the blue.

Cheers,

I'm sorry, that was over the top.

Absolutely agreed. I wouldn't hope to see this fixed for Wheezy - even just
changing the wording of the text requires an enormous amount of work at this
stage - it's just frustrating to see it apparently being dismissed out of
hand as not being a problem.

Thanks,

Roger

Please have a look at IEC 60027-2 (or Wikipedia) to make clear that 
the wording is absolutely correct. So if anybody wants to change 
the units of measurement, a change to the wording _and_ the code 
is required.

I don't think anyone has suggested that the wording is wrong, just not what
is expected by many users. (Not that I agree with those standards, but
that's irrelevant.)

2012-08-07 Thread ian_bruce
 Severity set to 'wishlist' from 'important'

So if the partitioner invites people to specify their swap space, or any
other volume, in units of gigabytes, which JUST ABOUT EVERYBODY
understands to mean 2^30 in that context, and instead it uses the hard
disk manufacturers' phony units which are seven percent smaller, WITHOUT
EVEN TELLING YOU THIS, and you only find out when the installation is
complete, and nothing can be done about it except starting all over
again, then this isn't a real bug, but just wishlist?

Thanks for clearing that up.



quote from ls(1) man page:

--block-size=SIZE

scale sizes by SIZE before printing them. E.g., `--block-size=M'
prints sizes in units of 1,048,576 bytes. See SIZE format below.


quote from df(1) man page:

-B, --block-size=SIZE

scale sizes by SIZE before printing them. E.g., `-BM' prints
sizes in units of 1,048,576 bytes. See SIZE format below.


quote from du(1) man page:

-B, --block-size=SIZE

scale sizes by SIZE before printing them. E.g., `-BM' prints
sizes in units of 1,048,576 bytes. See SIZE format below.


[for all of the above, K=1024, M=1024^2, G=1024^3, T=1024^4]


quote from lvcreate(8) man page:

-L, --size LogicalVolumeSize[bBsSkKmMgGtTpPeE]

Gives the size to allocate for the new logical volume. A size
suffix of K for kilobytes, M for megabytes, G for gigabytes, T
for terabytes, P for petabytes or E for exabytes is optional. 
Default unit is megabytes.


[here it is considered so obvious that binary units are intended that
they don't even bother to mention it]

I think you probably have a strange definition of just about
everybody. In reality, I think that just about nobody cares about
gigabytes being 2^30, or 10. This is basically splitting
hairs, which wishlist perfectly fits.

Yes. Please don't shout.

$ bc  scale=6 ; (2^40) / (10^12)
1.099511

The difference between a binary and decimal terabyte is ten percent, or
one hundred gigabytes.

I would have thought that a lot of people would care about that, but
maybe I'm just strange.

$ bc  scale=6 ; (2^30) / (10^9)
1.073741

$ bc  scale=6 ; (2^20) / (10^6)
1.048576

Clearly the hard disk manufacturers care about differences of even five
and seven percent, or they wouldn't have been deliberately ripping
people off for decades.

This has caught me out in the past. When it says gigabyte I expect 2^30
