At initial creation people will still use whatever unit they care about,
whether it be GB, MB, or TB (or sectors). But they'll be specifying the units
Likely not even using the print function until the end and possibly not at all

This patch is not about creating however, it's about printing, which indicates
to "look back" at the partition structure. Whether admins are troubleshooting
a missing partition, a misaligned partition, the need will be to make
adjustments in sectors,
therefore the need will be to view the boundaries in sectors. The operating
system and the
software layers atop it (clustering & lvm for example) care about sectors and
so should we.
To have the precursory knowledge to know that one needs to manipulate a
also suggest the knowledge to know that the manipulation should be done in
else will bring unexpected results. The majority of users of this tool are
for servers, not desktop users (desktop users would likey use a gui tool)

The latest fdisk packages print in sectors by default. They do however, similar
to my patch proposal, provide the whole disk size in B, s, and some other user
friendly unit. My colleagues and I are all in linux storage support/maintenance
engineering; my claims regarding alignment with the needs of administration are
direct observation of everyday administration issues as seen by our customers.
>> Nobody thinks about what sector they want the partition to start and end on.
I'd argue the opposite, if someone is thinking about partition boundaries, they
would not be thinking about what MB boundary it falls on, at least not for long.
They'd realize quickly that they need sectors to have any certainty that the
changes they are making are correct.
For whole disk size the compact print is great, that's why I've included it in
but for boundary location printing, sectors should be used are are far more
Additionally, we should, as people providing/supporting these products/services
sector use, not steer users away from it.
