MBR (PC BIOS) partition tables were historically maintained with
fdisk(8), but gpart(8) has long been the preferred method for working

obsolete in the man page since 2015. Similarly BSD disklabels were
historically maintained with bsdlabel. It does not yet have a
deprecation notice - I have proposed a man page addition in
https://reviews.freebsd.org/D43563.
man page additions are not going to reach the people who may be
using this. This should be a gonein(15) added to the binary.
I also suspect that all of the people doing ufs installs
are doing so via bsdlabel, not gpart.
I have many FreeBSD installations running in a UFS-based VM, created
using bsdinstall or manually using gpart. I haven't touched fdisk and
bsdlabel in at least a decade.
I would like to disconnect these from the build, and subsequently
remove them. This is prompted by a recent bsdlabel bug report which
uncovered a longstanding buffer overflow in that tool. Effort is much
better focused on contemporary, maintained tools rather than
investigating issues in deprecated ones. Removing these tools would
happen in FreeBSD 15 only (no change in 14 or 13).

How can you do bsdlabel -A -e /dev/foo with gpart? As far as I know
that functionality never made it to gpart, neither the -A or -e.
I was curious what this command does that is so special, but it seems to
be of no use anymore:
% bsdlabel -A /dev/ada0
bsdlabel: disks with more than 2^32-1 sectors are not supported
Do we really need a tool that can't handle disks of average size (in
this case 4TB)?
Kind regards
