I do not understand which command would you want to run before ~/.gdbinit.
Real world ~/.gdbinit should only change settings or define new commands.

The idea is that this is not a "change" as 7.4 did not have -iex at all.
-iex/-ix is a new feature for 7.5 so I am trying to make it right before it
becomes a standard.

It can affect only commands/settings which have some influence on the loading
of inferior.  There are not so many of such settings.

Besides safe-path also "set debug-file-directory" and associated "set
sysroot", not sure which more commands, if any.

"set debug-file-directory" - if set in /etc/gdbinit or ~/.gdbinit - currently
also cannot be overriden by -iex.

[again]

auto-load general acceptance looks to be bad so far so I try to improve its
user visible interface as best as I can.

This is unrelated to Fedora.  If I looked at Fedora then I can say that the
current -iex/-ix is already an established standard and it cannot be changed
anymore.  I do track FSF gdb-7.5 release for this change.

I really do not understand meaning of this paragraph.  I specifically care
about FSF GDB release at this moment where the change in some way may
negatively affect F17 users where the current behavior is already deployed.

Still I do not think this change can anyhow negatively affect -iex use.
