People,
I want to enlarge my root partition on a Fedora 23 x86_64 system
and I know
I can boot on a LiveUSB stick and use [g]parted from there to do
what I want
but I thought I would try creating a small partition with the ISO
and its
contents in it to see if I could do what I want without needing to
use the
USB stick.
Since this is an end user support question, rather than a patch or
discussion about developing grub, it should be posted to
[email protected] rather than grub-devel. I have CC'd helo-grub. In
your replies, please include help-grub and *remove* grub-devel from
any further replies. This problem is also actually more Fedora
specific than grub related, as explained below.
The contents of /dev/sda6 is:

dr-xr-xr-x 2 root root 4096 May 22 05:05 LiveOS

I have made a little progress but I still can't get a boot - here
is the
current state of the relevant section of my grub2.cfg (I have been
trying
various changes):
menuentry "Fedora 22 XFCE ISO Boot (x86_64 bit)" {
insmod part_gpt
set isoname="Fedora-Live-Xfce-x86_64-22-3"
echo $isoname
set isofile="${isoname}.iso"
echo $isofile
loopback loop (hd0,gpt6)/$isofile
echo $loop
linux (loop)/isolinux/vmlinuz0 root=live:CDLABEL=${isoname}
rootfstype=auto ro rd.live.image rd.luks=0 rd.md [1]=0 rd.dm [2]=0
iso-scan/filename=${isofile}
iso-scan/filename= is a kernel parameter that Fedora does not
support,
as Fedora does not support loop booting (booting from the iso file
on
a filesystem rather than burned to a DVD or extracted to a hard
Is that a regression?
These links suggest that you can boot fedora from iso, with
iso-scan/filename.

Good to know!
drive). Please file a bug report against Fedora asking them to add
such support, or extract the iso (which you have also done already),
or use a distribution that supports loop booting such as Ubuntu. For
instructions on loop booting an Ubuntu iso (or any other iso which
ships with a loopback.cfg) please see

}
During the attempted boot I see the first two "echo"s but then get
messages
that "linux" and "initrd" commands do not exist . . is it
something simple I
am missing?
This is a Fedora specific problem, with upstream grub you would not
have this problem. I am not very familiar with Fedora's secure boot
setup, but I suspect that is the reason that the "linux" and
"initrd"
commands are not available, and that instead you need to use
"linuxefi" and "initrdefi".
That's probably it.
It was - and you were correct above - I simply added "efi" to both
commands and everything worked (I should have noticed that change
myself) . . I thought people here would like to know the result but I
will make sure I do "user" instead of "devel" next time . .
Thanks people,
Phil.
