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.
The contents of /dev/sda6 is:
dr-xr-xr-x 3 root root 4096 May 22 05:03 EFI
dr-xr-xr-x 2 root root 4096 May 22 05:05 LiveOS
dr-xr-xr-x 2 root root 4096 May 22 05:03 isolinux
drwx------ 2 root root 16384 Nov 2 06:08 lost+found
-r--r--r-- 1 root root 2460 May 22 05:04 Fedora-Legal-README.txt
-rw-r----- 1 qemu qemu 1007681536 Oct 7 20:14 Fedora-Live-Xfce-x86_64-22-3.iso
-r--r--r-- 1 root root 1063 May 22 05:04 LICENSE
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=0 rd.dm=0 iso-scan/filename=${isofile}
initrd (loop)/isolinux/initrd0.img
}
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?
