Thanks. It's nice that there is a writeup. But are non-technical people
expected to do this fix? (This is a rhetorical question to all of fedora-
devel.) Could dnf system-upgrade detect that it's running on a system that
will fail? Could it warn people beforehand or even apply the grub upgrade
first?
I have to think the issue could be detected before upgrading.
d=`mount | awk '$3 == "\/boot" { print $1 }' 2>/dev/null`
if [ "x$d" == "x" ] ; then
d=`mount | awk '$3 == "\/" { print $1 }' 2>/dev/null`
if [ "x$d" == "x" ] ; then
echo "Upgrading your grub2 install to a current version
cannot be done. You should not proceed with upgrading your system."
exit 1
fi
grub2-install $s
if [ $? -ne 0 ] ; then
echo "grub2-install encountered an error. You should not
proceed with upgrading your system."
exit 1
fi
fi
...
Anyways...following the instruction on that page...when
configfile /grub2/grub.cfg.rpmsave
is run, it immediately shows me the menu and boot commences as it did. It
then says: "execute the grub2-install /dev/X command (where X is the boot
device, i.e sda) to update the GRUB core and the module"
This is what happens:
# mount | grep boot
/dev/sda1 on /boot type ext4 (rw,relatime,seclabel)
[root ~]# grub2-install /dev/sda1
Installing for i386-pc platform.
grub2-install: warning: File system `ext2' doesn't support embedding.
grub2-install: warning: Embedding is not possible. GRUB can only be
installed in this setup by using blocklists. However, blocklists are
UNRELIABLE and their use is discouraged..
grub2-install: error: will not proceed with blocklists.
and rebooting the system now has:
grub rescue>
Which seems like a big step back from where I was.
