it's a global config object (dictionary basically)

you can import values into it, which is what happens when the app is created
2016-06-14 16602, 2016

they are imported from config.py

do some debugging yourself
2016-06-14 16636, 2016
13:26 PM

so, the issue is that grub-reboot is for old grub (0.9x), but you're using grub 2.0. The correct command is "grub-editenv - set next_entry=4" where 4 is the index in crub.cfg of the kernel you want
2016-06-14 16653, 2016
13:26 PM
ruaok
ahhh!
2016-06-14 16600, 2016

grub loads the env file using its filesystem drivers and fails if it can't write to the file, iirc, which is why it can't be used on software raid or lvm
2016-06-14 16630, 2016
13:49 PM
kepstin
but plain ext4 should be ok, I think?
2016-06-14 16653, 2016

next_entry was reset, FWIW
2016-06-14 16631, 2016

hmm. does the kernel file /boot/vmlinuz-3.13.0-88-generic actually exist on the system?

13:51 PM
ruaok
2016-06-14 16629, 2016
13:52 PM

cause if the env file is used - and it is, if the next_entry was reset - the only thing I can think of for it not using that entry is that it fails to load for some reason and falls back :/

2016-06-14 16616, 2016

so, you *can* manually edit the /boot/grub/grub.cfg file if you understand that it'll get overwritten by update-grub later
2016-06-14 16617, 2016
13:54 PM
zas
we are still unsure about the correct syntax, is there a way to test it ?
2016-06-14 16637, 2016
13:54 PM
kepstin
you can rewrite it to remove the submenu, and re-arrange the kernel you want to the top
2016-06-14 16648, 2016
13:54 PM
ruaok
do we maybe need 1>1 and 1>7 ?
2016-06-14 16650, 2016
13:54 PM
kepstin
then it'll work even if the next_entry stuff is all broken
2016-06-14 16659, 2016
13:54 PM
kepstin
and update-grub will reset it back to the stock
2016-06-14 16605, 2016
13:56 PM
kepstin
just have to be careful not to put in any syntax errors tho, since then you'll just get a grub rescue prompt :/

2016-06-14 16659, 2016

^^ that should be the syntax to use for the variable, I think
2016-06-14 16609, 2016
13:58 PM
kepstin
looks like you can use either name or index
2016-06-14 16623, 2016
13:58 PM
ruaok
1>1 and 1>7 should work then?
2016-06-14 16628, 2016
13:59 PM

1>1 should be Ubuntu, with Linux 4.2.0-38-generic (recovery mode)
2016-06-14 16655, 2016
13:59 PM

i think 1>6 will be the 3.13 kernel
2016-06-14 16629, 2016

I guess grub-reboot should actually work with grub 2.0; it's a shell script or something that runs grub-editenv to update variables. might be distro-specific?
