Steps to Reproduce: 1.Start the rig 2.on grub menu, choose "Start boot loader from a read-only snapshot" 3.Choose one in the listed snapshots, #X 4.press enter on "Bootable snapshot #X"

You should not press enter on the title, you should select a boot entry. Most likely the second or third entry.

The first line is not a title: it's one in items of the list; however choosing an entry below the first does not change the result: it does not boot.

Sorry but the first entry is used to display the snapshot number and not used for booting, because people may need to know what the snapshot this menu belongs to and currently no good means in boot menu for displaying that, so that we carry first menu entry title to display it until a good solution can be found.

The second or third are your snapshotted boot (menu)entry, what's the error message that it does not boot ?

I red again my post, I did not want to criticize in any way, I'm sorry if it sound rude - however I think that the first item could be more explicative, kind of "don't choose me, choose one in the list below" :-).

I think we have to consider it, thanks.

You are not the first one reported that attempting to boot first entry is unbootable. I think we should try to improve it to be less confused. Besides it adds unwanted side effects in shifting the default entries in snapshotted grub.cfg if 'number' is used to index the entries. The proposed solution would be to use grub theme's label, but it lacks the ability to display text at run time so that requires patching grub2. And also it's not available in naked or text based menu without theme.

Another one would be to specifically handle first entry named the title 'bootable snapshot #..' to separate it from others, made it not counted as valid thus skipped and unselectable. but that's also ugly imho.

...

I split my answer in two parts.

First, as I wrote, there was no way to boot whichever entry I chose, and I got no error - just a black screen in case of second entry.

It could also be an issue from X, booting to text mode usually works for me.

...

Second, it looks like the last grub fixed the issue, I mean grub2 2.02~beta2-55.1.

I'm going to fresh net install the system, in order to clean up messy things around. I'll be reporting back as soon as I've test booting from snapshot on the fresh installed system.

Thanks and waiting for your result.

I tested it twice on my fresh install: it worked in both tests. In the second one, it hung on Plymouth splash screen, I switched to console mode (alt+tab) and I saw a message "waiting for starting job 1m35s", after 1m35s it booted. I guess it's something Plymouth related. Let me note that in addition of looking exactly like a menu entry, the line with "Bootable snapshot #X" has also the time count down and the automatic boot at the end.

I suspect that , for whatever reason, no profile for snapper was created during installation. (When I went into snapper for the first time it told me that 'no profile exists. You need to create a profile... etc') After creation of a profile it showed the above options. Can we trace this somehow?

Did your btrfs root partition more than 20 GB or such ? The btrfs snapshot requires enough size to be enabled by default for new installation. Thanks. -- You are receiving this mail because: You are on the CC list for the bug.
