This might be a pungi bug putting the ostree image in the wrong place. 

Adding lsedlar...

I did verify the images are identical.

The issue here is that both isos are created by running lorax. First lorax creates the boot.iso that is netinst, and Pungi hardlinks it in the iso/ directory with a pretty name.

Then the ostree one is created. It's actually put into a different location (under work/), but at the end the files are copied to the os/ directory and that overwrites what we had previously from creating the netinst.

This only happens in Workstation because that is the only variant that has both netinst and ostree installer isos.

I filed an upstream issue for this: https://pagure.io/pungi/issue/695

I actually noticed this a couple of weeks ago and tried to poke people on #fedora-releng about it, but no-one followed up.

It is not just boot.iso that's affected: it also (and in fact more importantly, since you can always get the actual netinst ISO from the main location for it) affects the os/images/ directory, which similarly seems to come from the OStree compose rather than the network install compose. The install.img from this directory is what gets downloaded and loaded into memory as stage2 when doing a PXE boot install (or other direct kernel boot install). This means anyone doing a PXE install from the Workstation tree at least wastes a bunch of bandwidth downloading an oversized file, and needs more RAM than they should to actually complete an install (as the file is loaded into RAM)...and I think it also means that anyone doing a PXE install from the Workstation tree ends up with an OStree install, which is very likely not what they wanted. (I haven't checked that for absolutely sure, though).

This bug appears to have been reported against 'rawhide' during the Fedora 27 development cycle.
Changing version to '27'.

Moving to proposed Beta blocker, as we're not doing an Alpha for F27.

Discussed during blocker review [1]:

punt (delay decision) - there was a general feeling in favour of this being a blocker, but it does not clearly violate any existing criteria. we're delaying the decision until there are more folks to help come up with a plan, including release engineering

Discussed during blocker review [1]:

punt (delay decision) - we did not yet get around to testing this in more detail or drafting a revised criterion, so we will punt (delay) this one again and try to get it done this week

The things we need is:
1) test the pxe case 
2) draft some kind of criterion this might actually break
3) see how releng feels about it and if the fix is short-term viable

Discussed during blocker review [1]:

drop nomination - the Workstation ostree installer image has never been built in an F27 compose; until it is, this bug cannot happen to one. So we're dropping the nomination for now, but will immediately re-nominate it if the bug does start affecting F27 composes

[1] https://meetbot-raw.fedoraproject.org/fedora-blocker-review/2017-09-11/

The compose configuration for Rawhide is updated to put the workstation ostree into a different location. Pungi got patched to not overwrite anything if the configuration wants that. Instead it will print an error message and abort (before actually doing anything). The patch is not yet released though.

And as of the 20170912.n.0 compose we're getting Workstation ostree installer images again, and the bug is back:

https://kojipkgs.fedoraproject.org/compose/branched/Fedora-27-20170912.n.0/compose/Workstation/x86_64/os/images/

note the size of boot.iso and install.img. So, I'm re-nominating this. We either need to disable compose of the Workstation ostree installer image till this is fixed, or just fix it ASAP.

This PR should fix it for F27 (the previous fix was only applied for Rawhide).

+1 to blocker

Discussed at 2017-09-14 Beta Go/No-Go meeting, acting as a blocker review meeting: https://meetbot-raw.fedoraproject.org/fedora-meeting-2/2017-09-14/f27-beta-go-no-go-meeting.2017-09-14-17.00.html . We were still undecided on whether this violates any criteria, but we're happy to grant it a freeze exception at least. A fix for it is pending and we're expecting the next compose to have it solved, so we'll check in on that and close the bug if so.

I just installed F26 Workstation from company PXE and got... F26 Workstation ostree system. So, it definitely affects PXE installations.

+1 Final blocker, in case it's not accepted as Beta blocker

Discussed at blocker review meeting [1]:

RejectedBlocker (Beta) AcceptedFreezeException (Beta) AcceptedBlocker (Final) - People can easily end up installing ostree edition instead of standard edition by accident, which breaks user expectations of how installation works

[1] https://meetbot-raw.fedoraproject.org/fedora-blocker-review/2017-09-18

This is clearly resolved in current F27 and Rawhide composes by the separation of the OSTree image into its own variant.
