Description Ben Cotton 2020-10-20 20:51:32 UTC

This is a tracking bug for Change: Reduce installation media size by eliminating the intermediate EXT4 filesystem in the SquashFS
For more details, see: https://fedoraproject.org/wiki/Changes/OptimizeSquashFSOnDVDByRemovingEXT4FilesystemImageLayer

Change the process of building installation images such that the Squash filesystem image, which is present on netinstall and DVD ISO images, doesn't contain the EXT4 filesystem image. As a result of implementation of this change, files will be stored directly in SquashFS.

Mohan Boddu merged the request. The change will be included into the next Fedora RawHide nightly compose.

I'm not seeing this change in effect with Fedora-Workstation-Live-x86_64-34-20210213.n.0.iso

$ mount | grep ext4
/dev/mapper/live-rw on / type ext4 (rw,relatime,seclabel)

Reminder: The change complete (100% complete) deadline for Fedora 34 changes is Tuesday 23 February. At that point, changes should be 100% code complete, along with supporting documentation where appropriate. Please indicate this by setting the tracker bug for your change to ON_QA.

Hello,

Chris,
> I'm not seeing this change in effect with Fedora-Workstation-Live-x86_64-34-20210213.n.0.iso
I implemented the change only for DVD and netinstall images. Fedora Live ISO images are not covered since there is no support from Koji build system side. I'm updating summary of this bug report to make it clear.
You can try running the same command on DVD and you'll see the change.


Ben,
I this feature is ready and has been present in RawHide (Fedora 34) since end of October 2020. I documented this change earlier by submitting a pull request: https://pagure.io/fedora-docs/release-notes/pull-requests

I'm switching this bug report to ON_QA.

Kind regards,
Bohdan Khomutskyi
