Re: Not enough space when building flash-images with new linux-firmware in build

[Adolf Belka <adolf.belka@ipfire.org>]

Hi All,

I have just noticed that there has been a lot of changes to the build process, including around the flash-images section.

So I am going to run a build with the latest next git status and see how the linux-firmware works with that.

No point investigating problems in a process that has been changed.

Regards,

Adolf.

After doing the rootfile update and modifications it successfully did the cdrom build step but then in the flash-images build it failed with not enough space and then all subsequent steps failed due to directories or files not being present due to not being able to create the directories with mkdir.
