Workaround 2Gib file size limit by using compression and split

[SohamG]

Work around 2Gib release file limit as follows:

1. Tar gz the image
2. if the tar.gz is larger than 2GiB, use the linux split command, make multiple files. Add all files to release.
3. Otherwise, add tar.gz to release.

In case of 2, user would have to cat all the files in order to a single targz before extracting. We can provide a shell script for this.

A longer term solution is to host the ISO on some cloud object storage.

I'll go ahead and add a check to only split if its bigger than 2GiB

It seems to be doing the split but I don't see the second part of the iso in your example, only the first part with the “aa” suffix.

It seems to be doing the split but I don't see the second part of the iso in your example, only the first part with the “aa” suffix.

That's presumably because the approach here executes split with a 2GiB argument against the tarbar (under 2) rather than the initial iso (over 2), right?

Assuming this approach works fine, could it be done in tandem with either:
a) a script like this provided
b) generate a script like this as part of the build process to be included in a folder structure with the iso parts for easier execution by users?

cat guix-installer-$RELEASE_TAG.tar.gz-part* > guix-installer-$RELEASE_TAG.tar.gz-part.iso
