Pop fails custom install from recovery partition. about distinst

[mmstick]

I believe that's because squashfs fails if any files already exists where it's extracting.

unsquashfs doesn't fail if it finds duplicate files when -f is set, which is the case for Distinst (it also returns exit status 1 when it's not set).

I'm having the same issue when using the CLI to manually configure partitions for Vanilla OS, but the command doesn't return exit status 2 if ran via terminal, and it only happens when using the -u parameter (as opposed to -n).

UPDATE: In our case, unsquashfs returns exit code 2 because it creates symlinks in the output filesystem, which according to the documentation causes it to return such exit status. I'm not sure about Pop OS recovery, but it should be safe to ignore non-fatal errors from unsquashfs.
