The
packrootfs
script currently lacks a check for whethercpio
is installed. Which leads to an insidious bug down the line where errors from unsuccessfully executingcpio
does not bubble up from the subshell on line 100. So the script returns 0 and allow other build steps to continue even though the rootfs have not been repackaged correctly with the desired init script and user-level program.This manifests as the guest booting with the original rootfs instead of the repackaged one.
I've been able to reproduce this bug reliably on
bash
andzsh
.
