i don't know what ebuild you're working on currently, but that output says your cwd is incorrect (outside of WORKDIR).  you can only write to files under WORKDIR and T.

The ebuild I am working on is:



The current ebuild code is :https://cs.corp.google.com/chromeos_public/src/overlays/project-moblab/chromeos-base/chromeos-bsp-moblab/chromeos-bsp-moblab-0.0.5.ebuild

The code is currently

    insinto /etc/sudoers.d
    echo "moblab ALL = NOPASSWD: ALL" > moblab-sudo-all
    echo "apache ALL = NOPASSWD: /sbin/reboot" > apache-reboot
    echo "apache ALL = NOPASSWD: /sbin/restart" > apache-restart
    echo "apache ALL = NOPASSWD: /sbin/start" > apache-start
    echo "apache ALL = NOPASSWD: /sbin/stop" > apache-stop
    echo "apache ALL = NOPASSWD: /usr/sbin/apache2" > apache-apache2
    echo "apache ALL = NOPASSWD: /usr/bin/update_engine_client" > apache-update

i suspect you've made changes to the ebuild relative to what's in the tree, and it's those changes that have broken assumptions in src_install (probably relative to what i mentioned in comment #1)

the ebuild, as written in the tree, has S=${WORKDIR} so src_install's cwd starts off (correctly) in that writable location

I have change the existing ebuild and will send a CL to you

S=${WORKDIR}  is not allowed in ebuilds that inherit from cros-workon

https://cs.corp.google.com/chromeos_public/src/third_party/chromiumos-overlay/eclass/cros-workon.eclass?rcl=ded33d80ebc6ee0916bf00c162b929acd210c722&l=395

Is there a doc/codelab on cros-workon ?  I do not want to keep having to take up your time asking you what the correct procedure is for such changes.

if you need scratch space to generate a file, use $T instead

alternatively, newins can install from stdin.
  echo "moblab ALL = NOPASSWD: ALL" | newins - moblab-sudo-all
