the files copied to the chroot etc are executable

[agroszer]

everything under

ubuntu-chromebook-installer/profiles/default/system/etc
ubuntu-chromebook-installer/profiles/devices/acer-c720/system

and also what the script creates, like
/etc/hosts
/etc/resolv.conf
/etc/fstab

[agroszer]

usb sticks and sdcards most probably will have vfat, which will have executable set...

[eyecreate]

Are you saying every file is marked as executable?

[agroszer]

yes whatever gets copied from the USB stick definitely

I think also the ones you create in $tmp_dir, and copy later to the chroot, just because $tmp_dir is also on the USB stick which is vfat

[eyecreate]

Hm, might be how the transition from fat to ext is handled. Can you get me the list of file permissions for the files once they are in the chroot?

[agroszer]

Sorry, I did the install by "manually" doing the iso->tar.gz and using a previous version of your script.
Also reset the executable perms on the various files.
All in all I don't want to go back because I don't really have the time.

okay, stealing some logs from https://gist.github.com/mpmc/5668e9f23fa36bd81fcb

those files all get the executable perm

An idea would be to copy them first to e.g. /tmp/somefolder set there -x and copy after that to the chroot

[eyecreate]

I'll look into getting this dealt with.
