This morning I did a cros clean --safe and it seems it has messed up my chroot somehow that I think emerge binary has been removed. Here I logged the result of some relating commands. I'm going to clobber the chroot and make a new one. But I think there might be something wrong with cros clean --safe.


I don't even have emerge binary anymore:
(cr) ((cca3cfe...)) ahassani@ahassani ~/trunk/src/scripts
$ emerge
-bash: emerge: command not found

So basically I cannot even do build packages. Note that I have tried both repo sync and update_depot_tools.
