1.787 +You can run programs inside of the chroot by invoking the

1.789 +
1.790 +This command can be used with arguments, in order to just run a single
1.791 +program inside of the chroot environment (e.g. "${target%bit} make chrome")
1.792 +or without arguments, in order to run an interactive shell session inside
1.793 +of the chroot environment.
1.794 +
1.795 +If you need to run things as "root", you can use "sudo" (e.g. try

1.797 +
1.798 +Your home directory is shared between the host and the chroot. But I
1.799 +configured "${HOME}/chroot" to be private to the chroot environment.
1.800 +You can use it for files that need to differ between environments. This
1.801 +would be a good place to store binaries that you have built from your
1.802 +source files.
1.803 +
1.804 +For Chrome, this probably means you want to make your "out" directory a
1.805 +symbolic link that points somewhere inside of "${HOME}/chroot".
1.806 +
1.807 +You still need to run "gclient runhooks" whenever you switch from building
1.808 +outside of the chroot to inside of the chroot. But you will find that you
1.809 +don't have to repeatedly erase and then completely rebuild all your object
1.810 +and binary files.
