+You can run programs inside of the chroot by invoking the |
+"/usr/local/bin/${target%bit}" command. |
+ |
+This command can be used with arguments, in order to just run a single |
+program inside of the chroot environment (e.g. "${target%bit} make chrome") |
+or without arguments, in order to run an interactive shell session inside |
+of the chroot environment. |
+ |
+If you need to run things as "root", you can use "sudo" (e.g. try |
+"sudo ${target%bit} apt-get update"). |
+ |
+Your home directory is shared between the host and the chroot. But I |
+configured "${HOME}/chroot" to be private to the chroot environment. |
+You can use it for files that need to differ between environments. This |
+would be a good place to store binaries that you have built from your |
+source files. |
+ |
+For Chrome, this probably means you want to make your "out" directory a |
+symbolic link that points somewhere inside of "${HOME}/chroot". |
+ |
+You still need to run "gclient runhooks" whenever you switch from building |
+outside of the chroot to inside of the chroot. But you will find that you |
+don't have to repeatedly erase and then completely rebuild all your object |
+and binary files. |
