[gentoo-dev] CONFIG_PROTECT and ROOT!='/'

[Vitaly Ivanov <im@rle.ru>]

Hello all

"To protect or not to protect..."

emerge tool overwrite files in CONFIG_PROTECT if ROOT != '/'

for example:
   CONFIG_PROTECT="/etc /opt/gentoos/hostname/root/etc"
   ROOT="/opt/gentoos/hostname/root/"
   emerge something
overwrite files in /opt/gentoos/hostname/root/etc

I found the comments of Nicholas Jones in bug 
http://bugs.gentoo.org/show_bug.cgi?id=52415

But if I really want to overwrite those files
I can do it by
CONFIG_PROTECT="-*"
ROOT="/opt/gentoos/hostname/root/"
emerge something

I can't chroot to /opt/gentoos/hostname/root and emerge there,
because it is cross compilation and I can't protect those files
in any way now.

May be protect *all* files in CONFIG_PROTECT
even if ROOT != '/'
This behavior can be easy override by CONFIG_PROTECT="-*"
in command line if needed.

Thanks.
