Yes. I have 14 xen domains + 2 domUs and several services. Some of them
must run chrooted so I need to execute a script which compares
/chroot/boinc/etc /chroot/boinc/lib and so with their corresponding
files in /etc /lib and so. Thats the easy part. But having a hook
configurable in make.conf like this would maintaining the script easier:

PORTAGE_POST_EXECUTE="/root/bin/mychroottester.sh" should fire when
emerge is totally done.

I understand that I can have a /etc/portage/bashrc but
 
if [[ ${EBUILD_PHASE} == "postinst" ]]; then ...

would fire after each package emerged. Maybe having a variable to test
against which shows that the execution of portage is all done
would do it. So if the last package is emerged and installed
if [[ ${EBUILD_ALL_INSTALLED} == "true" ]]
then /root/bin/mychroottester.sh
fi
would give a fine hook to execute my script or email notifications with
"Software update done" messages and whatever one likes.

What do you think?

What is the right mail address and is the "sometimes lost email bug" on
both?
gentoo-user@l.g.o or gentoo-user@g.o ?
