[gentoo-alt] [prefix] Different install and build path

[Dirk Heinrichs]

Hi,

I just found out about the prefixed portage project. Looks like it finally 
implements functionality I requested already two years ago. That's good 
news.

What I would like to know is the following: Would it be possible to build 
for one prefix, but install into another?

Background: This would be an ideal thing for installing (and distributing) 
software into the AFS filesystem tree. As you may know, AFS supports 
read-only replication, were ro replicas of a volume (if existing) are 
accessed with preference over rw replicas. However, the rw replica can 
always be accessed through the so called rw path, like

/afs/mydomain.com/myvolume  (ro)
/afs/.mydomain.com/myvolume (rw)

The other thing that would be needed to support this is to be able to run 
user defined actions at certain states, like in this case run "vos release" 
after each successful install to synchronize the ro with the rw replica.

Thanks...

	Dirk
