Re: [gentoo-user] most of /usr/portage gone--why? and what now}

[William Kenworthy]

If files have gone missing first step is fsck the disk just in case.
Next emerge sync if it works.  (dont use the fancy options until its
working again.)  Whats "esync" ??  I wouldnt trust it until you know
what happened.

You can copy the complete portage from another machine over the top
without problems - the rsync part of emerge does just that. If its not
to old, just change the profile link if necessary and emerge sync to
upgrade.

I upgrade portage as the first step after the sync whenever it appears:
portage upgrades often change some of the underlying structure (as well
as break things ...) 

There is also a rescue portage hidden somewhere in portage that can also
be downloaded - its a tarball of a basic portage with enough "bits" to
rescue a system thats lost its portage all together (I did this once
with rm -rf * in /usr/portage !)
