[gentoo-user] /usr/portage/packages/Packages - what for?

[Helmut Jarausch]

Hi,

I have the impression that when rsync'ing /usr/portage/packages from
another machine (BINSERVER), 
emerge --update --newuse --deep --buildpkg @system @world
doesn't update packages which are upto-date on BINSERVER
but not upto-date on the local machine.

What's the role of the file
/usr/portage/packages/Packages

Many thanks for a hint,
Helmut.

Here it stores alotta info about the binary packages - for instance with what 
useflags they were compiled. This info is not in the archives, which only 
contain the files.

I guess irony can be pretty ironic sometimes.

No, informations about environment are included in tbz2 packages.
You can read man xpak for explanations.

IMHO, the /usr/portage/packages/Packages file is an index for the
package manager to avoid wasting time to open, parse and close each
tbz2 file.

And it's fetched by machines using a BINHOST, as obviously over HTTP it's not 
practical to fetch the packages themselves to get the environment info.

Does "emaint --fix binhost" help?

Many thanks, that looks great.
I'll test it next time.
