[gentoo-user] q-reinitialize script in portage-utils-0.10

Latest stable portage told me this:

 * Messages for package app-portage/portage-utils-0.10:

 * /etc/portage/postsync.d/q-reinitialize has been installed for convenience
 * If you wish for it to be automatically run at the end of every --sync:
 *    # chmod +x /etc/portage/postsync.d/q-reinitialize
 * Normally this should only take a few seconds to run but file systems
 * such as ext3 can take a lot longer.  To disable, simply do:
 *    # chmod -x /etc/portage/postsync.d/q-reinitialize

but it did not tell me *why* and I don't understand what "Reinitialize ebuild 
cache" mean.

In case this makes any odds, I am using eix.  Do I need the above script?

The q tool has it's own database. q-reinitialize updates it. It takes 
0.1 seconds to complete, so you can just activate it and forget about 
it. You can also execute it manually to see how fast it is.

Thanks Nikos, is this a database to be used by the q tools, or for some other 
purpose?

I am trying to understand if I will be duplicating what eix does.

It's used only by q.

It's not the same as eix.  It's a bit similar to equery, except it's 
blindingly fast.  Compare for example the speed of:

   equery belong /bin/bash

vs:

   qfile /bin/bash

q is orders of magnitude faster.  I have both though, since some things 
can be done with the one but not with the other.

Got it.  Thank you!  :)
