| Is it necessary to do an emerge -u system after the emerge sync to update the portage tree? |

| It's my understanding that "emerge sync" updates the Portage tree on your system while "emerge -u system" will update all critical system packages to the latest version number. |

'emerge sync' just grabs all of the new metainformation (ebuilds) about
software packages - i.e., what the latest versions are, what's stable/unstable, where to download,
how to build/install, etc. 'emerge -u' actually upgrades the named package(s) if a newer
version is available. Plus, there's 'emerge -u system' and 'emerge -u world', which
upgrade the core components of your system
and everything else, respectively.
For example:
will try to update mplayer to its latest release, if there is a newer one available.
will try to update all of the core components of your system (gcc, glibc, binutils,
system layout stuff, etc.) should any newer versions be available.
will try to update the rest of the software on your system, should newer versions
be available.
That's a really basic overview. Much more info is available in the man page for emerge; especially, look for the
-D option and exactly what 'system' and 'world' mean for some extra info.
What it all boils down to is the following "standard procedure" for updating everything (e.g., I do some variation of it
once a month):
| Code: | emerge sync
emerge -u system
emerge -u world

just go ahead and compile your system to your liking.. then get it running.. then do all the updates and extra configuring   |

I as well as most people recommend doing an emerge -u or -U (depending on unstable packages) world over emerge -u system.
