        Gentoo's package management system is ideal to run a vserver. A vserver
"profile" could be created. A profile in gentoo's package management system
is a set of default package that must be installed or not-installed for a
specific architecture. With a vserver profile, we could have portage setup a
valid vserver automatically with no need of the newvserver command.

        A few additional ebuild would be necessary. I've included the vserver-sources
ebuild that installs and patch the source, it is for ctx16.

        Another ebuild is needed for the host system, for the vserver utilities. The
problem is that they do not work well with gentoo in their current state.
Main problem is the newvserver and vserver script that must be modified
slightly I think. Also, unification is rpm centric and I started
experimenting with the "epm" command in gentoo (sys-apps/epm) that tries to
emulate the rpm but works directly with gentoo's native packaging system.

        Having no access to a redhat system with "rpm" command, I don't know how
close "epm" comes to emulate the rpm output and interface.. Here's how it

# epm -qa

# epm -ql --dump freenet-
dir /var
dir /var/freenet
dir /var/freenet/stats
dir /usr
dir /usr/lib
dir /usr/lib/freenet
obj /usr/lib/freenet/freenet.jar a5fc4695d76156acdfc8b935d6c871f2 1046561669
obj /usr/lib/freenet/freenet-ext.jar 9ac68e0b202f0143869e2c44192e7261
dir /etc
obj /etc/freenet.conf c97270d05a0ba1d999e58ffdca708fa0 1046561669
dir /etc/init.d
obj /etc/init.d/freenet 24f25cc59216bf29f6312ecc48491c04 1046561669

        As you can see, there is no difference in the file lists between config files
and other files. Gentoo uses CONFIG_PROTECT and CONFIG_PROTECT_MASK for that,
in make.globals and that can be overrided in make.conf

CONFIG_PROTECT="/etc /var/qmail/control /usr/share/config
/usr/kde/2/share/config /usr/kde/3/share/config"
