[Vserver] this doc needs checking for accuracy
and possible additions proper editing will be done after the information within is accurate. - set up host as per gentoo how-to and create template as it specifies. add desired common services. start and test the template. create new-guest using skeleton method. cd into it and remove all entries then copy with cp -la gentoo/* new-guest to create hard links to the gentoo template. cd into new-guest and remove completely, etc, root, home and var i have setups for most internet services on the gentoo template and a regular user defined therefore home gets moved too. (should /usr/portage be moved and later recopied as 'real' files?) if i want to remove the ability to run certain services in this vserver, now is the time to remove the links to them so they are no longer a part of this guest. this is only necessary when allowing others shell access. most people would create a very minimal template server so this normally would not be necessary, but with my setups, i want all services available to every server even if i do not run them. then run setattr --iunlink * ONLY in the following directories inside new-guest bin sbin lib usr/bin usr/sbin usr/lib (should there be others?) setattr --~iunlink undoes any damage done to files that should not have that attribute. then cp -Rp /vservers/gentoo/etc and var and root and home this will give real files to edit and use in the new-guest config. configure new-guest as necessary start new-guest and enter to verify its operation. --- -- Chuck "...and the hordes of M$*ft users descended upon me in their anger, and asked 'Why do you not get the viruses or the BlueScreensOfDeath or insecure system troubles and slowness or pay through the nose for an OS as *we* do?!!', and I answered...'I use Linux'.
