Hi,
as the length of interfaces aliases is limited and the aliases are
determined by the vservername long vservernames break the suffix concept
of the (util-)vserver tools as the alias is simply truncated and the
suffix is dropped. That means, that vservers with longnames will only
have the last assigned address available, as the others are
consecutively overwritten. The attached patch causes the alias name to
be the vservername truncated to 8 chars to avoid this problem. The
downside is that vservernames have to differ within the first 8 chars
this way instead of `whatever this was before` (guess it was about 10
chars).
