It is the amount of VM that matters, with the private mmapings there
should be a lot less disk trashing when the RVM size exceeds the amount
of physical ram, as unmodified pages are not swapped out/in but simply
paged in from the RVM data file.

One problem we still have is that on linux it is not yet possible to
do a private mmap of a raw device, but hopefully that will be resolved
soon in the development kernels. Talk about implementing it has already

Ehh, config.tape, I don't thing we have one, ah yes... This is the one
on our backup server.

sleep_interval 200

notify   "/usr/sbin/zwrite -v -d -n -c backup -i coda "
#message   "echo "
message    "mail -s 'Backup notification'"

These are the configurable options and their defaults:

dbdir		"/vice/db"
labelsdb	"/vice/db/TAPELABELS"
sleep_interval	200
notify_cutoff	5
maxretries	25
backupmachine	undefined
message		undefined
notify		undefined

I know, haven't checked what the cause is yet. It is possible to
generate a tokenfile with `tokentool' and use that one from the
commandline with "-fromfile token", so it is either the parsing/reading
of the password, or the RPC message sent to the auth2 server.
