Angels and pin-heads ...
Y'all both missed the point. Although Greg's dissertation on
uuids was interesting, the salient fact is that you run out of
machine way before you run out of uuid, in most practical cases.
Who uses NIS these days? It's taboo around here and NFS is only
allowed for Unix server-to-server file shares, even those get
reviewed, on a must-need basis. The point of my message was to
answer the question, not to debate relative kernel
merits/methods. Who cares how many uuids a given kernel can
support as long is the number is larger than the silicon can
support? So what is my original numbers were a little dated, they
were still irrelevent in determining the number of users a system
can support. My point was that the planned load is the sole
determinant. The original poster was asking a system capacity
question, not a religious question.
<sheesh> You'd think I was in DOMAIN-POLICY.
