I am running system FreeBSD 7.1-STABLE amd64 GENERIC (Wed Feb 11
09:56:08 CET 2009) hosting few jails.
The machine has dual core CPU and some jails are set to run only on one
core (core 0 in this example):
host# cpuset -l 0 -j 25
As I tested today, root user inside the jail can change this by the same
command as I am doing it from the host system:
injail# cpuset -l 0,1 -j 25
And from now, jail with JID 25 is running on both cores.
Is it expected behavior of cpuset to allow user inside the jail change
cpuset of the jail itself or is it a bug?
It seems to me as undesirable.
