Opinions on db operating systems Wanted

I am interested in hearing anyones opinions on what OS they would choose to run a MySQl db and the reasons why, of course. I have a task to build a db server for a project that will be very busy if things work as the creative minds think that it will. I am running a FreeBSD box right now on Athlon MP, but this box will be taken as soon as it is replaced by this machine right now. This machine works fine under current load, but I am not making the decisions. I am just interested in figuring out the best choice now, instead of finding that I could have made a better choice down the road when we are getting pouded with queries.

We are thinking about dual Opteron procs. Is there a better OS to run a 64 bit Mysql Innodb db in anyones experience?

Thanks,
Bob

settaskid(2) System Calls settaskid(2) NAME
settaskid, gettaskid, getprojid - set or get task or project IDs SYNOPSIS
#include <sys/types.h> #include <sys/task.h> #include <unistd.h> taskid_t settaskid(projid_t project, int flags); taskid_t gettaskid(void); #include <sys/types.h> #include <sys/task.h> #include <unistd.h> #include <project.h> projid_t getprojid(void); DESCRIPTION
The settaskid() function makes a request of the system to assign a new task ID to the calling process, changing the associated project ID to that specified. The calling process must have sufficient privileges to perform this operation. The flags argument should be either TASK_NORMAL for a regular task, or TASK_FINAL, which disallows subsequent settaskid() calls by the created task. The gettaskid() function returns the task ID of the calling process. The getprojid() function returns the project ID of the calling process. RETURN VALUES
Upon successful completion, these functions return the appropriate task or project ID. Otherwise, -1 is returned and errno is set to indi- cate the error. ERRORS
The settaskid() function will fail if: EACCES The invoking task was created with the TASK_FINAL flag. EAGAIN A resource control limiting the number of tasks or LWPs in the current project or zone has been exceeded. EINVAL The given project ID is not within the valid project ID range. EPERM The {PRIV_PROC_TASKID} privilege is not asserted in the effective set of the calling process. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |MT-Level |Async-Signal-Safe | +-----------------------------+-----------------------------+ SEE ALSO
