For the old fstab style, blanks and tabs are not allowed as delimiters

You need to add '\\' to the delimited list,

Can you try this patch for sendmail?

I'm exploring the 'local repository' tactics as described in:
http://www.scriptkiddie.org/freebsd/setting_up_local_repo.html
which makes use of the CVS_LOCAL_BRANCH_NUM evironment variable.
This is all under 4.7-RELEASE.
My general method is:
setenv CVS_LOCAL_BRANCH_NUM 1000

First I would like to know where I can buy a copy of the FreeBSD Developer's Handbook.
Nice to have a handbook that I can hold in my hand.
Secondly, What can I find a list of other interrupts within FreeBSD like the int 80h.
Or is this the only interrupt. Like example interrupt for video

Maybe, but they also support a lot of MMU-less architectures, so it may

No. The initial design of their VM greatly preceded NUMA and uCLinux. It
actually makes the system less portable

UVM was the VM system that replaced the old Mach style VM in NetBSD and (I
believe) OpenBSD. FreeBSD has already cleaned up a lot of the problems that
UVM addresses. However, there are still some things that could be done to
make map passing easier, which I believe would make zero-copy support

It's a toss up. Linux's use of registers for syscall args is not
a panacea, because many system calls require more then just the basic
call-used registers which means the linux userland code has to save
and restore those registers on the stack anyway. And we won't even
