Funny, *every* time I mention this to anyone, they come up with this.  This is
definitely not what I meant. I meant everything under /usr provided by NetBSD's
base. /usr/pkg and /usr/src are separate partitions here simply because my / is
read-only. Also my root account definitely doesn't have /usr/pkg/* in its PATH.
And /usr/pkg is also mounted nosuid (and most of the time read-only). The major
reason for me to keep separate partitions in some cases is taking advantage
of read-only mounts to keep fsck time low after a crash. Additional reasons are
as mentioned keeping advantage of nosuid and noexec mount options. That's also
why /dev is not on my /, so that /dev and /dev/pts are the only partitions
mounted without nodev.

Please, tell me just one reason why /bin and /usr/bin shouldn't live on the
same partition.
