Also this would probably be useful in the situation when you need
to change swap device on a running system. We had to do this once
or twice on a very busy commerical mail server running Solaris. We
needed to dismount current swap device and use it for other purpose
while having switched

Personally, I think it would be more intuitive to add a check to the allocation
algorithm that forces it to not consider devices flaged for removal, and
mark each page as free after it comes in. When the bitmap is clean you're done.
However, you're still going to want to count

One system I used to use years and years ago seperated this process into
stages. The swap(1M) command could be used to enable, disable and 'weight'
allocation to swap areas. The add was easy. 'delete' would cause the
device to be attempted to be

The weight idea is very interesting. NetBSD does this using
priorities; all the swap devices of a given priority are filled
round robin before devices of lower priority, the idea being that
the slower ones are a last resort (e.g. NFS). On the other hand,

Hi!
What is the status of the driver/file: /usr/src/sys/dev/my/if_my.c ..?
It will attach and work fine with tcpdump, netstat -i. But it won't allow me
to set an IP on the interface (ifconfig my0 inet 1.2.3.4 ..).
It's not present in LINT, but is present in /usr/src/sys/conf/files.
So, does anyone know how to use the basic unix tools to find
the offset of a string in a binary file ?
Specifically, I would like to locate the offset of the string
MFS Filesystem goes here
into a kernel compiled with with MD_ROOT option.
grep does not help because it gives the offset

Would grep -b do what you want?
