That would probably work for symlinks, since they cannot be updated.
But this would requires heavy chan

I did that and the SMART status is OK.
So, anything short of re-booting the server to unlock the locked up SATA port?
I'll be losing 455 days of uptime!

I'd see if it reacts to
I am about adding linkat(2), which is defined in
The Open Group Technical Standard, 2006, Extended API Set Part 2.
However, I am not going to implement the whole Extended API Set Part 2,
at least for now. This means I am going ot have linkat(2) but not
openat(2) for instance.
That approach brea
hello. On a NetBSD-4.x system, I know of no way to re-enable the SATA
port short of rebooting. Once rebooted, of course, you'll be able to
rebuild your raid and start counting those uptime days again.

Gentlepeople,
Some file systems use genfs_compat_getpages while others (most of them) use
genfs_getpages. I'm trying to figure out the essential differences, and why
one would pick one over the other.
Any pointers?

I can answer to myself: through config.h -> float.h -> whatever,
_NETBSD_SOURCE gets defined in

modload looks for modules first in the current working directory, if not
found there the system module area is searched (/stand/...).
otoh, we don't look in '.' when we load libraries in userspace programs,
we even removed '.' from the Lua loader but when it comes to kernel code
we happily accept
i like the current method. it is how pretty much all other
systems i'm familiar with work, too.
