Doesn't clearcase play games with libc to create filesystem views
organized to match the repository? (I always found that kind of spooky:
a revision control system which is also a rootkit...)

I have no idea about linux-emulation but there's a short howto on the
wiki (it's for 1.4 but there might be some clue):

Thanks Erik,

Saw that. Did that. I thought there was something in the emulation layer
that intercepted .. oh, there it is in emulation/linux/linux_util.c.

Hasn't changed in a long time .. question is, why doesn't it work now ? ..

Hmm, I've got some room in my root partition .. maybe try losing the
symlink and see if that helps -

1. ls -ld /compat
   lrwxr-xr-x 1 root wheel 13 Apr 18 15:03 /compat -> /usr/pkg/emul

Nah, it's got a loadable kernel module that plugs into the vfs and looks
like a filesystem to the upper layers. Same idea as nullfs. But on the
lower end it does rpc's to a remote database 'version object base' aka
'vob' server, and has a cheap and cheerful local database cache aka a
'view' - also talked to through rpc over loopback I think. That's really
a thumbnail sketch and I'm probably mis-remembering a bunch of things.

Without the kernel module, it still does useful stuff, you can still use
something they call a snapshot view. In a snapshot view, the vob server
database gets blatted out onto a local filesystem and that effectively
becomes your cache - equivalent to cvs checkout'ing a code tree, and
works similarly.

Of course, on the kernel module side they support Linux, Sun(Sparc),
HP, AIX, and UW2 aka Novell Unix, or whatever it's called these days.

I've been told by grog and a few others that shimming the Linux kernel
module is pretty much a no-go because the Linux vfs api is quite different
from all others.

There might be a chance with the Uw2 module, but it's been quite a while
since I thought about trying it. ;)

Andrew.

is this still a bug?
