Three, actually. > Where do the rest of them come from? My half-finished regression test suite for busybox mount. I just rewrote the busybox "mount" command to fix a half-dozen bugs (the hardest of which was making it properly reentrant so "mount -a" behaves properly). And I basically had to derive a spec for mount from first principles (which I've halfway written up, should probably finish and post somewhere), and now I'm writing The Regression Test Of Doom. It runs under User Mode Linux, so it has a nice little clean root environment to work in and there's no worry about cleanup for when I typo something in the script and it crashes halfway through, because when the UML environment exits it takes its current mounts with it. Eventually I'll probably get it to run under a normal root environment... Let's see... Tarball attached, and I've been running it with: ~/linux-2.6.16-rc5/linux rootfstype=hostfs rw \ init=/home/landley/busybox/busybox/testsuite/mount.testroot \ TESTDIR=/home/landley/busybox/busybox/testsuite COMMAND=./mount quiet Rob -- Never bet against the cheap plastic solution.
