This is starting to annoy me. The crux of the problem is appears to be
a race condition between cabal and NFS:
$ cabal clean
cleaning...
Error while removing dist/: dist/setup: removeDirectory: unsatisified
constraints (Directory not empty)
$ ls -a dist/setup
. ..
Here are full transcripts, where /tmp is local and /home is NFSv3:
$ with-temp-dir sh -c 'darcs get --quiet http://darcs.net && cd * && cabal
clean'
with-temp-dir: entering directory `/tmp/with-temp-dir.ojCkNw'
[1 of 2] Compiling Distribution.ShellHarness (
Distribution/ShellHarness.hs, dist/setup/Distribution/ShellHarness.o )
[2 of 2] Compiling Main ( Setup.lhs, dist/setup/Main.o )
Linking ./dist/setup/setup ...
cleaning...
with-temp-dir: leaving directory `/tmp/with-temp-dir.ojCkNw'
$ TMPDIR=/home/twb/Desktop with-temp-dir sh -c 'darcs get --quiet
http://darcs.net && cd * && cabal clean'
with-temp-dir: entering directory `/home/twb/Desktop/with-temp-dir.nJpgKs'
[1 of 2] Compiling Distribution.ShellHarness (
Distribution/ShellHarness.hs, dist/setup/Distribution/ShellHarness.o )
[2 of 2] Compiling Main ( Setup.lhs, dist/setup/Main.o )
Linking ./dist/setup/setup ...
cleaning...
Error while removing dist/: dist/setup: removeDirectory: unsatisified

$
When I started writing this post I didn't realize it was only broken on
NFS. I guess I'll just forward it on to Duncan and the rest of the
Cabal team.
