I'm updating the FreeBSD port to got 0.50, and regress/cmdline/update.sh
throws an error:

./update.sh -q -r "/tmp"

test failed; leaving test data in /tmp/got-test-update_conflict_wt_rm_vs_repo_rm-jQlcrkFR

Specificially, it's the line

  (cd $testroot/wt && got update > $testroot/stdout)

in test_update_conflict_wt_rm_vs_repo_rm().

I've bisected this down to commit e600f1246e15, "ensure that old
commits remain referenced after rebase and histedit".  Unfortunately
that is a large change.

The ktrace is baffling.  On FreeBSD I see

 47982 got      CALL  openat(AT_FDCWD,0x800704080,0x100<O_RDONLY|O_NOFOLLOW>)
 47982 got      NAMI  "/tmp/got-test-update_conflict_wt_rm_vs_repo_rm-ZzWKzRq6/wt/beta"
 47982 got      RET   openat -1 errno 2 No such file or directory
 47982 got      CALL  readlink(0x800704080,0x7fffffffd430,0x400)
 47982 got      NAMI  "/tmp/got-test-update_conflict_wt_rm_vs_repo_rm-ZzWKzRq6/wt/beta"
 47982 got      RET   readlink -1 errno 2 No such file or directory

Meanwhile, on OpenBSD there's

 61448 got      CALL  open(0x1d3545fec00,0x100<O_RDONLY|O_NOFOLLOW>)
 61448 got      NAMI  "/tmp/got-test-update_conflict_wt_rm_vs_repo_rm-ybHVRPHj\
        /wt/beta"
 61448 got      RET   open -1 errno 2 No such file or directory

and then it proceeds to do other things.  There is no readlink()
call.
