[Bug 811476] [NEW] hangs while running etckeeper

[Rob Walker]

Public bug reported:

I have etckeeper installed to track changes to /etc using git.

After applying updates in kpackagekit, it hangs with the progress window
at 100% with the action "Committing changes"

Looking at the running processes, I see this:

 4786  1233 root     ?        Sl     0:06 /usr/lib/packagekit/packagekitd
 4920  4920 root     pts/2    Ss+    0:00  \_ /usr/lib/packagekit/packagekitd
29854  4920 root     pts/2    S+     0:00      \_ /usr/lib/packagekit/packagekitd
29855  4920 root     pts/2    S+     0:00          \_ sh -c if [ -x /usr/bin/etckeeper ]; then etckeeper post-install; fi
29856  4920 root     pts/2    S+     0:00              \_ /bin/sh /usr/bin/etckeeper post-install
29859  4920 root     pts/2    S+     0:00                  \_ /bin/sh /etc/etckeeper/post-install.d/50vcs-commit
29866  4920 root     pts/2    S+     0:00                      \_ /bin/sh /usr/bin/etckeeper commit --stdin
29887  4920 root     pts/2    S+     0:00                          \_ /bin/sh /etc/etckeeper/commit.d/50vcs-commit --stdin
29895  4920 root     pts/2    S+     0:00                              \_ git commit -F /tmp/etckeeper-git.tP2X3IaUpT

git log in /etc shows that the commit has been made sucessfully - the
most recent commit has the right date and the list of changes is what
has just been updated.

strace on the stalled git process shows:

[root at linchpin /etc <master>]# strace -p 29895
Process 29895 attached - interrupt to quit
write(1, "[master 82c5deb] committing chan"..., 490

Which suggests that nothing is reading from the stdout of the post
install hooks
