+ - get rid of global state variable CurrentHost. This will enable upcoming
+ changes.
+ - UDLdap.py: make a cache for __getitem__() decisions.
+ - wrap cdbmake calls in eatmydata. Nothing else does any fsync stuff,
+ so doing it here just costs a lot.
+ * ud-generate: Use a flock() lock instead of python's lockfile class.
+ * ud-generate: The ssh authorized_keys file for the sshdist user now wraps
+ the rsync call in an flock wrapper that acquires a shared lock on
+ ud-generate's lock. This prevents syncing while ud-generate runs.
+ * ud-lock: support supplying a status to set instead of 'retiring'.
+ * ud-generate: Also rebuild if one of our keyrings has changed, even if
+ ldap has not.
+ * userdir-ldap-slapd.conf.in: explicitly list readable attributes.
+ End with 'by * none'.
