[Bug 1218852] Re: Hostnames with upper case letters don't make good MON's

[James Page]

** Description changed:

+ == Impact ==
+ The ceph upstart configurations don't work correctly on systems with hostnames that contain uppercase characters.
+ 
+ == Test ==
+ Easiest todo with juju:
+ Configured you environment name to have a uppercase letters in it.
+ juju bootstrap
+ mkdir raring
+ (cd raring; bzr branch lp:charms/ceph)
+ cat > local.yaml << EOF
+ ceph:
+   fsid: '6547bd3e-1397-11e2-82e5-53567c8d32dc'
+   monitor-count: 3
+   monitor-secret: 'AQCXrnZQwI7KGBAAiPofmKEXKxu5bUzoYLVkbQ=='
+   osd-devices: '/dev/vdb'
+   osd-reformat: 'yes'
+   ephemeral-unmount: '/mnt'
+ EOF
+ Deploy charm on raring using the above configuration
+ juju deploy --config local.yaml --repository . -n 3 local:raring/ceph
+ 
+ No ceph daemons will start due to missing uppercase pattern matching in
+ the upstart configurations.
+ 
+ == Regression Potential ==
+ Limited; this fix is already in Saucy (and tested OK) and simple extends the range of permitted chars to include uppercase letters
+ 
+ 
+ == Original Bug Report ==
+ 
  Its possible to configure a server with uppercase letters in the
  hostname: OS01-07  for example.
  
  When initializing a ceph mon filesystem this gets created OK in
  /var/lib/ceph/mon/ceph-OS01-07 - but the upstart configuration won't
  detect the mon filesystem as it contains uppercase letters.
  
  I was initially confused as running the same find command in the shell
  worked OK - but running it under the POSIX locale as happens in the
  upstart configuration causes the filesystem to be missed.
  
  I'm not 100% sure this is actually a bug - raising for discussion!

** Summary changed:

- Hostnames with upper case letters don't make good MON's
+ [SRU] hostnames with upper case letters don't make good MON's
