• No changes made in the configuration files will take effect until the `update-grub` command is also run.

GRUB_TIMEOUT=5 - No change from Grug Legacy. This is the number of seconds before the default entry is automatically booted.
• 0 The menu will not be displayed. There will be no delay. When this entry is set to 0:
  • The user may force displaying the menu as the computer boots by holding down the SHIFT key.

GRUB_HIDDEN_TIMEOUT=0
• The menu will be hidden unless a # symbol is present at the beginning of this line. ( # GRUB_HIDDEN_TIMEOUT=0 )

GRUB_HIDDEN_TIMEOUT_QUIET=true
• true - No countdown is displayed. The screen will be blank.
• false - A counter will display on a blank screen for the duration of the GRUB_HIDDEN_TIMEOUT value.

The "%i" escape has a cryptic output that is 11 letters long. The general
format is like the string YXcstpoguax, where Y is replaced by the
type of update being done, X is replaced by the file-type, and the
other letters represent attributes that may be output if they are being
modified.



The update types that replace the Y are as follows:





• A < means that a file is being transferred to the remote host
  (sent).
  
• A > means that a file is being transferred to the local host
  (received).
  
• A c means that a local change/creation is occurring for the item
  (such as the creation of a directory or the changing of a symlink, etc.).
  
• A h means that the item is a hard link to another item (requires
  --hard-links).
  
• A . means that the item is not being updated (though it might
  have attributes that are being modified).
  
• A * means that the rest of the itemized-output area contains
  a message (e.g. "deleting").
  
• A c means either that a regular file has a different checksum
  (requires --checksum) or that a symlink, device, or special file has
  a changed value.
  Note that if you are sending files to an rsync prior to 3.0.1, this
  change flag will be present only for checksum-differing regular files.
  
• A s means the size of a regular file is different and will be updated
  by the file transfer.
  
• A t means the modification time is different and is being updated
  to the sender's value (requires --times). An alternate value of T
  means that the modification time will be set to the transfer time, which happens
  when a file/symlink/device is updated without --times and when a
  symlink is changed and the receiver can't set its time.
  (Note: when using an rsync 3.0.0 client, you might see the s flag combined
  with t instead of the proper T flag for this time-setting failure.)
  
• A p means the permissions are different and are being updated to
  the sender's value (requires --perms).
  
• An o means the owner is different and is being updated to the
  sender's value (requires --owner and super-user privileges).
  
• A g means the group is different and is being updated to the
  sender's value (requires --group and the authority to set the group).
  
• The u slot is reserved for future use.
  
• The a means that the ACL information changed.
  
• The x means that the extended attribute information changed.

Integrate into mythTV

Block shutdown: (checked, if you run frontend and backend on 1 machine. Do not check if you do not automatically start the front end, and want the system to shut down after an automatic recording.)

Idle shutdown timeout (secs): 1200 (if you set this to 0, it will disable auto shutdown)

Max. wait for recording (min): 120

Startup before rec. (secs): 600 (If you have not disabled the occasional disk check on boot, make this time long enough to complete the boot & disk check before the recording should start)

Wakeup time format: time_t

Command to set Wakeup Time: sudo sh -c "/usr/bin/setwakeup.sh $time"

Server halt command: sudo shutdown -h now

Pre Shutdown check-command: (leave this blank)

Add the following line to your /etc/sudoers by running "sudo visudo" and pasting the line at the end of the file.

%mythtv ALL = NOPASSWD: /sbin/shutdown, /bin/sh, /usr/bin/setwakeup.sh
