Clone Arch root

This script will make a clone of my root directory onto a mounted partition. It is far from perfect!
It requires my root /etc/fstab plus a "clone-version" /etc/fstabClone (see below)
It requires folders /mnt/ssdRootClone on the original and /mnt/ssdRoot on the Clone.
I run it as root.

    # rsync options used
    #
    # -a, --archive
    # This is equivalent to -rlptgoD. It is a quick way of saying  you
    # want  recursion  and want to preserve almost everything (with -H
    # being a notable omission).  The  only  exception  to  the  above
    # equivalence  is when --files-from is specified, in which case -r
    # is not implied.
    #
    # Note that -a does not preserve hardlinks, because finding multiply
    # linked  files is expensive.  You must separately specify -H.
    #
    # -u, --update
    # This  forces rsync to skip any files which exist on the destination 
    # and have a modified time that  is  newer  than  the  source file.
    # (If an existing destination file has a modification time equal to
    # the source file's, it will be updated if the sizes  are different.)
    #
    # Note  that this does not affect the copying of symlinks or other
    # special files.  Also, a difference of file  format  between  the
    # sender  and receiver is always considered to be important enough
    # for an update, no matter what date is on the objects.  In  other
    # words, if the source has a directory where the destination has a
    # file, the transfer would occur regardless of the timestamps.
    #
    # This option is a transfer rule, not an exclude,  so  it  doesn't
    # affect  the  data  that  goes  into  the file-lists, and thus it
    # doesn't affect deletions.  It just limits  the  files  that  the
    # receiver requests to be transferred.
    #
    # -H, --hard-links
    # This tells rsync to look for hard-linked files in the source and
    # link together the corresponding files on the destination.  With-
    # out  this option, hard-linked files in the source are treated as
    # though they were separate files.
    #
    # This option does NOT necessarily ensure that the pattern of hard
    # links  on  the  destination  exactly matches that on the source.
    # Cases in which the destination may end up with extra hard  links
    # include the following:
    #
    #
    # o      If  the  destination contains extraneous hard-links (more
    #        linking than what is present in the  source  file  list),
    #        the  copying  algorithm  will  not break them explicitly.
    #        However, if one or more of the paths have content differ-
    #        ences,  the  normal  file-update process will break those
    #        extra links (unless you are using the --inplace  option).
    #
    # o      If you specify a --link-dest directory that contains hard
    #        links, the linking of the destination files  against  the
    #        --link-dest files can cause some paths in the destination
    #        to become linked together due to the --link-dest associa-
    #        tions.
    #
    #
    # Note  that  rsync  can only detect hard links between files that
    # are inside the transfer set.  If rsync updates a file  that  has
    # extra  hard-link connections to files outside the transfer, that
    # linkage will be broken.  If you are tempted to use the --inplace
    # option to avoid this breakage, be very careful that you know how
    # your files are being updated so that you  are  certain  that  no
    # unintended  changes  happen due to lingering hard links (and see
    # the --inplace option for more caveats).
    #
    # If incremental recursion is active (see --recursive), rsync  may
    # transfer a missing hard-linked file before it finds that another
    # link for that contents exists elsewhere in the hierarchy.   This
    # does  not  affect the accuracy of the transfer (i.e. which files
    # are hard-linked together), just its efficiency (i.e. copying the
    # data for a new, early copy of a hard-linked file that could have
    # been found later in  the  transfer  in  another  member  of  the
    # hard-linked  set  of files).  One way to avoid this inefficiency
    # is to disable incremental recursion using the --no-inc-recursive
    # option.

Post about getting MythTV backend to wake for recordings

Thanks, Lester_Burnham for this post!

Simple test to wake the machine 5 minutes from now (if this works, you're pretty much set)

sudo sh -c "echo 0 > /sys/class/rtc/rtc0/wakealarm"
sudo sh -c "echo `date '+%s' -d '+ 5 minutes'` > /sys/class/rtc/rtc0/wakealarm"
cat /sys/class/rtc/rtc0/wakealarm

Check

cat /proc/driver/rtc

This should return a list of parameters. Check the alrm_time is 5 minutes into the future and the alrm_date is today. Shutdown your computer and see if it comes back up in ~5 min.

sudo shutdown -h now

If the alarm is set then you should see something like this. If so then shutdown and see if it wakes up at the alarm date/time.

rtc_time : 13:40:26
rtc_date : 2008-12-21
alrm_time : 10:45:00
alrm_date : 2008-12-22
alarm_IRQ : yes
alrm_pending : no
24hr  : yes
periodic_IRQ : no
update_IRQ : no
HPET_emulated : no
DST_enable : no
periodic_freq : 1024
batt_status : okay
