some errors

/sys  ( also /proc , probably others )
some things that looks like directories and files, do not make sense to copy
to another computer.
generally, these give some kind of access to running kernel-type things.
I think some of these "files" are write-only  or would give information
about some hardware (if you had the hardware)

also some things like /dev/zero or /dev/null   (anything in /dev, probably)
needs special handling.

/mnt/  tends to catch anything mounted  (like CDs and stuff)

# mount
/dev/sda3 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sda1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

  Just wondering what could cause the following errors:

  rsync: read errors mapping "/sys/block/loop4/dev": No data available (61)

  rsync: send_files failed to open
"/sys/bus/pci/drivers/Promise_Old_IDE/new_id": Permission denied (13)

  ERROR: sys/block/ram2/stat failed verification -- update retained.
  rsync: read errors mapping "/sys/block/ram2/stat": No data available (61)

  Thank you in advance!
