[gentoo-user] More on /sys files

[gentoo-user] More on /sys files

[Harry Putnam]

I'm in the process of rsyncing an OS to a remote file system.

when rsyncing /sys to remote /sys... I get piles of errors of the
form:
  WARNING: devices/LNXSYSTM:00/device:00/ACPI_CPU:00/power/wakeup failed
  verification -- update discarded (will try again).

This is after a session failed so I'm re rsyncing directory by directory
to make sure all is copied over.

du -sh /sys on both remote and local shows:
  0


But find shows something else:
 find /sys -type f|wc   (on remote host)
  5850

find  /sys -type f|wc -l (on local host)
   6915

What do I need to do to get remote /sys  to mirror local /sys
Will booting the remote... once the transfer is done cure the problem?

Why do you need to sync /sys? It's completely useless - kernel creates all
files in /sys automatically.

/sys is a virtual filesystem, like /dev and /proc. Even if you do succeed
on copying the contents,you'll only waste space on the root partition of
the new machine and the virtual filesystems will get mounted over
them. On my desktop, one file in /proc is more that ten times the size of
the root filesystem!

Use the -x option with rsync to prevent copying these.
