Hello Peasant,

Sorry for the delay, I've been in court for two weeks Smilie . Don't worry, it was only jury service Smilie

Yes! This works wonderfully. I've trimmed it down so finding that the necessary part was just --xattrs-include='security.capability' so I can now prove it with:-
Code:
# tar -cvpzf - --xattrs-include='security.capability' /usr/bin/ping | ( cd /tmp && tar -xzvp --xattrs-include='security.capability' -f - )
tar: Removing leading `/' from member names
/usr/bin/ping
usr/bin/ping

# getcap /tmp/usr/bin/ping
/tmp/usr/bin/ping = cap_net_admin,cap_net_raw+p

This command now works perfectly and I can incorporate it into our kickstart called recovery process with a minor adjustment to the procedure to build the image.

Fantastic.

One wonders why they create so many additional attributes for files and then the default doesn't recover them. I presume it is so that it you try to extract to a server that tar is not expecting them, you don't get horrible errors, but it is frustrating. Oh well Smilie


Thank you very much once again,
Robin

NAME
shells - shell database SYNOPSIS
/etc/shells DESCRIPTION
The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser- shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root. A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by the routines which search the file. Blank lines are also ignored. The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh, /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list. Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1). FILES
