#DESC Amanda - Automated backup program
|
|
#
|
|
# This policy file sets the rigths for amanda client started by inetd_t
|
|
# and amrecover
|
|
#
|
|
# X-Debian-Packages: amanda-common amanda-server
|
|
# Depends: inetd.te
|

|
#
|
|
# last change: 27. August 2002
|
|
#
|
|
# state : complete and tested
|
|
#
|
|
# Hints :
|
|
# - amanda.fc is the appendant file context file
|
|
# - If you use amrecover please extract the files and directories to the
|
|
# directory speficified in amanda.fc as type amanda_recover_dir_t.
|
|
# - The type amanda_user_exec_t is defined to label the files but not used.
|
|
# This configuration works only as an client and a amanda client does not need
|
|
# this programs.
|
|
#
|
|
# Enhancements/Corrections:
|
|
# - set tighter permissions to /bin/tar instead bin_t
