45 # Most of the calls to opt.samba_add_onoff_option() implicitly
46 # or explicitly use default=True
47 #
48 # To assist users and distributors to build Samba with the full feature
49 # set, the build system will abort if our dependent libraries and their
50 # header files are not found on the target system. This will mean for
51 # example, that xattr, acl and ldap headers must be installed for the
52 # default build to complete. The configure system will check for these
53 # headers, and the error message will indicate the option (such as
54 # --without-acl-support) that can be specified to skip this requirement.
55 #
56 # This will assist users and in particular distributors in building fully
57 # functional packages, while allowing those on systems truly without these
58 # facilities to continue to build Samba after careful consideration.
59 #
60 # It also ensures our container image generation in bootstrap/ is correct
61 # as otherwise a missing package there would just silently work
