Mayne the 4K limit ist not the problem here. I did some "shortcutting"
and added one more "undefined" variable aaa.bbb.ccc:
# cat ./info.cf
bundle agent info
{
vars:
any::
"info_list" slist => {
"aaa.bbb.ccc ................ = $(aaa.bbb.ccc)",
"includes.dir ............... = $(includes.dir)",
"sys.arch ................... = $(sys.arch)",
"sys.bindir ................. = $(sys.bindir)",
"... BEGIN big shit ...............",
# "sys.inet6 .................. = $(sys.inet6)",
# "sys.interfaces_data ........ = $(sys.interfaces_data)",
"... END big shit ..............."
};
reports:
any::
"r1: $(info.info_list)";
"r2: sys.inet6 .................. = $(sys.inet6)";
"r3: sys.interfaces_data ........ = $(sys.interfaces_data)";
"r4: holleri di dudeldoe";
"r5: aaa.bbb.ccc ................ = $(aaa.bbb.ccc)";
}
Variables aaa.bbb.ccc and includes.dir are not defined and do not cause
any problems:
# cf-agent -IK --file ./info.cf --bundlesequence info
info: Using command line specified bundlesequence
R: r1: aaa.bbb.ccc ................ = $(aaa.bbb.ccc)
R: r1: includes.dir ............... = $(includes.dir)
R: r1: sys.arch ................... = x86_64
R: r1: sys.bindir ................. = /var/cfengine/bin
R: r1: ... BEGIN big shit ...............
R: r1: ... END big shit ...............
R: r4: holleri di dudeldoe
R: r5: aaa.bbb.ccc ................ = $(aaa.bbb.ccc)
Adding sys.inet6 leads to the problem:
# cat ./info.cf
bundle agent info
{
vars:
any::
"info_list" slist => {
"aaa.bbb.ccc ................ = $(aaa.bbb.ccc)",
"includes.dir ............... = $(includes.dir)",
"sys.arch ................... = $(sys.arch)",
"sys.bindir ................. = $(sys.bindir)",
"... BEGIN big shit ...............",
"sys.inet6 .................. = $(sys.inet6)",
# "sys.interfaces_data ........ = $(sys.interfaces_data)",
"... END big shit ..............."
};
reports:
any::
"r1: $(info.info_list)";
"r2: sys.inet6 .................. = $(sys.inet6)";
"r3: sys.interfaces_data ........ = $(sys.interfaces_data)";
"r4: holleri di dudeldoe";
"r5: aaa.bbb.ccc ................ = $(aaa.bbb.ccc)";
}
]# cf-agent -IK --file ./info.cf --bundlesequence info
info: Using command line specified bundlesequence
R: r1: $(info.info_list)
R: r4: holleri di dudeldoe
R: r5: aaa.bbb.ccc ................ = $(aaa.bbb.ccc)
Why is "r5:" shown but not "r2:" and "r3:"? Why isn't it possible to get
the reports "r2:" and "r3:"? There is something special with variables
sys.inet6 and sys.interfaces_data in my opinion.

Meikel
