187 Directories (keys) under `userdata` are limited to 53 character length, and
188 data in `userdata/<key>/value` are limited to 200 bytes::
192  mkdir userdata/foo
193  echo bar > userdata/foo/value
194  mkdir userdata/qux
195  echo baz > userdata/qux/value
207 Preview the userdata that will be appended with::
209  cd /sys/kernel/config/netconsole/cmdline0/userdata
210  for f in `ls userdata`; do echo $f=$(cat userdata/$f/value); done
212 If a `userdata` entry is created but no data is written to the `value` file,
217  mkdir userdata/foo
218  echo bar > userdata/foo/value
219  mkdir userdata/qux
227 Delete `userdata` entries with `rmdir`::
229  rmdir /sys/kernel/config/netconsole/cmdline0/userdata/qux
235      mkdir userdata/testing
236      printf "val1\nval2" > userdata/testing/value
237      # userdata store value is called twice, first with "val1\n" then "val2"
