2018-10-22Allow shell scripts to be embedded in the binaryRon Yorston6-1/+218
To assist in the deployment of shell scripts it may be convenient to embed them in the BusyBox binary. This patch adds two configuration options to the shell: - 'Embed scripts in the binary' takes any files in the directory 'embed', concatenates them with null separators, compresses them and embeds them in the binary. - 'Allow the contents of embedded scripts to be listed' makes the shell argument '-L name' list the contents of the named script. Both options are off by default. When scripts are embedded in the binary: - The shell argument '-L' lists the names of the scripts. - Scripts can be run as 'sh name arg...'. - An alias is added for each script, equivalent to "alias name='sh name'".

2018-09-30ifupdown: support "source-directory" stanzaBrandon Maier1-0/+16
Support the "source-directory" stanza from ifupdown[1]. source-directory will include all files in the named directory. Similar to the Busybox version of the "source" stanza, this version of source-directory does not currently support shell wildcards. We only check that the stanza starts with "source-dir" as ifupdown does[2].

Exuberant ctags creates an output file called "tags" by default or "TAGS" when it's run in emacs mode. Add those two files to .gitignore so they won't be removed by git clean -df. Signed-off-by: Martin Kaiser <martin@kaiser.cx> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
