Title: Webmin 1.52 Extension (making one ?)
Post by: Terminator3000 on October 06, 2010, 10:52:16 AM: Hi as a follow up to my post on Busybox here http://forum.tinycorelinux.net/index.php?topic=7405.0 Ive got a related query.
I installed Webmin 1.52,a server admin interface, which went fine except that I forgot to include all the new files and folders in /opt/.filetool.lst and they promptly disappeared on reboot!
So,I'm doing them again but am wondering if I could create a tcz extension of this whereby the problem wouldn't arise.

Webmin is available in tar.gz format but this contains a sh setup script which performs all the necessary actions.

I currently have little experience of C coding/compiling being only a student of Java and PHP so any tips on how to do this are welcome Thanks.

I'd suggest you ensure to use the '/usr/local' area of the filesystem (e.g. that any executables or scripts end up in '/usr/local/bin'). Having a shell script for installation indicates to me that no compilation was involved, so that should lessen your need to know C.

In the end you'll have to figure out what this install script does, i.e. which additional files it stores in which directory. Probably along the lines of what section 4 of the Wiki (http://wiki.tinycorelinux.com/Creating+Extensions#When_DESTDIR_Fails) suggests: the file names would have to be put into a list (similar to what the 'find' command achieves in the Wiki), and then a temporary tar-archive would have to be created that contains the files in their hopefully "TC-compatible" setup. This tar-archive finally needs to be converted into an SquashFS file which is your target extension. I personally would prefer to skip over the tar-archive step, and go straight into setting up the target directory structure, but that depends on how well one knows certain commands.

Please make a really serious effort in reading the Wiki and working out what the suggested commands are doing (e.g. checking out man-pages, as can be found on http://linux.die.net ). I for one are not planning to serve you every single command on a "silver platter".
