How to identify what files have changed after installing new software?

[as]

I want to create an overlay initramfs containing the files required for a new application.

So first step is to create a clean tinycore install
Second step is to install the software and make sure it is configured properly
Third step is to identify exactly what files have changed to I can copy them onto an initramfs.

What's the most effective way to carry out step 3 - i.e. to identify exactly which files changed when I installed my application?

thanks!

Hi as
Have you looked at the extension creation section of the Wiki? Check the  "When DESTDIR Fails"  paragraph.

NOTE: If you automate the build (in a script) be sure to add sleep 1 otherwise you may find you're missing files if the BUILD is quick

• Create your time-stamp file
• Sleep 1 (ensures ALL of your new files are OLDER than the time stamp)
• BUILD your project
• sync (helps ensure files are actually WRITTEN, thus found)
• Sleep 1 (for safety, probably not needed)
• Run Find (and filter unneeded directories/files!)

Hi centralware
The second  sleep  is not needed,  sync  does not return until all file have been written.

Timestamping may not find all newly installed files. There may be files (e.g. config, doc, etc.) just copied with their original date. Add them manually to your build script.

hi friends,

perhaps the filetool inotify ccould help you to monitor changes of files and dirs:
f.e. inotifywait -r -e create -m $HOME

keep on hacking :-)

I figured as much, but tend to take the safe route
I remember back in the day where a machine was "too fast" running a task (time-stamped) so I've been scripting the before and after as a precaution for over a decade now.
