Do you really need a DB though ? > Having a DB that has the history of every file on the system: what > package, date, package version, filename, directory, would be useful. Could it not be a simple flat file listing ? find / -newer SOME_TIMESTAMP_FILE -ls where SOME_TIMESTAMP_FILE is touched after every package install would seem to do all that one wants. > It's also well beyond what I think should be in LFS.

One thing I found appealing about the Package-User hint and it's methodology, was that such clashes were explicitly flagged whenever a newer package tried to overwrite and existing file. It was then up the installer to decide what to do. It's not clear that use of DESTDIR, on it's own, would make that issue any easier to sort out. What one would appear to need to do is to go down the PkgSrc route where one creates a list of files after the DESTDIR install which can then be altered so as not to overwrite existing files in the install proper by virtue of inspecting the DESTDIR installtion against the file in the live system and removing those which should not be overwritten by that package's version. But then one is installing against an existing list of files which seems to complicate matters in that you either have to trust someone who created the list ahead of your install or jump through a couple more hoops when installing yourself. Then again, maybe that "trust" is no more than that afforded to the writers of the install commands in the *LFS books? -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
