Perhaps this is more of a general linux question, but since ISPConfig introduced me to this, I'm asking here... When I'm working with the web directories, a few years back I discovered they have the "immutable" attribute set via "chattr +i/-i" and I have a couple questions about this attribute. 1) Is it only on the web folder? (I think so.) 2) How does the attribute relate to files inside the folder? 3) It appears when I rsync the directories (for backup purposes) rsync can access and retain all the proper attributes, but if I use the cp command or try to tar the directory without running "chattr -i" first, my archives get corrupted. I can successfully compress it into a .tgz file without errors during creation, but when I later try to unzip, the file is corrupt. At which point I go back, run "chattr -i", then it works. Why is that? Why doesn't the tar command throw errors right away? 4) If tar can't properly access the contained data, how is it that pureftpd accounts can successfully get in that directory and make changes? Thanks for the insights!
