While extracting a tarball, GNU/tar told me:
Ignoring unknown extended header keyword `SCHILY.dev' Ignoring unknown extended header keyword `SCHILY.ino' Ignoring unknown extended header keyword `SCHILY.nlink'Hm, what does that remind me of? Ah, star! Digging in the bits still left on BerliOS, there seems to be something what looks like a POSIX proposal:
$ cat star/README.posix-2001 [...] Star supports the following fields in the extended header: [...] Vendor unique: "SCHILY.devmajor" "SCHILY.devminor" (create/extract) In -dump mode (a preparation for incremental dumps) star archives: "SCHILY.dev" The field stat.st_dev - the filesys indicator "SCHILY.ino" The field stat.st_ino - the file ID # "SCHILY.nlink" The field stat.st_nlink - the hard link count "SCHILY.filetype" The real file type - this allows e.g. socket/doorWow. Alas, these headers remain unrecognized in GNU/
tar, hence the (benign) warnings.
