Hi automake folks, What do you think about changing Automake's default tar format from v7 to ustar?
Are you aware of any system 'tar' that does doesn't cope with ustar? What do you think about defaulting to the --format=posix PAX format? It may be just as safe as ustar, and only if a package uses some feature (like >255 long filenames) that require PAX then it would be enabled, otherwise it will remain ustar-compatible. Discussion on the gnulib list suggests that at least ustar ought to be safe to use these days. /Simon Bruno Haible via Gnulib discussion list <bug-gnu...@gnu.org> writes: > Simon Josefsson wrote: >> Possibly automake can move >> from v7 to ustar.
