In an NFS environment, lack of synchronization between machine clocks
might create difficulties to any tool comparing dates and file time stamps,
like 'tar' in incremental dumps. This has been a recurrent problem with
GNU Make for the last few years. We would like a general solution.
** BSD compatibility matters.
Set LIBS to '-lbsd' before configuration (see 'INSTALL') if the linker
complains about 'bsd_ioctl' (Slackware). Also set CPPFLAGS to
'-I/usr/include/bsd' if <sgtty.h> is not found (Slackware).
** OPENStep 4.2 swap files
Tar cannot read the file /private/vm/swapfile.front (even as root).
This file is not a real file, but some kind of uncompressed view of
the real compressed swap file; there is no reason to back it up, so
the simplest workaround is to avoid tarring this file.
* Special topics
Here are a few special matters about GNU 'tar', not related to build
matters. See previous section for such.
** File attributes.
About *security*, it is probable that future releases of 'tar' will have
some behavior changed. There are many pending suggestions to choose from.
