====== Compatibility with POSIX OSes ======

Until recently VCS has only been tested on Linux which, whith the GNU toolset, differs considerably from other UNIX-like OSes. These are some notes on the compatibility status.

The first and main target for compatibility is FreeBSD

====== POSIX ======

  * Worth a look: ''sedcheck'' (to check portability of ''sed'' syntax) http://lvogel.free.fr/sed.htm#sedcheck

====== FreeBSD ======

Experimental compatibility introduced in 1.0.100a.

Compatibility modifications (from the [[http://p.outlyer.net/vcs/files/CHANGELOG|Full changelog]]):
  * Call bash through env <=> bash is not always in ''/bin/bash''
  * Ensure we're using the correct getopt version
  * (1.0.100a) Try to use POSIX sed options when appropriate
    * (1.11) Use awk for complex regexes
  * Replaced incompatible sed constructs
  * Use mktemp's common GNU/BSD(/POSIX?) syntax
  * (1.0.100a) Use jot instead of seq if required and available
    * (1.11) Replaced by awk

''vcs'' works on FreeBSD 7.1-RELEASE but the output is still less refined than on Linux. See http://outlyer.net/2009-03-25:vcs-working-on-freebsd/.
\\ The output on FreeBSD 8.0 matches the one on Linux so it might be some (minor) problem with ImageMagick's arguments.

**Notes/References**

  * Mount ISOs: ''# mdconfig -a -t vnode -f file.iso''. Only root can set up loopbacks?
