+ * Fixed a _horrible_ bug where 'tar -tvf' could unlink
+ local files!!! Fix thanks to Marius Groeger <mgroeger@sysgo.de>
+ * Fixed a nasty bug in tar when could mess up saved symlinks.
* Updates to handle Linux 2.4.0 kernels (kludged around the
"none" entries in /proc/mounts, added a hack to make sysinfo
work with both old and new kernels).
- * Fixed a nasty bug in tar when could mess up saved symlinks.
* Fixed insmod module option parsing for options lacking an '='.
Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
* Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
Fix thanks to Arne Bernin <arne@matrix.loopback.org>
+ * Added support for "sh -c command args...", thanks to
+ Marius Groeger <mgroeger@sysgo.de>
