A couple of weeks ago I suggested that ksh could be substituted for bash on a Linux server
Well I was wrong It turns out on RHEL, at least, that root uses /bin/sh BUT when you look in /bin you find /bin/sh is a soft link to /bin/bash [kbuntu has /bin/sh as a soft link to dash - so that is probably immune ] Now go a little further into the /etc/udev/rules.d and examine the scripts in there and low and behold there is BASH specific code which will fail for ksh : popd and pushd plus some other elements So if root tries to boot the system - normal - but is using ksh your system may fail to boot and could even corrupt the files in this directory and its game over - a re-install will be called for. I guess good ideas need to be tested ;-) cheers pwl
