Right, bash is 4 times the size of dash. That adds up when you're forking the shell a hundred times or whatever during boot. The last time I tested, it shaved like 4 seconds off boot using dash instead of bash. http://linuxfromscratch.org/pipermail/lfs-support/2008-February/034192.html I use bash all the time and I wouldn't consider using a minimal posix shell for my login shell. For any non-trivial script, I use bash. However, for a generic shell script, I don't know why you couldn't make it posix compliant. That allows people to have flexibility without much loss. The bootscripts are pretty simple. Of course, you can keep bash as /bin/sh if you like. Or make it zsh or ksh or dash or posh... -- Dan -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
