There is work being planned to replace the Bourne shell with a generic POSIX compliant shell. Whether that is an updated bash running in POSIX compatibility mode, or another shell such as ksh93 is still an open question. Either option require additional coding resources to implement. ===Q: Why isn't bash the default system shell?=== A: There is a consensus building to use a modern/user-friendly default system shell, such as bash or ksh93, but the integration and compatibility changes required have yet to be done.Sorry if this is nit-picky, but what does "default system shell" mean? If you mean the default for useradd (etc.), the word "system" is probably throwing me off. Maybe "default user shell" would be better? ~Iain
Isn't that what the first question addresses?
The actual shell could be the original bourne shell or another shell like either bash or ksh that is linked to /bin/sh and acts like a POSIX shell when the system executes it as /bin/sh. Some people could also be referring to the default shell that root uses.
Right. I think there could/should be a separate question for that too
(default shell for the root vs. default shell for newly-created users).
At least it seems that I'm not the only one for whom the above is
unclear...
