You might see this as an inconsistency at the command->package
mapping level, but it's a consistency/compatibility at the
user/system level. Can you imagine having to go through and change
every script, program and user's memory every time a package name

Look at /etc/alternatives and the symbolic links in /bin and /sbin
for a range of remappings.

It has been a long time since one looked for a "csh" binary, even if
that's the shell in someone's passwd file entry that has been
brought forward from an older system. Then there's
sendmail->postfix. And, if you want a database, you still enter
"mysql", but now get mariadb.
