When using "custom" installation with default packages,
vim-enhanced does not get installed. vim-enhanced is needed
by "crontab" command though, w/o vim-enhanced, crontab
will fail with "/usr/bin/vi - command not found" error.
Fix: install vim-enhanced or set EDITOR environment var
correctly: "export EDITOR=/bin/vi"
