Did not realize that vi was already there...
But yes, my alias works:
EXOS-VM.37 #% cat test.cfgthis is my test
EXOS-VM.38 #% edit test.cfgthis is my test
~
...whereas vi directly does not:
EXOS-VM.38 #% vi test.cfgError: Invalid XOS Cli file extension with vi. Extension .pkt, .pol, .py, .xml, or .xsf is required.
