Why the exception for busctl and systemctl?
You aren't actually solving any problems with redefinition in this
patch. You're actually making the problem worse. Instead of redefining
*some* common functions on completion load, you're forcing *all* common
functions in systemd-helpers to be redefined (even if only 1 is used). I
don't really see this as a problem, though, and you don't explain why
you seem to think it is.
How is sourcing this library supposed to work? Each file contains:
But that file won't be in $PWD when completions are loaded. Sourcing
works like any other command -- relative paths will be relative to the
current process's $PWD, not relative to the disk file calling source.
Without cd'ing into /usr/share/bash-completions/completions, this
doesn't work (and please don't cd from completions).
I'm not against deduplicating this common code, but you'd be better off
using m4_include to preprocess the completions at build time.
