There is a way to achive this:
1) create a directory /usr/xxx/bin/ that is allowed to include ambiguous
names for "xxx"-tools. GNU tar could be called "tar" in this dir.
2) create a directory /usr/xxx/ubin/ that is only allowed to include
unique named for utilities. Make sure that all commands either from
/usr/xxx/bin/ or from /usr/xxx/ubin/ only call tools from /usr/xxx/ubin/
in order to avopid name clashes (see point #3 below).
GNU tar needs to be called "gtar" in this dir.
3) make sure that /usr/bin/ does not contain ambiguous names such as
"compare" with is a name clash recently introduced by ImageMagick
and that is in conflict with a utility of the same name that I
publish 15 years longer than ImageMagick exists.
4) Utilities that are from a smaller consolidation or do not get an own
"xxx" _need_ to be forced to convert to use unique names. This seems
affect the name clash introduced by ImageMagick.
This allows people to do anything they may like using the folloing method:
People unter these rules could have any /usr/xxx/ubin/ type directory in their
PATH.
People could have a set of /usr/xxx/bin/ directories in their PATH in an order
that is related to their favors.
Only if someone likes to by default use e.g. "GNU cut" as his default "cut" and
"Schily paste" as his defaule "paste", he would need to create a directory:
$HOME/bin with symlinks
cut -> /usr/gnu/cut
paste -> /usr/schily/bin/paste
