Portable-AppImage-TAR maintenance
Each distro provides a mechanism for adding applications to its foundational base system. It is maintained, adequately, in its Package Management (PM) subsystem. There are, though, several other 'accepted' options for adding applications to a system.
Request: Your ideas for maintaining Portables, AppImages, TARs, SFSs, Flatpaks, etc.
Scenario
I have a portable that I want to add to the system's behavior; say one of the browser portables. 2 things:
I would like to have a folder reference point for these kinds of additions.
And, I would like to know where to link the utility within the distro's filesystem.
Same would be done for all such additions to the system outside of the distro's PM such that they can be callable at any time.
According to your understanding of the Linux Architecture and some common base of Linux's filesystem; where in the filesystem linkage would you recommend these be linked such that it is clear that they are 'subsystem-application additions' beyond distro's PM?
Looking for ideas. Want to consider methods for Good Housekeeping of additions beyond the scope of the PM.
P.S. Free free to recommend external folders that would be containers for the links in the running directory architecture, as well. Please understand that this question set has nothing to do with compression/encryption of external folders; merely allocation benefit for referential housekeeping.
Hope this request for your ideas or recommendations does not confuse.
