Comment (by eighthave):

 I imagine OpenWRT is one of the disk-constrained systems you are talking
 about, though these days perhaps it makes sense to also include Debian
 e.g. Raspberry Pi.

 * `zip:/path/to/my.zip/path/to/geoip` makes sense to me.  `.apk` and
 `.jar` files are both ZIP files with some extra standards, so it might
 make sense to include `jar:` and `apk:` as aliases for `zip:`.  Most
 people are not aware that `.apk` and `.jar` files are ZIP format.  iOS's
 [https://en.wikipedia.org/wiki/.ipa_(file_extension) .ipa] format is also
 a ZIP container, and it looks like iOS also reads PNGs straight from that
 file once installed.

 * [https://en.wikipedia.org/wiki/Deb_package .deb/.udeb] are `.ar` files
 with compressed `.tar` files (`.gz`, `bz2`, `.lzma`, `.xz`).  Supporting
 that case would probably require
 `deb:/path/to/tor_0.4.1.5-1.deb/path/to/geoip`.  libs for `.gz`, `.lzma`
 and `.xz` are already reguarly linked into `tor`. `.ar` and `.tar` support
 would need to be added.

 * OpenWRT's `.ipk` files seem to follow the same structure as `.deb`, but
 I couldn't find clear docs on that.  But
 [https://cognito.me.uk/computing/2014/05/06/manual-extractioninstallation-
 of-ipk-packages-on-gargoyleopenwrt.html it might use tar] instead of ar.

 * [https://en.wikipedia.org/wiki/RPM_Package_Manager#Binary_format .rpm]
 are compressed cpio files, the compression can be with gzip, zstd, lzma,
 xz, .bzip2.  RPM 5.0 allows xar instead of cpio.
