Como Christopher sugeriu, archivemount
pode conseguir isso. Permite a gravação de arquivos e, quando desmontado, o arquivo .tar.gz é atualizado automaticamente para refletir as alterações.

Summary : FUSE based filesystem for mounting compressed archives
Description :
Archivemount is a piece of glue code between libarchive and FUSE. It can be
used to mount a (possibly compressed) archive (as in .tar.gz or .tar.bz2)
and use it like an ordinary filesystem.
