Description Mike Gilbert gentoo-dev 2022-09-03 23:52:22 UTC
On a merged-usr system, both packages install /usr/bin/gzip and /usr/bin/gunzip.

Personally, I would just drop the "symlink" USE flag.

    profiles/base: mask app-arch/lbzip2[symlink], app-arch/pigz[symlink]
    
    Incompatible with merged-usr and is a fundamentally flaky approach.
    - app-arch/lbzip2: bug #868318 (possible solution in bug #868651)
    - app-arch/pigz: bug #868312 (possible solution in bug #868648)
    
    It's suggested that users who want this feature use a wrapper
    script in /usr/local (or otherwise on PATH), or configure tools
    like tar to use lbzip2 & pigz respectively using EXTRA_ECONF.

    app-arch/pigz: drop masked USE=symlink
    
    Use app-alternative/gzip instead (see news item).
