[bug#77680] [PATCH 0/4] Avoid 'fdatasync' calls for cache files

[Ludovic Courtès]

Hello,

As Chris found out, calling ‘fdatasync’ for each and every narinfo
cache file created by ‘guix substitute’ (and likewise for other caches)
is too expensive and pointless.  This patch series fixes that.

Thoughts?

Ludo’.

Ludovic Courtès (4):
  cache: Remove unused import.
  utils: Add #:sync? parameter to ‘with-atomic-file-output’.
  substitutes: Ignore corrupt cached narinfos.
  guix: Avoid ‘fdatasync’ call for caches and regular files.
