Hi,

the sticky bit is set on some InRelease files in my apt-cacher-ng data
directories, but not on all of them:

If this is the intended behavior, the reason should be documented
because the sticky bit on files is at least unusual.

Hallo,
* Marc Haber [Thu, Jan 06 2022, 09:49:56AM]:

Please check your setting of "FilePerms" in the configuration. That
picture can only be explained if some files were created earlier and
some files were created later, and there was a change of FilePerms value
inbetween.

That setting only gets applied to newly created files (see open(2)).

              The mode argument specifies the file mode bits to be applied when a new file is created.  If neither O_CREAT  nor

Best regards,
Eduard.

The machine was recently upgraded from buster to bullseye. No
configuration, neithre old nor new, contains a "FilePerms" setting, the
only matches when grepping are the commented example.

I'm affected too. It's not just InRelease files:

   # find /var/cache/apt-cacher-ng -type f | wc -l
   185505

   # find /var/cache/apt-cacher-ng -type f -perm /1000 | wc -l
   16447

I've never had FilePerms set in my config.
