hello,
i'm working on a file monitoring system and I'm noticing files like the
following example being created and then disappearing:
/usr/share/zoneinfo/right/Europe/Zurich;56177f7a
/usr/share/zoneinfo/right/Europe/Bratislava;56177f7a
/usr/share/zoneinfo/right/Europe/Prague;56177f7a
/usr/share/zoneinfo/right/Europe/Belgrade;56177f7a
/usr/share/zoneinfo/right/Europe/Ljubljana;56177f7a
/usr/share/zoneinfo/right/Europe/Podgorica;56177f7a
/usr/share/zoneinfo/right/Europe/Sarajevo;56177f7a
/usr/share/zoneinfo/right/Europe/Skopje;56177f7a
/usr/share/zoneinfo/right/Europe/Zagreb;56177f7a
/usr/share/zoneinfo/right/Europe/Belfast;56177f7a
/usr/share/zoneinfo/right/Europe/Guernsey;56177f7a
/usr/share/zoneinfo/right/Europe/Isle_of_Man;56177f7a
/usr/share/zoneinfo/right/Europe/Jersey;56177f7a
/usr/share/zoneinfo/right/Europe/London;56177f7a
/usr/share/zoneinfo/right/GB;56177f7a
/usr/share/zoneinfo/right/GB-Eire;56177f7a
/usr/share/zoneinfo/right/Etc/UTC;56177f7a
/usr/share/zoneinfo/right/Etc/Universal;56177f7a
/usr/share/zoneinfo/right/Etc/Zulu;56177f7a
/usr/share/zoneinfo/right/UTC;56177f7a
The sample above happened during a tzdata package update. Does rpm
create these files and then moves them to destination (over the old file
during an update)? Or, does it move the old file to files in the format
above and then deletes them when the new file install is completed? If
so, how does it determine the "suffix" string, like ";56177f7a" in the
above samples? Is it randomly generated? What's the nature of this
suffix string? Is it always 8 characters wide? it seems to allow for
alphanumeric characters, but does that include capital letters? Are any
other characters allowed in the suffix string?
If I can understand this better, I can write rules to categorize them as
being part of some RPM activity. Just need to understand what they are,
and what kind of patterns I can look for.
Thanks,
Bond
