Re: Modification date of /gnu/store files is 1970-01-01
Good to have you! A mention and description of purely functional package management ideas I think would be very welcome in the documentation. Good luck, John
Re: Modification date of /gnu/store files is 1970-01-01
Tobias, John, thank you for this explanation! My first thought was… oh, something broke during my installation. But I was only spoiled by not resetting my mind from the usual suspicious package managers. Next time I will think more about the nature of using a purely functional system, of course it makes sense. Do you think it is worth to spend a sentence about this in the documentation (I must have skipped this if it is already there)? And, by the way, thank you for the warm welcome! I fully believe in the concept and philosophy, so count me as a new user, ready to stay. Kind regards, Martin

Hello and welcome Martin! The Unix time stamp is set to 0 for one thing to ensure reproducible builds. If two build artifacts suffered in time stamps, they would be considered different. Hope you find guix helpful and hackable, John

Martin, Martin Michel 写道: So far so good, but I could not figure out what is wrong with the file system entries of /gnu/store. All entries there have a timestamp of UNIX epoch 0. Well spotted! This is intentional. The Guix daemon[0] changes all timestamps of all files added to the store to a known value. Same for other metadata like ownership and some permission bits. If it did not, certain software could (and does) behave differently between two different machines with otherwise identical stores.
