So I added [OT] to the subject. Off-topic? I don't think so, it's very much relevant for Debian, but a change of subject would be useful to attract more attention to it ;) So the question again: When mounting a tmpfs on /tmp systemd sets 'strictatime'. I was wondering whether this is really needed. Does anybody know of software that would break with 'relatime' (the default) or even 'noatime'? I'd be happy to RTFM if anybody can point me to the relevant FM.
