Not "all programs". The option is intended (at least it is documented as such) for backup-programs. In my book rsync qualifies as a "backup-program". In my case there are exactly 3 programs touching my mail files. procmail -> delivers them (sets mtime) mutt -> reads them (sets atime) rsync -> syncs them (and currently destroys atime) So the only program that interferes with my perfect(tm) world is rsync. ;-) I once wrote to the mutt-maillinglist why mutt doesn't set atime explicitly, so that it works even on noatime-mounted filesystems, but i was totally ignored.

Could you give me a hint, so i can patch my local rsync? Bis denn -- Real Programmers consider "what you see is what you get" to be just as bad a concept in Text Editors as it is in women. No, the Real Programmer wants a "you asked for it, you got it" text editor -- complicated, cryptic, powerful, unforgiving, dangerous. -- To unsubscribe or change options: https://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
