I\ncan't remember the exact invocation, but you echo the sha1 of the\ncommit you want to be the oldest commit to .git/info/grafts, then run\ngit-filter-branch.\n\nYou can use whatever you like to discover that sha1, e.g. keep N\nrevisions (which might be committed once per day) around, or have some\ncustom time limit etc.\n"},{"id":"179429","messageId":"20111114142525.GB8641@external.screwed.box","threadId":"28925","inReplyTo":"CACBZZX5kBqM1eye40_Vw0W=8qnNsUQBVCE0q9JrixYomGPuZbg@mail.gmail.com","subject":"Re: delete deprecated refs to release disk space","fromName":"Peter Vereshagin","fromEmail":"peter@vereshagin.org","sentAt":"2011-11-14T14:25:25Z","receivedAt":"2011-11-14T14:25:25Z","isPatch":false,"sender":{"key":"peter@vereshagin.org","avatar":"https://gravatar.com/avatar/27a92b8c80743df8621433ca040657c4ac37a78497228d04f703e70731c5f30b?d=mp&s=160"},"body":"Hello.\n\n2011/11/13 18:01:18 +0100 ??var Arnfj??r??
