(Used to be personal and\nsystem-wide or something like that.)\n\nIf that's the case, then in a system-wide install you must be root to\nwrite to /usr/local (I'm guessing here) and there's no sudo or su -c\n'make prefix=/usr/local install' so you'd have to open an admin\nsession. Can cygwin shell be invoked under RunAs?\n\n> > - Anything else I should know?\n>\n> You would probably have great pain if on vfat. It appears to\n> work Ok on NTFS.

No linux kernel development on Windows just yet\n;-)\n\nThanks! that's a starting point, though I'm intrigued about the\npackages required.

This works just fine on Cygwin just like on\nany UNIX system.\n \n> > - Anything else I should know?\n> \n> You would probably have great pain if on vfat. It appears to\n> work Ok on NTFS. It appears to be quite slow, judging from\n> the way it runs our standard test suite.\n\nI see odd behavior when its not a locally mounted NTFS filesystem.\nFor example sometimes our SAMBA server (a Solaris system) doesn't\nplay nicely with our XP systems and we get bad error codes back\n(still haven't figured that one out). We also have what I believe\nis a Windows 2003 server whose drive is mapped onto many 2000/XP\ndesktops; that drive can't properly rename the index file so we\ncan't use it for working directory storage. Works fine though for\nbare repositories. Local NTFS has never been an issue.\n\nI see large slowdowns when the number of loose objects >~100. So I\nrepack frequently. No, defragging hasn't helped. Only repacking\nhas.\n\nI just started using merge-recur (export\nGIT_USE_RECUR_FOR_RECURSIVE=1 to enable) over git-merge-recursive.\nIts a huge performance gain. I'm glad Alex Riesen and Johannes\nSchindelin have put so much effort into it.\n\ngitk has layout issues on Cygwin. I always whack my ~/.gitk\nfile and then have to resize the window every time it launches.\nPeople have reported this bug in the past but I don't think anyone\nhas taken the time to work it out. It hasn't annoyed me enough\n(yet) to justify me spending time on it.\n\nGit pretty much works as you would expect; its just somewhat slower\nthan on a good UNIX system. Maybe its Cygwin, maybe its Windows,\nmaybe its the 4+ year old system its running on. :-)\n\n-- \nShawn.\n"},{"id":"26496","messageId":"7vwt8g2j7j.fsf@assigned-by-dhcp.cox.net","threadId":"5506","inReplyTo":"46a038f90609070018k319b748cmae7a9b30da45b3b6@mail.gmail.com","subject":"Re: Cygwin playbook?","fromName":"Junio C Hamano","fromEmail":"junkio@cox.net","sentAt":"2006-09-07T08:07:28Z","receivedAt":"2006-09-07T08:07:28Z","isPatch":false,"sender":{"key":"gitster@pobox.com","avatar":"https://avatars.githubusercontent.com/u/54884?v=4"},"body":"\"Martin Langhoff\" writes:\n\n> Sorry to ask this...
