I have started doing regular automated builds of Mercurial, and packaging up the results for Fedora Core 2 and 3. These builds are performed four times a day, and the results are available here.
Due to the vagaries of my local setup, I have i386 packages available for FC2 and FC3, and x86_64 for FC3 only.
The easiest way to install them is using the yum package manager. On FC2 systems, add the following to your /etc/yum.conf file. On FC3 systems, add it to a new file named /etc/yum.repos.d/mercurial.repo.
[mercurial-snapshots] name=Mercurial Snapshots FC$releasever $basearch baseurl=http://www.serpentine.com/hg/rpm/fedora/$releasever/$basearch/ gpgcheck=0 enabled=1
I haven’t installed FC4 on any systems yet, so no builds. Sorry.
