ReiserFS is notorious for reporting slightly more disk space free than it actually has. Installing 7.2rc1 from ISO onto ReiserFS in a limited-space situation produced odd results: about a third of the way through the installation of RPMs, a message appeared listing half a dozen apparently unrelated packages (e.g. mount, one of the shells, a piece of KDE, a console game) and saying that problems occured when installing them. Unselecting a few packages (not including any of those listed in the error message) to make more space, reformatting and retrying the install resulted in no message. -- Never trust an operating system you don't have sources for.
