Re: Linux (was Informix running on Linux )

FreeBSD *currently* has better version control (using CVS) than most of the current Linux distributions, such as Slackware. Redhat is nice, but the 'rpm' technology they use is proprietary. I like the simplicity of Slack, but it needs better version control. I'd like to see a 'Slackable Informix' ... FreeBSD and the other BSDs are controlled by a small number of developers, whereas Linux has more planetary involvement and support, and is currently on more platforms. (Alpha, Intel, PPC, et al) As you know, Linux on Alpha (as ported by the DEC team) is a reality now, and makes the Alpha a very fast AND cost effective solution for small and large businesses alike. Excellent office suites are available for Linux, what's needed now is a good database product.
