And move all those damn security fixes that have gone into Solaris2 into SunOS 4 - some of us _hate_ svr4 and the new kernel architecture - not very easy to customize or configure/optimize the kernel at all!).eh? with solaris you an load/unload drivers and modules on the fly and configure the kernel _while_ it is running. this you ant do with sunos,
SunOS 4.1.x has facilities for loadable kernel modules. Its just that the standard distribution doesnt make use of them. (Except maybe with OpenWindows3?)
also the svr4 kernel is far more scalable than the sunos one. the case isnt that solaris kernels are harder to configure, its that they are different. if you really want to compare the two kernels read the following two books "The Magic Garden Explained" by Berny Goodheart, also "BSD Internals" (i think not sure of the author) it is published by Addison Wesley, it has a picture of a little devil on the front (i havea copy of the former and have read the latter but dont have a copy as yet).
Good advice. BSD internals book is called "The Design And Implementation of the 4.3BSD UNIX Operating System" by Lefflet, McKusick, Karels & Quarterman. ISBN 0-201-06196-1. These books describe BSD 4.3 + System V Rel 4.0, which roughly maps onto SunOS {3,4}.x and Solaris 2, but not exactly. Eg the memory management in SunOS 4.x has all changed from BSD 4.3. Also loadable modules are obviously not discussed in either book - they werent introduced until SVR4.2. Both superb books. ------------------------------------------+----------------------------------- Mailed using ELM on FreeBSD | Karl Strickland PGP 2.3a Public Key Available. | Internet: karl () bagpuss demon co uk |
