I still think it is better to arrange shared swap spaces after installation of a new system. Yes, the installer could offer the option to format or not format a swap space. Certainly, if the installer creates a new swap space, it must be formatted. For an existing swap space... it's more complicated. Must the installer ascertain whether an existing swap space is correctly formatted? Should the installer offer a facility to set priority values for swap spaces used by the new system? What about page size? I am no expert (well, maybe a modest expert), but I think linux supports four page sizes on Intel processors: 4, 8, 16, and 64 KBytes [see: arch/ia64/include/asm/page.h]. Swap spaces must be formatted for the appropriate page size. Rather than ask the installer to handle an issue this complex, which can readily be arranged after installation, I prefer the installer be limited to things that cannot reasonably be done later. If the installer permits a request to include a swap space without formatting it, it should refuse if this existing swap space cannot be used by the kernel it will install. Without this check, it seems all to easy for a user to think he has a swap space when it actually will not be used. I must admit I have never tested how astute the Fedora installer is about swap spaces. Maybe it is terribly clever, and everything always comes out right. I'll try a test the next time I install. -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
