The /dev/hda1 is labeled as /boot if queried by tune2fs -l for fc6, or by querying /dev/sdb1 from f8. /dev/sda1 on the new drive was labeled /boot1 by the installer and once booted, is mounted as boot. The manpage for tune2fs doesn't say if there is supposed to be a '/' in front of the label, and booted to fc6 I get: [root@coyote mnt]# tune2fs -l /dev/hda1 tune2fs 1.39 (29-May-2006) Filesystem volume name: /boot And [root@coyote mnt]# tune2fs -l /dev/sda1 tune2fs 1.39 (29-May-2006) Filesystem volume name: /boot1 plus [root@coyote mnt]# tune2fs -l /dev/hdd3 tune2fs 1.39 (29-May-2006) Filesystem volume name: amandatapes Now the difference I see there is the missing slash cuz I didn't use one, so I'll relabel it with the slash and try rebooting. If that fixes it, then maybe the requirement for the leading slash should be noted in the manpage? >> Linux likes to claim it doesn't have a single point of failure.

There are about 2 tons of reference books on the shelve above me John, but many are as dated as I am even if they are 40 years newer than me. I've found the manpages to generally be more helpfull, as is the right question asked on the right list. Unforch, while english is my native and only tongue, it appears my question syntax often confuses. >And reading a book can lead to a quick education, consumed at your own >comfortable pace. Some books I have read literally overnight, some I >pick the most important bits out of and never read the entire tome >because it's not all relevant. Very very true. Add in the fact that over the years, I have been more hardware oriented than software, I didn't start coding for an 1802 till the later half of the 70's. No assembler in those days, just look it up in the programmers manual from RCA, and enter the next hex value while running the hex monitor on a Quest Super Elf board. Frankly, I prefer to be a little closer to the hardware than we get today with our 'modern' tools. >A good introductory book on Fedora would answer most of the questions >you've asked here, including how to mount the filesystem rw. The local Borders is dropping the ball in terms of keeping those shelves up to date. I don't believe there is anything there for FC7 or F8. >There's a good reason to mount it ro by default, that is exactly what >you want if you have to do a filesystem check. If there's disk >corruption, and you start out writing willy nilly to the disk, _ouch_. True, but if I go back into the grub stanza and change the ro to rw, I fully expected it to listen to my wishes. It has a couple of times before in years back up the log, I fixed an FC2 problem that killed booting that way, but now it apparently ignores that option. >I would also expect the book to cover lvm, the basics of virtual >consoles and logging in on one, system logging, package management and >building software yourself. The latter I'm no stranger too, I've packaged my own Gutenprint because fedora won't (at least not for FC6), and I'm currently running kernel 2.6.24.-rc5, and I have to say its scheduler is a hell of a lot smoother than the one in 2.6.23.8 whatever for F8. The difference is obnoxiously clear regarding that aspect of multitasking. >It's also worth reading the RHEL5 manuals, they're online at Red Hat and >CentOS. I wasn't aware us peons running fedora could access those. Thanks John. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
