Nope! You *do* need to reboot in order to be completely safe. The trouble is that you can't completely unmount the root filesystem; if you try to do so, the filesystem still hangs around afterwards in a read-only state. So, you can't flush out any inode information that the kernel may have cached about the filesystem. Because of this danger that the kernel may have cached out-of-date filesystem information, it is dangerous to let the kernel write to the root filesystem after it has been fixed by fsck. That's why a reboot is necessary in such a situation. However, there should be no harm in continuing the boot process if it was a filesystem other than root which was repaired.

It's really a matter of personal taste. The HJ boot disks use xiafs as standard but SLS uses ext2fs. As an ext2fs developer I am naturally biased towards ext2fs, but they are both perfectly decent filesystems. All my tests show that ext2fs has a consistent performance advantage over xiafs, but I have heard reports from other users who claim xiafs is a little faster. Certainly, neither is much slower than the other, although I believe ext2fs does suffer less from long-term fragmentation. ext2fs has several extra features. It has fast symbolic links, and backs up superblock information to aid recovery in case of a bad filesystem crash. It has a more powerful fsck, which is capable of recovering information after a crash which would be permanently lost on other filesystems. e2fsck still has a couple of problems in the case of really severe filesystem corruption, but in these cases most other fsck's would simply fail to recover any of the lost data at all. A new, faster and more powerful e2fsck program, as well as a fs debugger to allow you to manually try to repair ext2fs partitions, are under development and are now in alpha testing. ext2fs also supports large sized filesystem blocks, and fragments for efficient allocation of space should be implemented in the future. I am working on adding transparent compressed file support to ext2fs. This is the real difference between ext2fs and xiafs - ext2fs has been designed to grow. Under constant use, both ext2fs and xiafs appear to be stable. I know of only one bug(let) in xiafs, and none in ext2fs right now. There are some filesystem problems occasionally attributed to xiafs and ext2fs, but these usually seem to be associated with either the quota patches (there seems to be some interference between the quota system and the filesystem unmounting code), and SCSI/Net interactions (it appears that under very high load, the combined DMA traffic incurred by running a high-performance SCSI card with DMA networking at the same time can sometimes cause the system motherboard's refresh cycles to get delayed to the point where memory corruption can start). Ultimately, it's up to you... :-) Cheers, Stephen. --- Stephen Tweedie (JANET: sct@uk.ac.ed.dcs) Department of Computer Science, Edinburgh University, Scotland. ------------------------------ From: predard%sunset.cs.utah.edu@cs.utah.edu (Pablo Redard) Subject: running X appl. by modem ?

Rather than argue the merits of spending more money, I'd like just one reason why someone couldn't set up a special disk for this person to use? He'd need a root disk, and a way to boot the kernel, but I see no reason that this can't be accomplished with existing tools. Alex (If I read the attrib right), how much memory do you have? This is an important question, as linux requires either 1.5 or 2 Meg, I'm not sure which. Second, how much disk space can you give to linux? would you have any problems making a partition of, say 20 Meg, and having about 1 Meg of stuff on your dos partition at the same time? Be aware, this will not be easy, as none of the packages will install from a 360K floppy, but I'm sure we can get you up. Also let me know if you have any unusual hardware. Once we get you up, you can install standard SLS stuff by copying it to your hard disk and installing it from there. It's just that first step that's difficult (actually, only getting the root partition is hard, you can easily boot off a 360K floppy). I realize I'm basically volunteering here to do a lot of work to benifit very few people (how many 386 machines have 2 Meg of ram but only a 360K floppy?), but I don't like "spend more money" answers when someone wants to try something out. -- Eric J.
