Re: [gentoo-user] etc-update and fstab...
I don't know how feasible it'd be, but I think if the files that are getting updated could be contextually grouped that that could help quite a bit. So instead of having the list of 25 config files, there are sections A B and C where A is something like system files, be very careful here, B is startup files, you can safely update all of these, and C application files, depending on your configuration you may want to be careful here. The trick would be being able to select -5 for group B, then -3 for group C, and then hand walk group A, or some such combination. Anyway, just a thought. If this isn't doable with the current structure, feel free to toss it aside. Sean signature.asc Description: This is a digitally signed message part

[gentoo-user] etc-update and fstab...
Hi, I emerge some ebuilds yesterday, and then i got a warning that I should run etc-update to merge some files. I used the -5 option which automaticall merge the files, and it seems it deleted some of my config files such as /etc/fstab. The result is that I cannot boot gentoo anymore. Pretty bad... I guess i missed something with the use of etc-update. How should we use that tool? Hopefully i can boot a different version of linux and access to my config file for gentoo by mounting the partitions. I tried to recreate my /etc/fstab but my system cannot boot. It complains with the something like: Mount proc at /proc The mount' command failed line 14 in /etc/fstab is bad [mnent] line 15 in /etc/fstab is bad Note 1. I commented the line /dev/hda1 but if i uncomment it i get the same problem. Note 2. My gentoo is installed on my disk /dev/hdb, but lilo is on hda1-- hda is the disk where i have my other version of linux. it worked welll before I got this problem with etc-update.

Very carefully. Like any other tool that can affect how you machine runs you should make sure you understand WHAT the tool will do before actually do it.

After I have done the files I have modified I simply use the -5 to replace the resto of those files. Nowadays those -5 handles files are quite few, becuase portage is automerging so much of the stuff. PS. I do use ~x86 keyword to get the testing stuff in my system. -- [EMAIL PROTECTED] mailing list

A few points: (*) emerge says I didn't overwrite your config files in case it would change any important settings - I've left it so you can see whether the changes are good or not (*) you told etc-update just blindly overwrite the config files - I don't care (*) you complain that things don't work any more Think on that for a moment... This is IMO the most very frustrating part of the way Gentoo works. You mean that it doesn't tie your hands behind your back to stop you shooting yourself in the foot?

Usually a mix of r and l is all that's needed. (*) Select 1) Replace /etc/fstab with merged file Or you can start with the gentoo life cd, mount the partition and edit fstab.

This is not entirely correct. There was an update to /etc/fstab recently which included a minor change. The change was to the /dev/shm line and changed the first section from tmpfs to none. Albeit this is only a minor change, but major changes could take place. If those changes are made available through portage then there is no need for any user to be subscribed to a mailing list, scan forums, etc. to be notified of the change.

What are some of the major changes to /etc/fstab that could occur? The only thing I can think of is the renaming of fs types in the kernel (unlikely) but sed would be better suited to do this instead of replacing or actively merging differences. No matter which way you do it through etc-update you'll still have to edit the file manually. Actually, the other thing is the device paths could change, but here again you would have to use sed or edit the file manually because you cannot count on the user's system having the same mount / dump options or mount points. -- [EMAIL PROTECTED] mailing list
