Hi, new to Linux (couple months and new to this forum)

already In grub after a couple of months I have 3 versions of fedora 3.
due to kernel updates through Yum.
What steps do I need to take to clean up the older versions of the kernel as far as routine maintenance of my system.
I assume I can edit the reference to older ones out of grub.conf, but also what old kernel files can I/Do I need to clean up and get rid of?
thx , dan

experimenting with the kernel is a serious issue..........i usually have bad luck when it comes to compiling a new kernel

i don't really know how you can clean the older version............i know that each kernel version has its own two or three folders named after the version...........i guess all you do is just delete the folders........not sure though
--------------------------------------

the safest way to get around kernel problems is to make an image of your root partition, before compiling a new kernel...............you can use norton ghost for instance..............place that image in a safe partition.........then you can restore your old system withing 5 min or less, in case you damage your system

i do this for windows with ntfs partition............i don't know if norton ghost can recognize ext2/3 partitions

no, I am not compiling it myself. I am just allowing yum to do the update.
I suspect there is also probably commands to make Yum clean up the older kernel just don't know what it is.

husnos, that is such overkill to be "safe". All you need to do is save your old vmlinuz image as a seperate file before copying over the freshly compiled one. Then edit your boot manager (such as lilo) to point to each image, that way if your new one doesn't work you can fall back to the old one. Saves having to do all that extra (unnecessary) work.

Daniel49, if you look in /usr/src/ you can see each linux-x.x.x folder, as well as a linux folder symlinked to one of the versioned ones. I've safely removed an older version folder here completely and had no problems. Just make sure your new kernel is working 100% as you expect (try plugging in USB devices, test sound and graphics drivers, etc.)

Hope that helps.

ok, heres what I see :

inside /boot I have config-original ver
initrd-original ver
systemmap-original ver
vmlinuz-original ver (4 files)


all of the above first kernel update (4 files)
and finally all of the above 2nd kernel update. (4 files)

inside of /usr/src there are no files.

so if I delete the reference in grub to original and delete the config-orig,initrd-orig,system map-orig, and vmlinuz-orig.
that would that be safe and all the cleanup that is necessary?
last 2 updates seem stable by the way.

the thing is restoring an image located on hardrive takes less than 5 minutes.............

All you need to do is uninstall the old kernels. When you uninstall them, their grub entries are automatically removed. Do
A list of installed kernels will be listed, uninstall the ones you don't need by doing
