[SOLVED] Gentoo Install misc question

[SAngeli]

Hi,

I have few questions reguarding gentoo install I wish to clarify:

1. After customizing my kernel, I always issue this command: make && make modules_install
I have seen this command line: # make && make modules && make modules_install && make install and wish to comment on this.
Question: is it true that make modules applies to older kernels (< 2.6.9) and that for kernels > 2.6.10 you can just issue make && make modules_install?
Question: What is the purpose of make install in this kernel concept? Will it copy into /boot partition?

2. Mount the proc filesystem. Usually I do mount -t proc none /mnt/gentoo/proc. Additionally, I have also seen doing cp /proc/mounts /mnt/gentoo/etc/mtab
Question: What is the second command for and is it needed or not?

3. Hotplug and Coldplut. I usually set them as:
# rc-update add hotplug default
# rc-update add coldplug boot
Question: Is this correct? I have seen starting coldplug default. Should it be boot because it is the first thing needed at boot for detecting plug devices?

4. In /etc/conf.d/hdparm, when setting customized settings:
disc0_args="....."
cdrom0_args="....."
Instead I have hda_args="...." and hdc_args="...."
Question: Is it better / ok to replace disc0 with the exact device or not or does it not make a difference? If not, what is the sequence for CD-ROMs: cdrom0 cdrom1 cdrom2 ... ; same for disc0 disc1 disc2 .... Correct?

5. Grub.conf.
Is it possible to split instructions in lines (beause it does not fit all in one line and therefore "difficult" to read)?
Example:
kernel (hd0,0)/vmlinuz ro root=/dev/hda3 video=vesafb:ywrap,pmipal,1024x768-24@85 splash=verbose,theme:emergence
initrd (hd0,0)/fbsplash-emergence-1024x768
Question: Can I split it like this? Please advice on where exactely I can break the line or maybe it does not make any difference?
My Example:
kernel (hd0,0)/vmlinuz ro root=/dev/hda3
video=vesafb:ywrap,pmipal,1024x768-24@85
splash=verbose,theme:emergence
initrd (hd0,0)/fbsplash-emergence-1024x768
Can this be done?

6. Fstab
Can I have as CD-ROM line /dev/hdc1 or should I have /dev/cdroms/cdrom0
I learned somewhere that I can replace the /dev/cdroms/cdroms with whatever dmesg displays as the /dev device of the IDE item.

7. Make.conf
When i have to go to a new line to line up all settings, I do (for USE) as follows:

Wow that a lotta questions. Let see.....
1a) Yes it only applies to older kernels, hence you answered your own question with that ^_~
1b) I believe it for people that use LILO instead of grub but I'm not entirely positive on that matter

3) Hasn't the hotplug script been removed? I coulda sworn that the hotplug init.d script was removed recently. Might want to check around on that. As for coldplug, you probably want it in boot for the reason you state. That's where I have it as well.

4) As far as I can determine it makes no difference. If you like the hda better than disc0 (which is more grub like I suppose), then just use it ^_~

6) You can do that, but you'll make your life a bit easier down the line by using the /dev/cdroms links instead. It just makes it a bit more clear as to what device you're talking about. The idea being that if you move the cdrom around on the ide chain because you bought a new HD, you wouldn't have to modify the fstab for the CDRom.

7a) Yes you must have the \ on each line (except for the very last line, i.e. the one with the closing ")
7b) For every option that is textual, you can wrap it in quotes safely. For options that are numerical, you shouldn't wrap those in quotes. As for grub, I don't think that applies. Been a while since I've had to mess with my grub config so my mind is a but fuzzy on that one.
