That's fine by me. Where should I post comments about the config? Here? |
| 6 |
|
| 7 |
Power management: Should we be turning on all of the power management |
| 8 |
for everything? I only ask this because the Gentoo LiveCD is more of a |
| 9 |
build/rescue environment than a live demo. For example, I can see the |
| 10 |
reasoning for turning on ACPI, but not ACPI sleep. The same can be said |
| 11 |
for CPUfreq (which you have disabled). |
| 12 |
|
| 13 |
Block devices: CONFIG_CISS_SCSI_TAPE? Tape drives? Why? For rescue |
| 14 |
purposes? Should we not then include any number of tape software? I |
| 15 |
can see reasons for it, but I tend to think that it just is another set |
| 16 |
of modules to compile/store on the CD that will rarely if ever be used. |
| 17 |
At the very least make it a module. You definitely want the DAC960 |
| 18 |
module (CONFIG_BLK_DEV_DAC960) to support Mylex RAID controllers, which |
| 19 |
are quite common. |
| 20 |
|
| 21 |
IDE: Turn on the CONFIG_IDE_TASK_IOCTL, at least. This is invaluable if |
| 22 |
Gentoo LiveCD's are to be used as rescue discs. Also, should we include |
| 23 |
the chipset drivers which require special kernel parameters? I'm not |
| 24 |
opposed to it, just asking. |
| 25 |
|
| 26 |
SCSI: CONFIG_BLK_DEV_SD should be a module, since it isn't required to |
| 27 |
boot the livecd. The same can be done for CONFIG_BLK_DEV_SR, since none |
| 28 |
of the SCSI drivers are compiled in statically, and doscsi is required |
| 29 |
to load them all anyway. Is there a reason why you chose to enable |
| 30 |
attributes (CONFIG_SCSI_SPI_ATTRS)? Why not CONFIG_SCSI_AACRAID or |
| 31 |
CONFIG_SCSI_MEGARAID? How about CONFIG_SCSI_GENERIC_NCR5380, |
| 32 |
CONFIG_SCSI_IPS, CONFIG_SCSI_INIA100, CONFIG_SCSI_PPA, |
| 33 |
CONFIG_SCSI_QLOGIC_1280, CONFIG_SCSI_QLA21XX, CONFIG_SCSI_QLA22XX, |
| 34 |
CONFIG_SCSI_QLA2300, CONFIG_SCSI_QLA2322, CONFIG_SCSI_QLA6312, |
| 35 |
CONFIG_SCSI_QLA6322, CONFIG_SCSI_SYM53C41, or CONFIG_SCSI_DC395x? |
| 36 |
|
| 37 |
Networking: There's no need for CONFIG_NETFILTER on the LiveCD. |
| 38 |
CONFIG_IPX? I can't see a reason for this IPX. CONFIG_TUN either. |
| 39 |
|
| 40 |
Input: CONFIG_INPUT_TSDEV_SCREEN_X and CONFIG_INPUT_TSDEV_SCREEN_Y |
| 41 |
should probably be 1024 and 768 since the defaults are to use a 1024x768 |
| 42 |
framebuffer. Also, turn on CONFIG_INPUT_JOYDEV, since you turn on the |
| 43 |
game port below. I would also leave all of the game port modules, |
| 44 |
simply due to some really strange input devices out there which can use |
| 45 |
the game port. That and if we get together, we can make a single kernel |
| 46 |
for both LiveCD and GameCD, which would make bug fixing easier. |
| 47 |
|
| 48 |
Joystick: Turn on CONFIG_INPUT_JOYSTICK and set everything else as |
| 49 |
modules. Be sure to turn on the IFORCE support, too. |
| 50 |
|
| 51 |
Serial: CONFIG_LEGACY_PTYS is not needed, as CONFIG_UNIX98_PTYS support |
| 52 |
is already enabled. It won't hurt anything, it is just redundant. |
| 53 |
|
| 54 |
IPMI: Necessary on a LiveCD? |
| 55 |
|
| 56 |
Watchdog: Necessary on a LiveCD? |
| 57 |
|
| 58 |
Character: You want CONFIG_RTC if you have CONFIG_SMP. |
| 59 |
|
| 60 |
AGP: Set it all as modules. I use it on the GameCD, and it allows for |
| 61 |
a much nicer X on any X CD that we may produce. The same for DRM. |
| 62 |
|
| 63 |
I2C: Necessary on a LiveCD? |
| 64 |
|
| 65 |
Sound: Definitely compile this as modules. If you want an exact list |
| 66 |
of what to do, I'll provide one. The scripts that I have for the |
| 67 |
LiveCD's already work great with ALSA, so I would enable that. You will |
| 68 |
need to leave CONFIG_SND_MIXART unset, or at least I could never get a |
| 69 |
kernel to compile with it enabled. |
| 70 |
|
| 71 |
USB: CONFIG_USB_HIDDEV should be enabled only because it is the |
| 72 |
"generic" interface to USB and is needed for some USB monitors. I don't |
| 73 |
think there's a need for CONFIG_USB_MDC800, CONFIG_USB_MICROTEK, or |
| 74 |
CONFIG_USB_HPUSBSCSI on a LiveCD. I also nee no need for |
| 75 |
CONFIG_USB_DABUSB. I think you only need CONFIG_USB_SERIAL=m and |
| 76 |
CONFIG_USB_SERIAL_GENERIC=y under the USB Serial. Everything else is |
| 77 |
related to hardware devices which we will not have software available |
| 78 |
for on the LiveCD. |
| 79 |
|
| 80 |
File systems: Don't enable CONFIG_NTFS_RW as it is completely useless. |
| 81 |
Don't enable CONFIG_DEVFS_MOUNT as the init scripts take care of it in a |
| 82 |
much cleaner (for Gentoo) manner. You should enable CONFIG_SMB_FS, so |
| 83 |
people can read files from Windows machines. |
| 84 |
|
| 85 |
CryptoAPI: CONFIG_CRYPTO_AES must be set for encrypted loopback. |
| 86 |

I haven't run across one yet, but I'm not going to discount the |
| 92 |
possibility. |
