[gentoo-user] Multilib wrapped headers with amd64/no-multilib profile?
Hi,
In Gentoo Prefix on amd64 host with a no-multilib profile, for
packages that inherit multilib multilib-minimal, the multilib-build
eclass wraps headers as if multilib were enabled.
One example is mpi.h header in sys-cluster/openmpi. I am using a custom
modified ebuild, but the differences shouldn't be relevant to this issue.
The wrapper is causing problems for me, for reasons that are not
relevant here [1]. This question here is whether the wrapping should
takes place at all with no-multilib profile.
Wrapping happens on amd64 with this profile:
gentoo:default/linux/amd64/17.1/no-multilib/prefix/kernel-3.2+
For reference, as expected, no wrapping happens on ppc64le with:
gentoo:default/linux/ppc64le/17.0/prefix/kernel-3.2+
The above profile is a parent of my custom profile but this shouldn't be
relevant, the custom profile is simple, it just sets compiler flags,
package lists, use flags.
Diagnosis: multilib-build.eclass wrapps the headers because it is
detecting the "abi_flag" as set. So, as far as I understand, it
(wrongly?) ends up on the code path for yes-multilib instead of
no-multilib:
multilib_prepare_wrappers()
...
if [[ ${MULTILIB_WRAPPED_HEADERS[@]} ]]; then
# If abi_flag is unset, then header wrapping is unsupported on
# this ABI. This means the arch doesn't support multilib at all
# -- in this case, the headers are not wrapped and everything
# works as expected.
^ I want the case described in this comment, but not happening
if [[ ${MULTILIB_ABI_FLAG} ]]; then
^ this is set to abi_x86_64.amd64...
...because MULTIBUILD_VARIANT is set
...because MULTIBUILD_VARIANTS contains the flag
...because multilib_get_enabled_abi_pairs() adds it there
...because 'use abi_x86_64' evaluates to true
...presumably because in gentoo/profies/sarch/amd64/
A. use.force contains abi_x86_64, and/or
B. make.defaults sets IUSE_IMPLICIT="abi_x86_64"
Workaround: override in my derived profile:
1. in make.defaults: USE="-abi_x86_64"
2. in use.force: -abi_x86_64
Then, 'use abi_x86_64' evals to false and the header is not wrapped.
Before digging deeper, I figured I'd ask whether this is by design to
end up doing multilib things with no-multilib profile, or if it's some
issue with the way the ebuild is using multilib eclasses. What is
the correct way to disable multilib for good? Thanks for any insights.
[1] The wrapper does not cover the case when Clang is passed -target
le64-unknown-unkown-unknown, which doesn't set the macros for x86_64
that the wrapper checks. I'm not faulting the wrapper, though.

[gentoo-user] Webserer monitoring tools
Hi List: I have just purchased a refurbished PC - PIII, 450, 128mb ram, Network card, 10GB. Also just purchased Broadband connection (2mb's, upsteam 288kbps) I want to use the machine as a webserver over the broadband. and host my own site (which currently runs on a free ISP) As it's a low spec machine and I don't want the website to run totally crap, I'm thinking to use Gentoo's flexibility and speed to install it as a totally dedicated webserver(Apache,PHP,PERL). As long as it can take about 6-8 users on at a time without struggling this will be fine. Does anyone have any advice about monitoring software/apache modules that I can use to check how many connections, connection speed, resources (CPU) so I can monitor how the webservers doing, if it's getting overloaded etc. Hope this is an appropriate forum (I've just subscribed so not sure), if not any suggestions.

What are the most common forms of attack and how do I avoid being attacked by one of them? The services avaliable are only Apache - SSL and SSH. I've installed an firewall, iptables and firestarter to control it, and blocked all ports except 443 and 8080, where the SSH is listening. Apache has PHP installed as a module. Want to know how secure your server is? Try and hack it! A good port scanner like nmap should be a basic check of your firewall. I would also set nmap (if it can do this) to perform a SYN flood as it scans, to see if your server can withstand that basic DoS attack. (Adding --syn to your TCP rules in iptables can prevent SYN flooding when used with SYN cookies.) When you break in, find out why it worked and how it can be patched. Some things I would advise (I'm currently working on a server at the moment as well): - If the server is really important (or if you're paranoid), use the hardened-sources with PIE/SSP to prevent badly-written programs from arbitrarily executing code. - Enable SYN flood protection. There's a kernel option somewhere about IPv4 SYN cookies, enable that, and couple it with --syn attached to your TCP rules in iptables. It's a very popular denial- of-service attack. - Whenever you need to login or authenticate yourself, make the system delay five seconds after a bad password is entered. This will make a brute-force attack much much slower (0.2 passwords/sec as opposed to millions passwords/sec without a delay, depending on your server's speed). - Make sure iptables is set to deny all traffic that isn't explicitly allowed. - Turn off any services you don't need. - Read through your logs every now and then. I highly advise having the server burn them to a CD/floppy every now and then for an instant backup. Get a log reader/parser, too. Naturally, hide the server in the attic or basement. Chain it to something, or if it has a security slot, use a security cable. Put a lock on the case door. Unplug your floppy/CD drives if you're not using them.

What CFLAGS are recommended for a dual core CPU and what precautions must one take to have the SATA HD recognised by the install media? I don't think the CPU is 64 bit in case you need to know. A multi-core single-CPU system (yours) is virtually identical to a single-core multi-CPU system. I would use MAKEOPTS=-j2 or higher (basically, twice what you would do for a single-processor system) in your make.conf to take advantage of all that parallel processing power. Use the normal CFLAGS and CXXFLAGS, there aren't any special options for multiprocessor systems there. When you compile your kernel, be SURE to include SMP (symmetric multi-processing) support to let the kernel use both cores. SATA hard drives, if supported natively by the southbridge, require no extra drivers. Since your motherboard must be relatively new, this is your case. If they aren't supported natively, one of the various sata_* modules will autoload and handle it. They might be enumerated as SCSI devices, though (/dev/sd* rather than /dev/hd*), but I believe this is perfectly normal. -- Colin -- gentoo-user@gentoo.org mailing list

Just remember, if the laptop isn't going too far, a good length of Ye Olde Cat5e is a much cheaper solution. That being said... Yeah, I picked up a great Orinoco (branded as Enterasys) at Rokland.com last month for roughly $50. Atheros chipset, 802.11a/ SuperA/b/b+/g/SuperG... very nice. It works in Windows (with the driver CD), Mac OS X (with the shareware OrangeWare driver--totally worth the $15 shareware fee) and, naturally, Linux (with MADWIFI). It picks up Channels 1 through 14, and can put out up to 100 mW of power (40 mW on A networks). There's no antenna jack, though, but I hear most PCMCIA Orinocoes can be modded to include some kind of external jack; I'm not that desperate for power, but with dial-up at home, I might do that mod and build a yagi antenna, get in my car, and... well, you get the idea. :-) Still haven't had any luck with KisMAC (the OS X port of Kismet), though.

The best is to buy from a store with a liberal return/exchange policy...of course it always helps if it says supports linux on the box! Yeah, if you've listened to this list, you'll know some chipsets are good, and some are just plain bad. Bad chipsets (Broadcom, PrismGT, ACX100, ACX111) are not supported well if at all under Linux. (Hell, even Windows choked on a Windows-only ACX111 card.) You may have success with the Windows drivers and NDISwrapper, but more than likely this is one for shipping back to your e-tailer. These chipsets being el cheapo, they pop up in a lot of low-end consumer wireless devices. Good chipsets (Atheros, Atmel, Intersil, Orinoco, Prism, Prism2) are natively supported by Linux, and most of them can be loaded from the LiveCD with the modprobe command. The rest are usually supported by building in support when you build the kernel. Sadly, these are more expensive because all the hardware is on the card, and nothing is emulated via a driver (remember Winmodems vs. hardware modems? This is it all over again.) But you do get what you pay for, as a lot of enterprise-level solutions have these chipsets, and they boast excellent reliability, compatibility and range. Any other chipset, just Google. Some manufacturers stick to one chipset (like Apple does Broadcom). However, most manufacturers often change chipsets during production without warning, keeping the same model number and just tacking on a Revision B, often written on the card only but most do write it on the box in tiny print. Just wait until no one's looking and open up the box and check :-) As for supports Linux, there are far too many distros, drivers, hacks and configurations to test with. Maybe they tested Debian with MADWIFI? Slackware with NDISwrapper... and which Windows driver? If it says Linux compatible, don't take it as a green light. Take it as a yield sign instead--look first, then go. If you've got a laptop, bring it and a LiveCD to the store (if you don't buy it online) and give it a whirl... with permission, of course.

It should be right next to the mic jack. In most color schemes, it's usually the blue one (red=mic, green=out); read the labels if you're not sure. What file formats do standard CD players play ? I would guess mp3 but there do not appear to be any mp3 encoders for linux, ogg would be great but I doubt that it would play. Standard CD players play waveform audio (WAV), but I believe it needs to be aligned to the CD block boundaries. However, you'll need to burn it as an audio CD, not a data CD, otherwise it will be unreadable to the CD player. Most CD players nowadays can play back MP3 data CD's but there's no standard, not even a de facto one, for this. Dare I say it? Most people do have computers, so if your local group doesn't make Learn [subject] While Driving tapes, it may be cheaper and easier to simply forgo the physical medium and stick them on a web server for downloading/streaming/podcasting. MP3's of people talking don't require the higher bitrates that music does, so you can drop the bitrate and change it to mono (one-channel audio) to save some server space/bandwidth. Can anyone suggest an application to get the files from the tape change them into said format ? (Simple is good, I dont need a recording studio :)) Anything that can listen to your card's line-in will do. I haven't done it on Linux, but on Windows/Mac OS X, pretty much any program will do it. As for burning, most programs that can burn an audio CD take MP3/WAV/OGG/WMA/AAC files (your choices may vary depending on the app) as input and do the conversion themselves behind the scenes before burning. -- Colin -- gentoo-user@gentoo.org mailing list

I am not sure if this will give a tremendous speedup. Granted, the source files won't need to be read from disk, which is an advantage, however, the file reading time should be very small compared to the time it takes for the compiler to translate the source code into machine code. Also, there's the ammount of memory you will lose, memory that could be used by the compiler. In some cases, gcc can eat very big chunks of memory. Not to mention the OOo ebuild needing around 3GB of space in TMPDIR, so this approach would only result in the emerge failing quicker. Not if you've got a machine with more than 3 GB of memory. A dual-proc Power Mac G5 can handle up to 8 GB of physical RAM. If you did this trick on one of those, you might see some serious improvement! But with most PC's being limited (by the x86 and motherboard designs) to 2 GB of physical RAM, it wouldn't work with large apps. A good suggestion would be to grab some old computers, Gentoo-ize them, network them over 100BaseTX or Gigabit and make a little distcc farm.

Sometimes inserted card could be any of sdb[1-15]. Udev helped with this a little, but basically the reader was a POS (for you wtf users). I'm looking for something that will react the same every time. Any recommendations? I've got an AFT PRO-9. It's a 9-in-1 connects via USB 2.0 internally/externally and has Secure Digital, Multimedia Card, SmartMedia, xDigital, Memory Stick, Memory Stick Pro, CompactFlash, MicroDrive and a 4-pin FireWire 400 port (pass-through, you need a FireWire port somewhere on your computer). I've only tested it with an SD card, and it seems to work perfectly. To use this, you need to compile in SCSI support (the same you need for USB Mass Storage) and make sure you select the Probe all LUN's option. -- Colin -- gentoo-user@gentoo.org mailing list

I currently have my system installed on 2 40GB IDE drives. They are in an LVM volumegroup, and the 2 drives are striped. What i need to do is transform this striped disk cluster into a mirror. (preferably using the most cheapest and painless method). I kind of know my way around LVM, so i don't really need a _totally_ detailed answer, but i need to know, if this that i am trying to accomplish is a) possible b) what are the steps that i should follow in order to do this? I was thinking like this: use pvmove or something to move all of the pv's from one disk to the other, then reduce the volumegroup (remove the disk eg physical volume from it) add it as a mirror... Seems to me the best way to do this would be a third Disk. Is this an option?? Personally, I'd just get two more disks and turn it into a RAID 0+1 setup. If you've got the space, the money and the Molex connectors, I'd go for it. Or just get one more disk, backup your data, create a three-drive RAID 5 volume and then copy it all back. RAID 0+1 would be easier to setup, require much less overhead and have more fault-tolerance than a three-disk RAID 5 setup. However, it's more expensive (you need two more disks instead of one more) and it's not as cool-sounding as RAID 5. :-P -- Colin -- gentoo-user@gentoo.org mailing list

In fact, in the BIOS setup, it refuses to let me specify the hard drive as a boot option. Anyone have any idea why? Is there a BIOS update available? Grab the update and put it on a floppy/CD, and flash your BIOS to the latest version. You might have a bug in your BIOS. One of my motherboards' BIOSes didn't support hard drives 32 GB, but the patch included an error in autodectection, causing my 60 GB hard drive to appear as 2.1 GB in the BIOS when set to LBA mode. Gentoo didn't have any problems with it, even without hdx=stroke, so I think that was just a display error. But the update was well worth it, anyway. A more obscure BIOS tactic common back in the day was to put all or part of it in a hidden area on the primary master hard drive.

[gentoo-user] Reboot when GRUB starts
This is really annoying. I just finished a Gentoo install on my computer and rebooted after installing GRUB with the command grub-install --root-directory=/boot /dev/hde as stated in the Handbook. Right after GRUB loads the stage1.5 file, the system reboots. The first partition is active. Marking partition 2 as active can't get me into Windows, though, so I'm kinda screwed ATM. I created my Gentoo partitions by resizing my NTFS partition with PartitionMagic (I love that software). I moved it down the disk by 32 MB, shrunk it by 20 GB, and converted /home/colin and my swap partition to logical ones. Windows still booted, even after formatting the partitions. I also used PM to switch the entries in the partition table, so that my partitions would be numbered in disk order--a change to BOOT.INI and Windows still worked.

Re: [gentoo-user] Reboot when GRUB starts

More likely is that grub gets confused trying to talk to the RAID BIOS, and either cannot decipher the ext2 filesystem to find the stage2, or loads what it thinks is the stage2 but turns out to be garbage that causes the reboot. One remaining possiblity here: try renaming /boot/grub/e2fs_stage1_5 to e2fs_stage1_5.sav. Then run: # grub --device-map=/boot/grub/device.map grub root (hd0,0) ... grub setup (hd0) ... grub quit ...

The stage1.5 is really a minimal stage2...it is supposed to contain just enough code to decipher the filesystem and locate the real stage2. So, here comes the bad news. If you do anything that moves, updates, or restores the stage2 file, you *must* run those setup instructions again. This is because the location of the stage2 is now block-mapped into the stage1. In fact, you might want to chattr +i /boot/grub/stage2, update package.mask to exclude new versions of grub, etc... Two commands inside a GRUB shell doesn't sound too bad.

Because hdparm doesn't specify the O_DIRECT flag on open, the kernel will buffer the data in system memory for the first read, and return the same for all subsequent reads. So the number returned equals 1/2 of your system memory bandwidth, since copying the buffer from one memory location to another involves both reading and writing. Oh OK. I thought the buffered result was kept in the drive's memory, not the system's. All right, since it's try-to-stump-Richard-day, let me throw out one more question. This one should be easier.

Re: [gentoo-user] problem booting from a USB flash drive
Zac Medico wrote: Probably. You can save space with a compressed filesystem like jjfs or squashfs. You probably want to mount it read only since flash has limited write cycles. You say the kernel messages indicate that the flash disk was recognized as sda so I'm not sure why it's not mounting for you. I looked through linux/Documentation/kernel-parameters.txt and saw a rootdelay parameter. With the modules I need a delay for the usb drivers to initialize. Maybe you need that too. Try rootdelay=5 or rootdelay=10 or something. Kind of off on a tangent, but there are other alternatives to a write-protected file system. Instead of using a USB flash disk, there are IDE-CompactFlash adapters that would achieve the same result but with 100% IDE compatibility, so the disk just shows up as /dev/hd[x] like a normal hard drive and doesn't require any rootdelaying or USB drivers. I don't know if CF cards are lockable, I know SD's are. CF is kind of costly, though, especially if you want faster media. SCSI wouldn't be worth the money here (disks can be write-protected at the hardware level via a jumper), but maybe a nice Ultra160 15 kRPM drive on your back-end server would make a good investment. -- Colin -- gentoo-user@gentoo.org mailing list
Re: [gentoo-user] /boot and booting...
On 6/5/05, Digby Tarvin [EMAIL PROTECTED] wrote: Following on from the recent discussions on grub and booting, is there a good reason for having a separate partition for /boot, other than perhaps to overcome BIOS addressing limitations for people with very large root partitions?? A separate /boot partition is more than likely for compatibility with older BIOSes. (You'll notice that other architectures, AFAIK, don't need it.) Some older BIOSes won't see past a certain limit (504 MB, 2.1 GB, 8.4 GB, 33.8 GB, 137 GB) and consequently, depending on your BIOS, if your boot partition extends past that limit or if your kernel image is stored past that limit (when using CHS instead of LBA), your system will be unbootable. Other OSes may observe the 1024-cylinder and/or the 2 GB boot boundaries. The BIOS 1024 cylinder limitation exists because the start and end cylinder values in the partition table, and some BIOSs, have a maximum value of 1024. Because some operating systems such as DOS 6.22 use the CHS (Cylinder, Head, and Sector) values to address sectors on the disk, they cannot access sectors beyond the 1024th cylinder. When you start your computer, the BIOS boots the operating system using the CHS values to locate the first sector of the bootable partition. If the partition starts past the 1024 cylinder, the BIOS may not be able to boot it because it cannot address a cylinder number higher than 1024. Defeat this limitation by using a BIOS with Int13h or LBA support, or by using Linux. :-) The 2 GB boot code boundary exists because, with some older OSes/BIOSes, the CHS value of the beginning boot code sector must be calculated in order to retrieve the sector's information and load and execute the next part of the boot process. Because of the way the boot code is written, the sector value, computed from the CHS value, must fit in a 16-bit register, thus the maximum value that can be kept is 64K. If the number is larger than 64K, the number is truncated, resulting in an incorrect value that skews the remaining calculations. The boot process fails to load and execute the needed sector, thus preventing the OS from booting. Most current hard disks have 63 sectors per track, creating a 64K boot code boundary at 2 GB. If a partition begins or extends beyond this boundary, the CHS value of the partition's boot code sector cannot be correctly calculated; therefore, the partition and its OS cannot boot. AFAIK, this only affects older OSes, like DOS and WinNT 4.0, and BIOSes that aren't set to LBA mode. Like not Linux. :-) (Paraphrased from the PowerQuest PartitionMagic help file. Please don't sue me.) Keeping /boot as a tiny partition at the front of the disk makes sure that your system can boot despite whatever curveball your old software can throw at it. If you're confident that these problems don't affect you, feel free to merge /boot and /. I usually don't do it, but I thought I'd try it out. Once the kernel kicks in, the kernel can do translation so that all of your disk is visible and usable. This is done by compiling in translation or passing hdx=stroke to genkernel kernels (LiveCD's included). Of course, drive overlay software is still an option if that's the way you like it, or if you dual-boot Windows. -- Colin -- gentoo-user@gentoo.org mailing list

Anyway, with Serial ATA here, IDE master/slave settings and all those SCSI jumpers (ID, termination, power on, SE/LVD, etc.) should be a thing of the past. If the BIOS autodetects drives, why would the OS have so much trouble? My guess is the Linux kernel chooses to bypass the slow BIOS and access the hardware directly, which is why options such as hdx=stroke work with older BIOSes. -- Colin -- gentoo-user@gentoo.org mailing list

[gentoo-user] GNOME takes forever to start
I shut down my computer normally. When I turned it on, though, after logging into GNOME about an hour ago, I'm still waiting for it to boot. I enter my password, wait forever, and then the Gentoo logo pops up. Wait forever again, and then the icons appear in the box, and then the box disappears. Now I'm still waiting forever. The last thing I remember doing is modifying /etc/conf.d/rc, emerging Thunderbird, and fetching some sources for another Gentoo box. I've tried failsafe GNOME, same thing. Failsafe terminal works, though. The mouse works and I can Ctrl-Alt-Backspace whenever I want and X/GNOME restarts. Anybody know what's going on?

How is that supposed to help -funit-at-a-time? From info gcc: The compiler performs optimization based on the knowledge it has of the program. Using the `-funit-at-a-time' flag will allow the compiler to consider information gained from later functions in the file when compiling a function. Compiling multiple files at once to a single output file (and using `-funit-at-a-time') will allow the compiler to use information gained from all of the files when compiling each of them. So -funit-at-a-time performs best when multiple C/C++ files are compiled by a single invocation of GCC. As Julien said, no makefiles in use today (AFAIK) support this. Oh, sorry.

My secrets? -O3: The highest performance optimization level before code starts to break. It goes up to -O9 if you're daring. (Use -Os to compile for size.) Implies a lot of stuff. -march=pentium2: Implies -mmmx and writes code specifically for the P2 processor. -mmmx: Build code with MMX instructions wherever possible. -fomit-frame-pointer: Don't keep the frame pointer in a register. You get an extra register at the cost of losing debugging ability. -pipe: Use pipes instead of temporary files. Not recommended on a RAM-limited system. -ftracer: Use the processor's branch predictor when compiling. I think it compiles twice with this flag, but it does compile more efficiently. -fno-rename-registers: Renaming registers is only done when running 32-bit code on a 64-bit processor. It's implied on x86 architecture anyway. -funroll-loops: If you can tell how many times a loop will loop (mainly for loops), then unroll it. Does it increase performance? If it does, it's unnoticeable. Don't tell anyone you use it though. It spreads the whole Gentoo ricer myth that's been going around the Internet.

[gentoo-user] ALSA drivers don't load - was Re: [gentoo-user] Soundcard not detected
I recompiled my kernel with ALSA enabled and my card (Dell OEM Aureal Vortex, driver snd-au8820) compiled as a module, which I added to /etc/modprobe.conf/kernel-2.6. I tried to emerge alsa-drivers, but it said it was unnecessary. I emerged alsa-utils successfully. When I went to run alsaconf, it said three times before the menu came up, modinfo: could not find module snd alsaconf seemed to work perfectly, and then it exited with a cheerful message.

[ ok ] I've attempted to modprobe snd-au8820 and its dependencies, snd-mpu401-uart and snd-ac97-codec before (re)starting alsasound, but that doesn't work, either. I followed the Gentoo ALSA guide to the letter. Once again, I must have misconfigured my kernel. (And yes, lspci now finds my soundcard. Didn't change anything, though.) I did all this from xterm within GNOME (logged in as myself but su'ed to root in the terminal), but that's probably not a problem since I've rebooted but still get the same errors when alsasound loads at runlevel 2 (boot). -- Colin -- gentoo-user@gentoo.org mailing list

[gentoo-user] Soundcard not detected
I'm trying to get my soundcard working. It isn't detected by lspci under my kernel, but the LiveCD's lspci finds it and detects it on the line :00:11.0 Multimedia audio controller: Aureal Semiconductor Vortex 1 (rev 02). The LiveCD coldplugs it as driver=unknown, but that shouldn't stop lspci from finding it. I'm guessing I forgot to compile something into the kernel (2.6.11-gentoo-r9)?

I had a problem where my machine wouldn't power off, but it would reboot, and it was just a kernel configuration problem. I doubt that, since when it reboots, there are more steps, ending with unmounting the filesystems and remounting them read-only.

[gentoo-user] Finally! But a few issues...
Finally! I have a working install of Linux 2.6.11-gentoo-r6 on a Pentium II machine that I plan to use as a portable media center. (Think of it as an iPod on steroids.) But I've got a few issues, as the subject line says. Linux newbie here, though I have done many unsuccessful Gentoo installations before, so my feet are wet. 1.) I've got Reiser3.6 on my / partition (/dev/hda3, /mnt/gentoo). I've also got Reiser3.6 on my /home partition (/dev/hda4, /mnt/gentoo/home), but I'd like to try Reiser4 out. I hear that in almost all cases, it's an extremely fast and safe file system. True, it's a working beta version, but my /home partition is disposable (any files I put there will be copied over from another computer, anyway, so I've always got a live backup) so I think I'll jump in. I found the Reiser4 emerge guide on the Gentoo forums, but that didn't work for me. Is there any way to emerge Reiser4 support into my kernel? 2.) This will be an embedded system, so how can I speed up the boot process (after the BIOS hands control to GRUB)? I've compiled a lot of stuff as modules so I can load and unload them whenever necessary, so that cuts down on boot time. Things I've noticed that take forever are Calculating module dependencies..., mounting Reiser3.6 partitions and DHCP detection (which I want). 3.) What's the Linux equivalent of DOS/Windows' autoexec.bat (something to run commands on startup, namely setterm -blank 0)? 4.) My USB key and/or a media card reader are sometimes plugged into this computer, but not always. It's a hassle manually mounting them every time I want to use it. Can I mount them in /etc/fstab even though it won't always be present at boot-time? Here's what I've got, commented out for now: /dev/sda1 /mnt/usbdrive vfat noatime 0 0 /dev/sdb1 /mnt/cards/cf-mdautonoatime 0 0 /dev/sdb2 /mnt/cards/sd-mmcauto noatime 0 0 /dev/sdb3 /mnt/cards/sm-xd auto noatime 0 0 /dev/sdb4 /mnt/cards/ms-mspro auto noatime 0 0 5.) And as far as my USB key is concerned, FAT32 is slow and unjournaled. It sucks. ReiserFS is the greatest thing since NTFS as far as I'm concerned, and I'd like to use that on my USB key, since it's speedy, journaled and space-efficient.
