Do you pine for the nice days of minix-1.1, when men were men and wrote their own device drivers?
Are you without a nice project and just dying to cut your teeth on an OS you can try to modify for your needs?
Are you finding it frustrating when everything works on minix? No more all-nighters to get a nifty program working?
Then this post might be just for you :-)

1. Partial 'Grub' Tutorial
28�Mar�2000 (3 posts) Archive Link: "installation"
Topics: Bootloaders, FS: ext2
People: Neal H Walfield
In the course of discussion, Neal H Walfield gave some tips on using 'Grub':
In grub, the best way to verify that what you are doing is correct is to use the tab key a lot. Ie:
grub> root (hd0,<tab>
Possible partitions are:
Partition num: 0, Filesystem type unknown, partition type 0x82
Partition num: 1, Filesystem type is ext2fs, partition type 0x83
Partition num: 2, Filesystem type is ext2fs, partition type 0x83
Here I see that my first file system on hd0 is linux swap then the next two are ext2.
grub> root (hd0,1)
Filesystem type is ext2fs, partition type 0x83
grub> kernel /<tab>
Possible files are: lost+found usr home boot vmlinuz lib bin sbin etc var floppy dev cdrom initrd mnt proc root tmp vmlinuz-old
Grub 0.94 also has a nice find feature:
grub> find /boot/vmlinuz
Yup that is correct, (hd0,1) is my linux root.
Also, you may want to try out the new setup command, it automates the install process, very nice:
grub> help setup
setup: setup INSTALL_DEVICE [IMAGE_DEVICE]
Set up the installation of GRUB automatically. This command uses the more flexible command "install" in the backend and installs GRUB into the device INSTALL_DEVICE. If IMAGE_DEVICE is specified, then find the GRUB images in the device IMAGE_DEVICE, otherwise use the current "root device", which can be set by the command "root".
grub> setup (hd0)
Run "install ...
Note that Run actually means that it is running the commands that is is printing.
A final note, using the user land grub versus the boot grub can result in huge differences in order of the devices and installability. Therefore, as a general rule of thumb, you should use the boot grub. It is trivial to create a boot disk, just info grub for the full or:
# cd /boot/grub
# dd if=stage1 of=/dev/fd0 bs=512 count=1
# dd if=stage2 of=/dev/fd0 bs=512 seek=1
Assuming that the grub files are there (they may be in /usr/local/share/grub in which case, if you plan to install grub on the hdd, you need to copy them to /boot/grub).
By the way, the manual is very well done and an easy read.
This ended the (brief) thread.
2. 'shadowfs'; Translator Layering
31�Mar�2000�-�1�Apr�2000 (6 posts) Archive Link: "fs questions"
People: Neal H Walfield,�Zsombor Gergely
Zsombor Gergely asked how to use shadowfs under the Hurd, and Neal H Walfield explained that it had not yet been implemented. In reply to a private query, he gave links to Hurd Papers and the Hurd Reference Manual and added, "This is code waiting to be written. If you have ideas, and some ambition to get it done, feel free to hack some code out. If you do, talk to Thomas."
Zsomber had also asked about translator layering, saying, "if I already settransed a blockdevice to /mnt and I want to set - say - a gzip translator on top of it, what will be the "source" and the "destination" for such a settrans?" Neal recommended reading 'info hurd', but also explained, "The block device is the source for the store and the store is the source for gzip. This is called dereferencing, by default, settrans replaces existing translators, however, using the -L (--dereference) flag allows translator stacking."
3. New GNU Site In India; URLs For Newcomers
31�Mar�2000�-�1�Apr�2000 (3 posts) Archive Link: "gnu-india.org under construction"
People: Neal H Walfield,�Jim FranklinSomeone gave a pointer to GNU India, saying that it was hosted by TurboLinux, and would focus almost exclusively on the Hurd. Neal H Walfield and Jim Franklin welcomed the poster aboard, and Jim added a bunch of links to get started:
