I recently merged the Gentoo 2.4.20-r2 sources and DevFS seems to be missing. It absolutely does not show up in the "make menuconfig" filesystems menu, or any other menu that I can see. So, I manually edit the .config file, adding: CONFIG_DEVFS_FS=y CONFIG_DEVFS_MOUNT=y With these changes, the kernel won't compile. make dep works, make bzImage exits with: [...snip] /usr/src/linux-2.4.20-gentoo-r2/include/linux/devfs_fs_kernel.h:241: warning: `devfs_get_name' defined but not used /usr/src/linux-2.4.20-gentoo-r2/include/linux/devfs_fs_kernel.h:246: warning: `devfs_register_chrdev' defined but not used /usr/src/linux-2.4.20-gentoo-r2/include/linux/devfs_fs_kernel.h:251: warning: `devfs_register_blkdev' defined but not used /usr/src/linux-2.4.20-gentoo-r2/include/linux/devfs_fs_kernel.h:255: warning: `devfs_unregister_chrdev' defined but not used /usr/src/linux-2.4.20-gentoo-r2/include/linux/devfs_fs_kernel.h:259: warning: `devfs_unregister_blkdev' defined but not used make[3]: *** [base.o] Error 1 make[3]: Leaving directory `/usr/src/linux-2.4.20-gentoo-r2/fs/devfs' make[2]: *** [first_rule] Error 2 make[2]: Leaving directory `/usr/src/linux-2.4.20-gentoo-r2/fs/devfs' make[1]: *** [_subdir_devfs] Error 2 make[1]: Leaving directory `/usr/src/linux-2.4.20-gentoo-r2/fs' make: *** [_dir_fs] Error 2[/code] I tried "make clean", "make mrproper", reconfigured the kernel from scratch using conservative options. I used the default build flags and the same with -O2. I figured that the patch may not have been applied when installing it (if devfs is patched onto the kernel during install), so unmerged it and completely deleted everything from /usr/src/* I then ran "emerge sync" and re-emerged gentoo-sources. Same thing. The Gentoo forums do not indicate thatanyone else has had this problem, but I am certainly not doing anything strange and have very little software--all stable (other than the kernel) installed. Reproducible: Always Steps to Reproduce: (if it can be reproduces by someone else) 1. emerge sync 2. emerge gentoo-sources 3. cd /usr/src/linux (make sure the symlink points to 2.4.20-r2) 4. make menuconfig ... no devfs options 5. make dep clean bzImage modules modules_install, reboot, Gentoo complains about lack of devfs. Alternatively, manually add the devfs options to your .config file and try.

System is an Athlon-MP (with only one processor), 1GB reg ECC RAM, newish Adaptec U160 card with SCSI drive for system, plenty of output from the power supply, excessive cooling, nothing fancy. Can compile all week without error.
i'm using 2.4.20-r2 on 2 machines with devfs, working great maybe mrproper breaks the kernel source ?
I cleared /usr/portage/distfiles and re-emerged gentoo-sources, and the devfs option showed up. <shrug> Go ahead and mark this as fixed, since it seems I am the only person on earth to experience it. Thanks for the hard work on Gentoo.
yeah, not having devfs would be huge news to me. it's definitely there. have a good one, Jay
