Hence, now if you set - CONFIG_DEVFS_ONLY to 'Y' then you won't be able to access your discs - via ordinary device nodes. Naturally, the default is 'N' so that you - can still use your old device nodes. If you want to mount from devfs - entries, make sure you use: append = "root=/dev/sd_..." in your - lilo.conf. It seems LILO looks for the device number (major&minor) - and writes that into the kernel image :-( - -- support for character memory devices (/dev/null, /dev/zero, /dev/full - and so on).

Also only create - devfs entries for SCSI disc partitions which actually exist - Show new names in partition check - Thanks to Jakub Jelinek <jj@sunsite.ms.mff.cuni.cz> -=============================================================================== -Changes for patch v14 - -- bug fix in floppy driver: would not compile without - CONFIG_DEVFS_FS='Y' - Thanks to Jurgen Botz <jbotz@nova.botz.org> - -- bug fix in loop driver - Thanks to C.
