Can some one provide me with pointers to the funtion of the /initrd
directory in Debian ?
/initrd as with all other distro is used by the initrd.img file during
its bootup ( loading of modules ) during the kernel boot process
- in lilo/grub, if initrd=blah.img is not specified, than /initrd is not needed
Can some one provide me with an explanation of the exact funtion of the
/linuxrc executable in Debian ?
/linuxrc is required inside any blah.img ramdisk file to tell the boot kernel
what to do ...
usually: modprobe e1000
or more complicated things to load besides one module
Can some one explain why the /usr/share/initrd-tools/linuxrc file does not
have the executable flag set on my system ?
/usr/share/initrd-tools is like the man pages and reference only
and is never used
as you note /linuxrc should be root owned and executable
Are /initrd and /linuxrc mutually exclusive ? (The presence of one causes
the other not to be present)
no ... they are concurrcently required... if one initrd.img is used,
than both /initrd and /linuxrc is required
note, that /linuxrc is inside initrd.img
and that /linuxrc is NOT part of the normal system
more boot craziness
