contents of /dev change at every boot?
after realizing that many files in /dev are not used at all, i removed all of them there and then followed instructions from linux from scratch to create only those device files i need. i wasn't aware of dsp, so i didn't create it. then i found out that i needed it to have sound; so i created it like this "mknod -m 660 /dev/dsp c 14 0." then i got sound.
however, after reboot, no sound -> i looked in /dev. dsp was gone -> recreated it -> reboot -> dsp was gone -> ... and not only dsp that kept disappearing, but also the intructions file from lfs that i copied into /dev.
now i have to add "mknod -m 660 /dev/dsp c 14 0" to /etc/rc.d/rc.local.
any ideas on what's going on? thanks.
