The following is a copy of my kernel config file. I am trying to optimize it as
much as possible.
do i need any of these psudo devices?
pseudo-device loop # Network loopback
pseudo-device ether # Ethernet support
pseudo-device sl 1 # Kernel SLIP
pseudo-device ppp 1 # Kernel PPP
pseudo-device tun # Packet tunnel.
pseudo-device pty # Pseudo-ttys (telnet etc)
pseudo-device md # Memory "disks"
pseudo-device gif # IPv6 and IPv4 tunneling
pseudo-device faith 1 # IPv6-to-IPv4 relaying (translation)
pseudo-device splash
do i need any of these devices?
device atadisk # ATA disk drives
device atapicd # ATAPI CDROM drives
options ATA_STATIC_ID # Static device numbering
Thanks,
Brian
