Kernel - kompilácia
Neviem či som správne pochopil či je to ten kernel a čo obsahuje. Ak skompilujem zo zdrojáku kernel napríklad pre najaký MIPS alebo ARM procesor, tak sú sáčasťou aj ovládače napríklad sieť grafika atď ? Sú súčasťou aj nejaké aplikácie ako napr. Telnet server aby som sa vedel do toho pripojiť ?

Kompilaciou zdrojovych kodov pre urcite platformu ziskas binarne subory (kernel + ovladace) spustitelne pre tu konkretnu platformu, teda ak si to skompilujes pre ARM ziskas jadro spustitelne na ARM procesoroch.
Aplikacie nie su sucastou kernelu. Jedna sa o samostatne programy. V svete linuxu su casto tieto programy z projektu GNU, preto najdes na internete oznacenie systemu GNU/Linux (jadro Linux a programy=userspace, GNU). Ak by si jadro linuxu vymenil za freeBSD a ponechal programy GNU, ziskas system GNU/FreeBSD. atd.
Postupoval som tuším podľa tohoto:
update the scripts/image and add
$SCRIPTS/install util-linux
## BA DPLU
$SCRIPTS/install linux-tbs-drivers
## EA DPLU
in directory packages/linux-drivers/linux-tbs-drivers
change the install script like this
. config/options $1
VER=`ls $BUILD/linux*/modules/lib/modules`
## BA DPLU remove those three lines
#mkdir -p $INSTALL/lib/modules/$VER/tbs
#find $BUILD/${PKG_NAME}-${PKG_VERSION}/linux-tbs-drivers/ -name \*.ko -exec cp {} $INSTALL/lib/modules/$VER/tbs \;
#lib/modules/3.2.9/kernel/drivers/media
## BA DPLU
rm -Rf $INSTALL/lib/modules/$VER/kernel/drivers/media
mkdir -p $INSTALL/lib/modules/$VER/kernel/drivers/media
find $BUILD/${PKG_NAME}-${PKG_VERSION}/linux-tbs-drivers/ -name \*.ko -exec cp {} $INSTALL/lib/modules/$VER/kernel/drivers/media \;
## EA DPLU
mkdir -p $INSTALL/lib/firmware/
cp $BUILD/${PKG_NAME}-${PKG_VERSION}/*.fw $INSTALL/lib/firmware/
The meta file like this for the new name of zip file

At the end, when booting you will have a dmesg like this

A potom už samotná kompilácia http://wiki.openelec.tv/index.php?title=Compile_from_source.
Už by som do toho nešiel, pretože HTPC slúži aj ako NAS a HDD sú v RAID1. Openelec je dosť obmedzený, tak ten Ubuntu mini sa javí ako lepšia voľba.
