Minimal Root-FS frankensteinian style (part 2)

... continued from part 1.

creating basic filesystem structure (fedora-style)

DIRS="/etc/init.d /etc/rc.d /dev /root /media /mnt /proc /sys /run /tmp /usr/lib /usr/share /var/lib /var/db /var/cache /var/log /var/run /var/tmp /var/spool"

for x in $DIRS; do mkdir -p $FSROOT$x ; done
cd $FSROOT && ln -s usr/lib lib
cd $FSROOT && ln -s usr/lib usr/lib64
cd $FSROOT && ln -s usr/lib64 lib64


setting basic hostname for booting

echo busybox > $FSROOT/etc/hostname


basic mount points. for a chroot you may want to hash out the "/dev/root" entry.

cat <<__EOT__ > $FSROOT/etc/fstab
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc   proc        defaults                0       0
none            /tmp    tmpfs       defaults                0       0
mdev            /dev    devtmpfs    defaults                0       0
sysfs           /sys    sysfs       defaults                0       0
tmpfs           /dev/shm tmpfs      defaults                0       0
devpts          /dev/pts devpts     defaults                0       0
#/dev/root       /       ext2        rw,defaults,errors=remount-ro       0       1
__EOT__


basic minimal user/group files.

curl https://salsa.debian.org/debian/base-passwd/raw/master/passwd.master > $FSROOT/etc/passwd

curl https://salsa.debian.org/debian/base-passwd/raw/master/group.master > $FSROOT/etc/group


basic minimal name/service/protocol resolution.

echo "127.0.0.1   localhost localhost.localdomain" > $FSROOT/etc/hosts
echo "::1         localhost localhost.localdomain" >> $FSROOT/etc/hosts

echo "nameserver 8.8.8.8" > $FSROOT/etc/resolv.conf
echo "nameserver 1.1.1.1" >> $FSROOT/etc/resolv.conf

curl https://salsa.debian.org/md/netbase/raw/master/etc-services > $FSROOT/etc/services

curl https://salsa.debian.org/md/netbase/raw/master/etc-protocols > $FSROOT/etc/protocols


this should make the basic chroot complete but is still unable to run glibc/java apps.
