8.0 Chapter 8 Setup
8.0.S Entering chroot environment
Run as root
Check mounted or not
findmnt | grep $LFS
Output if LFS IS MOUNTED:
├─/mnt/lfs /dev/sdb2 ext4 rw,relatime
│ ├─/mnt/lfs/dev udev devtmpfs rw,nosuid,relatime,size=1981744k,nr_inodes=495436,mode=755,inode64
│ │ ├─/mnt/lfs/dev/pts devpts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000
│ │ └─/mnt/lfs/dev/shm tmpfs tmpfs rw,nosuid,nodev,relatime,inode64
│ ├─/mnt/lfs/proc proc proc rw,relatime
│ ├─/mnt/lfs/sys sysfs sysfs rw,relatime
│ └─/mnt/lfs/run tmpfs tmpfs rw,relatime,inode64
Output if LFS IS NOT MOUNTED:
├─/mnt/lfs /dev/sdb2 ext4 rw,relatime
Mount virtual filesystem if not mounted
mkdir -pv $LFS/{dev,proc,sys,run}
mount -v --bind /dev $LFS/dev
mount -v --bind /dev/pts $LFS/dev/pts
mount -vt proc proc $LFS/proc
mount -vt sysfs sysfs $LFS/sys
mount -vt tmpfs tmpfs $LFS/run
if [ -h $LFS/dev/shm ]; then
mkdir -pv $LFS/$(readlink $LFS/dev/shm)
else
mount -t tmpfs -o nosuid,nodev tmpfs $LFS/dev/shm
fi
Enter chroot environment
chroot "$LFS" /usr/bin/env -i \
HOME=/root \
TERM="$TERM" \
PS1='(lfs chroot) \u:\w\$ ' \
PATH=/usr/bin:/usr/sbin \
/bin/bash --login
8.0.E Exiting chroot environment
When you want to exit just do this
exit
8.0.X Pre-flight Checks
Make sure you are in
(lfs chroot) root:/# |
Create version-check.sh (See Section 7.12T on creating version-check.sh)
Run version-check.sh to see version requirements(Make sure all is OK)
bash version-check.sh
Check your “NPROC”, and “MAKEFLAGS” environment variables
echo "NPROC=$(nproc) MAKEFLAGS=$MAKEFLAGS"
Set MAKEFLAGS variable
export MAKEFLAGS='-j4'
8.0.B Backup
See Section 7.13.2 on backing up the LFS system.
8.3 Man-pages install
Approximate time required: 0.15 SBU
cd /sources/
time {
tar xf man-pages-*.tar.*
cd man-pages-*/
# Installation here
rm -v man3/crypt*
make prefix=/usr install
}
cd /sources/
rm -rf man-pages-*/
8.4 Iana-Etc install
Approximate time required: basically no time
cd /sources/
time {
tar xf iana-etc-*.tar.*
cd iana-etc-*/
# Installation here
cp services protocols /etc
}
cd /sources/
rm -rf iana-etc-*/
8.5 Glibc
Approximate time required: 52.75 SBU
8.5.1 Compile and check
cd /sources/
time {
tar xf glibc-*.tar.*
cd glibc-*/
# Installation here
patch -Np1 -i ../glibc-2.38-fhs-1.patch
patch -Np1 -i ../glibc-2.38-memalign_fix-1.patch
mkdir -v build
cd build
echo "rootsbindir=/usr/sbin" > configparms
../configure --prefix=/usr \
--disable-werror \
--enable-kernel=4.14 \
--enable-stack-protector=strong \
--with-headers=/usr/include \
libc_cv_slibdir=/usr/lib
make
make check
}
Check last output for test results.
A few failures out of over 5000 tests can generally be ignored.
Common failures:
-> io/tst-lchmod
-> stdlib/tst-arc4random-thread
8.5.2 Install and configure
