What are the implications of doing most BLFS stuff on the host system in
chroot, as opposed to doing it on the running target system? In my
ignorance, I would have thought that using chroot on the target system
was the way to go.
For a standard system, most packages can be built in chroot. Some
packages may require virtual file systems to be mounted. I'll include
my script below.
For systemd, I suspect that building in chroot may not be so easy,
especially if the host is not running systemd.
Personally, my preference is to build ssl/ssh and build everything via
and ssh login to the new system. That works for virtual systems like
qemu or vmware too. One issue though is that some graphical packages
require to be on the hardware to run checks.
