hi guys. I want to build a cutom liveos by lorax.
my first liveos , dracut miss 'livenet' module, so it can **NOT** boot under PXE
boot failed message:
dracut: FATAL: Don't Know how to handle 'root=live:http://...squashfs.img'
first create command:
livemedia-creator --no-virt --make-iso --ks=centos7.liveos.ks.cfg
After I add 'dracut-network' package in centos7.liveos.ks.cfg '%package' section,
the second create liveos with 'livenet' module can boot from PXE successfully:
livemedia-creator --dracut-arg="--no-hostonly" --no-virt --make-iso --ks=centos7.liveos.ks.cfg
But squashfs.img size increased was larger than the size initramfs.img increased.
I hope to slim 'squashfs.img' size, so it could boot from PXE speedily.
I mount the squashfs.img compare the different size of these two liveos,
the different size was **only** at initramfs.img
install size was increase on 11M, but squashfs.img increase 50M :
# df -h
...
/dev/loop1 296M 296M 0 100% /mnt/1 <-- squashfs.img size
/dev/loop2 21G 817M 20G 4% /media/1 <-- install size
...
/dev/loop3 346M 346M 0 100% /mnt/2 <-- squashfs.img size
/dev/loop4 21G 828M 20G 4% /media/2 <-- install size
'du -sh' show it under '/boot' direcory.
