I believe it is possible to use btrfs for /boot, but it must be the main volume (not a subvolume). The automatic btrfs layout is similar to how we do the lvm automatic partitioning. You'll get one btrfs partition on each disk with enough space (just sda4 in your case), and these are combined to form a single btrfs volume/filesystem. Subvolumes are created for / and /home. The main volume is not mounted directly. /boot (ext4) is a regular partition, as is swap. If grub2 learns how to identify subvolumes we will probably move /boot into the btrfs volume as well. > > > Reposting my kickstart: > ###################################### > install > text > lang en_US.UTF-8 > keyboard us > rootpw testpwd > firewall --service=ssh > authconfig --enableshadow --passalgo=sha512 > selinux --enforcing > timezone --utc Asia/Kolkata > bootloader --location=mbr --driveorder=sda --append="rhgb console=tty0 > console=ttyS0,115200 rd_NO_PLYMOUTH" > zerombr > clearpart --all --initlabel > autopart --type=btrfs > > %packages > @core > @editors > %end > ###################################### > > Also, to fix the serial console line-break issue, I disabled the plymouth service : > > $ ln -s /dev/null /etc/systemd/system/plymouth-start.service > > > > > >> > >> > >> ==> virt-install cmdline <== > >> ######################################################################################### > >> $ virt-install --connect=qemu:///system \ > >> --network=bridge:br0 \ > >> --initrd-inject=./ks-with-btrfs.ks \ > >> --extra-args="ks=file:/ks-with-btrfs.ks console=tty0 console=ttyS0,115200 > >> root=live:http://dl.fedoraproject.org/pub/alt/stage/17-Beta.RC4/Fedora/x86_64/os/LiveOS/squashfs.img"; > >> \ > >> --name=f17t1 \ > >> --disk /export/vmimgs/f17t1.img,size=20 \ > >> --ram 2048 \ > >> --vcpus=2 \ > >> --check-cpu \ > >> --accelerate \ > >> --hvm \ > >> --location=http://dl.fedoraproject.org/pub/fedora/linux/development/17/x86_64/os/ \ > >> --nographics > >> ######################################################################################### > >> > >> => Contents of my btrfs ks file <= > >> ######################################################################################### > >> $ cat ks-with-btrfs.ks > >> ## A minimal fedora kickstart file > >> > >> install > >> text > >> lang en_US.UTF-8 > >> keyboard us > >> rootpw testpwd > >> firewall --service=ssh > >> authconfig --enableshadow --passalgo=sha512 > >> selinux --enforcing > >> timezone --utc Asia/Kolkata > >> bootloader --location=mbr --driveorder=sda --append="rhgb console=tty0 > >> console=ttyS0,115200 rd_NO_PLYMOUTH" > >> zerombr > >> clearpart --initlabel > >> part /boot --fstype ext4 --size=600 > >> part / --fstype btrfs --size=14000 > >> > >> > >> %packages > >> @core > >> @editors > >> %end > >> ######################################################################################### > >> > >> > >>> > >>> Thanks, > >>> /kashyap > >>>> > >>>> it was a bit better with live - I was able to play with > >>>> filesystems without the installer crashing, however, I could not > >>>> install on btrfs as the target filesystem has to match the live > >>>> image > >>>> > >>>> there may have been some fixes since ... > >>>> > >>>> K. > >>>> > >>>> > >>>> > >>>> > >>> > >> > > > > > > > -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
