[arch-releng] [RFC] Switch from dm-snapshot to overlay
by Gerardo Exequiel Pozzi 29 Sep '15

Hello Guys, what do you think about switching to overlay filesystem by default? This is already implemented around Jan 2015 of this year. Why?: * It seems the most "natural" way. * Low RAM usage if user wants do to some changes inside live-enviroment. * No crazy crashes if zero-free-space is reached (some bbs/wiki talks posts ask about this) There is at least two issues at boot time: (1) /var/log/journal: Cannot set file attribute for '/var/log/journal', value=0x00800000, mask=0x00800000: Inappropriate ioctl for device (2) /etc/machine-id: Failed to unmount transient /etc/machine-id file in our private namespace: Invalid argument (1) Does not care. (2) Unsure about it. The file has an "id" after bootup, maybe the most safe thing to do, is to generate machine-id at build time (or at initramfs), instead of just placing an empty file and generate an "id" at runtime (on switched-root). # hostnamectl Static hostname: archiso Icon name: computer-vm Chassis: vm Machine ID: b0e5ffa9728f421dacf4564936dce6e1 Boot ID: 92e4f6a2202f49798cb0e4782e791daf Virtualization: kvm Operating System: Arch Linux Kernel: Linux 4.1.2-2-ARCH Architecture: x86-64

[arch-releng] [PATCH] cleaner boot from loopmounted iso file
by Adam Purkrt 13 Sep '15

13 Sep '15

Currently, when booting loopmounted iso file, it is necessary to specify not only img_dev and img_loop (which should be sufficient), but also archisolabel or archisodevice. With this patch, archisodevice is directly populated with the correct loop device, and it is not necessary to specify the label when booting from loopmounted iso, which makes for leaner and cleaner grub.cfg. --- archiso/initcpio/hooks/archiso_loop_mnt | 4 +++- docs/README.altbootmethods | 4 ++-- 2 files changed, 5 insertions(+), 3 deletions(-) diff --git a/archiso/initcpio/hooks/archiso_loop_mnt b/archiso/initcpio/hooks/archiso_loop_mnt index 46338e5..f95a47d 100644 --- a/archiso/initcpio/hooks/archiso_loop_mnt +++ b/archiso/initcpio/hooks/archiso_loop_mnt @@ -18,7 +18,9 @@ archiso_loop_mount_handler () { echo $(readlink -f ${img_dev}) >> /run/archiso/used_block_devices fi - if ! _dev_loop=$(losetup --find --show --read-only "/run/archiso/img_dev/${img_loop}"); then + if _dev_loop=$(losetup --find --show --read-only "/run/archiso/img_dev/${img_loop}"); then + archisodevice="${_dev_loop}" + else echo "ERROR: Setting loopback device for file '/run/archiso/img_dev/${img_loop}'" launch_interactive_shell fi diff --git a/docs/README.altbootmethods b/docs/README.altbootmethods index 3c07e03..9df20ef 100644 --- a/docs/README.altbootmethods +++ b/docs/README.altbootmethods @@ -31,14 +31,14 @@ Note: Described method is for using with GRUB2. menuentry "Arch Linux (x86_64)" { set isofile="/<TARGET-PATH>/archlinux-<YYYY>.<MM>.<DD>-dual.iso" loopback loop (hd<D>,<P>)$isofile - linux (loop)/arch/boot/x86_64/vmlinuz archisolabel=<FS-LABEL> img_label=<TARGET-FS-LABEL> img_loop=$isofile + linux (loop)/arch/boot/x86_64/vmlinuz img_label=<TARGET-FS-LABEL> img_loop=$isofile initrd (loop)/arch/boot/x86_64/archiso.img } menuentry "Arch Linux (i686)" { set isofile="/<TARGET-PATH>/archlinux-<YYYY>.<MM>.<DD>-dual.iso" loopback loop (hd<D>,<P>)$isofile - linux (loop)/arch/boot/i686/vmlinuz archisolabel=<FS-LABEL> img_label=<TARGET-FS-LABEL> img_loop=$isofile + linux (loop)/arch/boot/i686/vmlinuz img_label=<TARGET-FS-LABEL> img_loop=$isofile initrd (loop)/arch/boot/i686/archiso.img } -- 2.5.0
